/v1/settings/business/whatsapp_business_encryption
The WhatsApp Flows user experience requires an encrypