January 10, 2023 (v2.45.1)

The 2.45.1 version of our Business API client is available today and includes:

• Security Improvements
  • We updated key dependencies of On-Premise client and monitoring stack fixing critical vulnerabilities and making prometheus monitoring transport using secure protocol. 2 environment variables are introduced which will be be used to enable the securing of the SSL connection, and to ensure verification of the webapp certificate. These new environment variables are:
    • WA_SKIP_SSL_VERIFICATION is going to be used to enable, and disable ssl verification. Valid values are TRUE or FALSE.
    • WA_SSL_CA_PATH gives the path to the certificate which can be used to verify the webapp certificate used by the businesses. This is useful if businesses are using a self-signed certificate or certificate that was signed using their own Certificate Authority. The path here should be accessible from the container so it needs to added as a volume. If WA_SKIP_SSL_VERIFICATION is set to TRUE, this value is ignored.
• Service reliability
  • Errors such as “invalid namespace” would happen at times when trying to send template messages while the HSM packs weren’t loaded yet. This has been fixed, now businesses will encounter a new error “Coreapp is not ready” whenever they try to use the messaging endpoint before the client is not fully ready.
• Database Performance Improvement
  • We have improved the database query execution time by reducing round trips between client and database server. There are also some new DB indexes to improve performance of some heavy queries on message send path.
• Stability and bug fixes
  • Message deleted webhook is working again. When businesses send a message to the consumer and deletes it, the business will receive a webhook.
  • out_message_persisted prometheus metric has been fixed and is working again
  • Video thumbnail is fixed. When sending videos, the thumbnail was sometimes missing and consumers couldn’t see the first frame before playing the video.
• New field in message sent status webhook notification
  • We introduced a new field media_id in the message sent status webhook notification for all media messages.

2022

November 24, 2022 (v2.43.2)

The 2.43.2 version of our Business API client is available today and includes:

• Fix for deleted message webhook notifications
  
  1. There was a bug in the v2.43.1 release which caused deleted message status webhook notifications to not be delivered. No other internal clean-up procedures were impacted except for sending this webhook notification in v2.43.1

October 11, 2022 (v2.43.1)

The 2.43.1 version of our Business API client is available today and includes:

• Changes to contacts node
  • Responses from contacts requests will no longer provide status information about a phone number. contacts can still be used to preload contact information before sending a message to the number. This can improve send message performance when sending messages in large volumes
• New API for blocking contacts
  • We are introducing a new API which will allow businesses to block and report customers who are sending obscene content, using inappropriate language, or harassing businesses’ employees
• Media reliability improvements
  • Improved reliability for media message sends (including template media messages) in cases where the same media is sent at a high throughput, such as during campaigns
• Extended API timeout
  • The timeout for API requests has been increased to 120 seconds. This is a short-term mitigation to reduce the number of timeouts for operations that are still being processed by the API client
• Incoming contact message fix
  • Incoming contact messages will now correctly show a contact’s company and department
• Stability and bug fixes
  • Fixing crashing issues when sending message right after registration
  • Fixing an issue with the web app so special charactors in password are handled correctly
  • Adding a new table index on message_receipt_log

September 19, 2022 (v2.41.3)

The 2.41.3 version of our Business API client includes:

• Adding a new table index on message_receipt_log that could benefit partners with high throughput needs (sending more than 200 messages / second)

June 27, 2022 (v2.41.2)

The 2.41.2 version of our Business API client includes:

• Improvements to the latency of the bulk /contacts endpoint requests and resolution of deadlock issues
• Improvements to the performance and reliability of the garbage collection process
• Businesses now have the ability to enable/disable delivered and read webhook notifications which gives them greater control over webhook notifications for messages. This can be achieved through the settings/applications endpoint
• namespace field is optional for the template object
• More robust handling of media download errors so businesses should experience less issues downloading media sent by customers
• Additional reliability and bug fixes within the send message and registration workflows
• The caption property is limited to 1024 characters This change only applies to captions on media messages being sent on v2.41.2. There is no impact on previously sent messages with other versions. No character limitations have been introduced on other message types

May 10, 2022 (v2.39.4)

This client version contains all features and fixes shipped with v2.39.1. Additionally, this release:

• Fixes a bug that prevented video messages from being sent under certain circumstances. This fix was also included in v2.39.2.
• Fixes a bug that prevented businesses from sending messages to a customer, if the consumer was the first to initiate an interaction between the two parties on WhatsApp, and that initiation happened more than 7 days ago. This fix was also included in v2.39.3.
• Fixes a bug that prevented businesses from receiving disappearing messages from customers. After v2.39.4 is installed, businesses will get notified they received a disappearing message by a webhooks notification with type set to "ephemeral". Businesses will not be able to see the message's content.

When we launched v2.39.3, the disappearing messages issue was handled by WhatsApp automatically disabling these messages in the chat thread with the client. For v2.39.4, we will not do that. With this version, businesses that receive disappearing messages must ask the customer to disable disappearing messages and resend their latest message.

Mar 25, 2022 (v2.39.3)

The v2.39.3 version of our Business API client is available for developers today. The new client includes two fixes and additional logs to support debugging. The two fixes are:

• Fixed a bug that prevented businesses from sending messages to a customer, if the consumer was the first to initiate an interaction between the two parties on WhatsApp, and that initiation happened more than 7 days ago.
• Fixed a bug that prevented businesses from receiving disappearing messages from customers. After v2.39.3 is installed, businesses will get notified they received a disappearing message by a webhooks notification. On their end, customers will see a warning saying that the disappearing messages mode has been turned off.

Mar 4, 2022 (v2.39.2)

Fixed bug that prevented video messages from being sent under certain circumstances.

Known Issues

• A bug exists that prevents businesses from sending messages to a customer, if the consumer was the first to initiate an interaction between the two parties on WhatsApp, and that initiation happened more than 7 days ago.
• A bug exists that prevents businesses from receiving disappearing messages from customers.

Feb 1, 2022 (v2.39.1)

The 2.39.1 version of our Business API client is available for developers starting today. The new client includes:

• New field for the Set Shards API.
• New hostname added to network requirements.
• New error code 1031.
• Deprecations of the hsm type and the webhook_payload_conversation_pricingmodel_disabled application setting.

Set Shards API

Starting with the new API client version, you may provide your phone’s certificate when you are setting up multiconnect. That means that, when calling the /v1/account/shards endpoint, you can add the Base64-encoded certificate in the cert field. See Scale Your API Client With Multiconnect for information.

New Hostname

We have added graph.whatsapp.com to the list of WhatsApp server hostnames that the Business API client requires connectivity to. See Set Up and Debug Your Network, Hostnames for information.

Error Code Updates

With v2.39, we have added error code 1031. You will get this error if your account has been locked and can’t send any messages due to an integrity policy violation. See Error and Status Messages and Policy Enforcement for information.

Deprecations

• Messages API: The hsm type has been deprecated with v2.39. You should use the template type instead.
• Application Setting: The application setting webhook_payload_conversation_pricingmodel_disabled has been deprecated.

Known Issues

Some video messages fail to send under certain circumstances.

March 26, 2022 (v2.37.2)

This version contains the same features as v2.37.1, but there's a different expiration date. v2.37.2 expires on Sep 22, 2022.

Known Issues

Some Kubernetes developers may see CrashLoopBackOff for their webapp container and their container may fail to start. To fix that, add following line in the Kubernetes deployment YML file under webapp configuration:

command: ["/opt/whatsapp/bin/wait_on_mysql.sh", "/opt/whatsapp/bin/launch_within_docker.sh"]

2021

Sep 30, 2021 (v2.37.1)

This new version of the API introduces:

• Commerce Messages. (Businesses in India have to follow a set of different rules and have access to a new endpoint: /settings/business/compliance_info).
• New webhook fields to support Conversation-Based Pricing.
• New webhook field inside the statuses object.
• Deprecation announcements for Messages API, Application Settings API, and pricing.

Commerce Messages

This version of the API introduces two new types of interactive messages: Single Product Messages and Multi-Product Messages. Users that receive these messages can view products, add them to a shopping cart, and send the cart back to businesses.

Both Multi and Single Product Messages lend themselves best to user experiences that are simple and personalised, where it’s a better experience to guide the customer to a subset of items most relevant to them, rather than browsing a full catalog. They work best when combined with navigation tools like natural language processing, text search or List Messages and Reply Buttons to get to what the customer is looking for fast. See Commerce Guides for more information.

Commerce Messages in India

API businesses in India (+91 phone number) can start integration from today, but will only be able to send Multi-Product or Single Product messages after 15 November 2021. The Laws enacted by the Department of Consumer Affairs in India require you to provide additional information to customers in your Business Profile and Product Detail Pages.

With the WhatsApp Business API v2.37, businesses in India also gain access to the /settings/business/compliance_info endpoint. See more information here.

Conversation-Based Pricing

We have previously announced that the WhatsApp Business API will switch from a notification-based pricing model to a conversation-based pricing (CBP) model on February 1, 2022. To support your efforts in getting ready for the new pricing system, this version of the API introduces new webhook fields. The webhooks field listed below will only start showing up on your webhooks on February 1, 2022.

See examples of the new webhooks here.

New Webhooks Field For the Statuses Object

The webhooks statuses object now includes a type field. Currently, the only supported type is "message".

Deprecations

• Messages API: The hsm type will be deprecated when we launch the WhatsApp Business API v2.39. You should use the template type instead.
• Application Settings: The setting webhook_payload_conversation_pricingmodel_disabled will be disabled on February 1, 2022.
• Pricing:

  • Notification-Based Pricing will be deprecated on February 1, 2022. With it, the "NBP" webhook field under pricing_model will also be deprecated.
  • The webhooks billable flag that was added for the Mexico conversation-based pricing test is scheduled to be deprecated as early as March 2022. We recommend that you stop using this field before upgrading to the next version.

Jun 28, 2021 (v2.35.4)

Fixes:

• Retry mechanism for Reply Buttons messages on multi-device.
• Check on incoming message maximum size to prevent MySQL errors.
• Memory issues.

May 26, 2021 (v2.35.2)

Interactive Messages

This version of the API allows you to send interactive messages, which includes list messages and reply button messages. These new features give users a simpler way to find and select what they want from your business during an interaction on WhatsApp. During testing, chatbots using interactive messaging features achieved significantly higher response rates and conversions compared to those that are text-based.

The following messages are considered interactive:

• List Messages: Messages including a menu of up to 10 options. This type of message offers a simpler and more consistent way for users to make a selection when interacting with a business.
• Reply Buttons: Messages including up to 3 options —each option is a button. This type of message offers a quicker way for users to make a selection from a menu when interacting with a business. Reply buttons have the same user experience as interactive templates with buttons.

At the API level, interactive messages are set by specifying a message’s type to interactive and adding the interactive object. Generally, these messages include 4 main parts: header, body, footer, and action.

For more information, see our Sending Interactive Messages guide.

Deprecations

TTL

The ttl parameter has been deprecated. Moving forward, any POST requests to /messages that include this field will return an error message. Previously, this field was only accepted for messages of type hsm and template

Passthrough Setting

Starting with v2.35, you can no longer re-enable the pass_through setting for WhatsApp Business API Clients.

Mar 10, 2021 (v2.33.4)

• [Fixed] Webhook notifications for delete message events are sent to the business successfully.

Feb 23, 2021 (v2.33.3)

General Updates

• All the docker images are now running Ubuntu 20.04. External libraries are all using latest version: php 7.4, openSSL 1.1.1, and Lighttpd 1.4.55.
• [Deprecation] The WhatsApp Web Business Tool (deprecated since v2.29.1) will no longer be available through the Webapp URL. Postman is now the recommended way of accessing the REST API.
• [Fixed] Security vulnerabilities within the Grafana monitoring instance.

In-Thread Context for ads that Click to WhatsApp

Starting April 21, 2021, as part of API v2.33, businesses will have access to the In-Thread Context feature for ads that click to Whatsapp. With In-Thread Context, a consumer can easily reference the ad they tapped on, and a business can understand which messages come from which ads, making the first interaction more convenient, personal and efficient.

Initial tests have shown In-Thread Context to increase the number of conversations and reduce the cost per conversation.

In order to enable In-Thread Context, the business or Business Service provider that is hosting API v2.33 needs to update their inbound webhooks integration to read a new 'referral' property added to inbound messages by April 21.

After April 21, consumers will be able to send the In-Thread Context via message attachment, containing the header, body image and video related to the ad.

If the advertiser does not complete the above updates by April 21, they will not be able to receive the attachment, and will miss important context on what the customer is messaging about. The consumer will see the ad context, and will expect the business to as well.

Conversation-based pricing

Since February 1, 2021, we have been testing a new pricing model for the WhatsApp Business API that impacts businesses messaging users with a Mexico phone number.

To support this effort, some message webhooks notifications now include the new conversation and pricing objects —only messages with status sent, delivered, and read are impacted. For more information, see Message Status Notifications.

Oct 20, 2020 (v2.31.4)

• A stricter version expiry has been enforced beginning with this version and for all previous versions.
• Identity change notification
  • Businesses using the WhatsApp Business API can choose to be notified when there has been a potential update to the identity of a user with whom they are communicating. This gives businesses a signal that the person behind the account may have changed so a business can verify that they are sending information to the right number.
  • If a business opts in to this feature, they will be informed when they receive messages from WhatsApp accounts where the person controlling the account may have changed and will be blocked from sending messages to those accounts until the business acknowledges receipt of the signal and they feel it is safe to continue communications. This will protect the business and their customers from leaking sensitive information.

Dependencies/Prerequisites:

This template requires WhatsApp Business API client version v2.18.14 or later. This template will not work with prior releases.

Changelog:

• Support for a configurable log driver for containers. The default log driver is json-file, which stores the logs as a JSON file on the hosts (EC2) where containers are run. This template also provides an option to configure awslogs, where all container logs are streamed to CloudWatch. This makes all logs available in one place. When the awslogs option is selected, the container logs will not be available on the EC2 hosts. However, the log files inside a container will continue to exist.
• Added all SSL parameters — SSL certificate, SSL key and SSL CA. SSL CA support was added in the 2.2.0 release, but the description is rephrased to avoid ambiguity.

Release 2.2.0

Dependencies/Prerequisites:

This template requires WhatsApp Enterprise client version v2.18.14 or later. This template will not work with prior releases.

Changelog:

• Support for "static" HA
  • Staging environment: Minimum container (EC2) instances: 2, Max: 3, Desired number of master, coreapp and web containers: 2
  • Production environment: Minimum container (EC2) instances: 3, Max: 4, Desired number of master, coreapp and web containers: 3
  • This option is disabled by default
• Encryption support (RDS/DB & EFS)
  • Data at rest can be encrypted with new release. Default option is to use default AWS service key to encrypt it. Other supported options are:
    • Don't encrypt
    • Create a new key and use that
    • Encrypt using user provided key
• DB connection encryption support
  • Data in transit to database can be encrypted with new release. Caveat: This is applicable for coreapp only at this point. Web app encryption is not supported yet. In addition, with new DB engine, even if this is not set, coreapp seems to perform encryption, without server cert verification.
• Support for Beta release channel
  • WhatsApp has setup a beta channel to test new set of templates that is not in production. Customers require separate access to Beta channel/templates
• Configurable container registry support
  • New template has configurable container registry, which can be used to get access to experimental enterprise client releases in future. In most cases, default value is good
• Support for new region (us-west-1: N California)
  • AWS EFS service is now supported in N California region. Any customer interested in using this region should be given access
• DB password is stored in secure parameter store to limit exposure
• DB (MySQL) engine version updated to 5.17.21
• Template versioning for nested templates
  • We link all the referenced nested templates with correct versions. This will avoid mismatch among template versions (E.g., main template → database template)
• Support for configuration on DB
  • Configuration on DB is no more an experimental feature and set to enabled by default. Customer still has an option to turn it off
• Bug fixes:
  • Found a bug in EFS mount order, where EFS volume is mounted after container is started. This happened once out of 100+ tries, but a nastier one. The issue is fixed by enforcing the order.
  • Due to timing issue, port mapper required few retries to find the correct external port mapping for HA to work. This was a non-issue prior to HA; however, the issue is fixed by adding adequate retries

Note: Please use experimental/beta features with caution. It's highly recommended to work with WhatsApp team closely when using these features so that we can support you quickly, if there are any issues.

Known Issues:

WhatsApp Enterprise client doesn't work when HA is disabled. This will be addressed in next WhatsApp Enterprise Client release.
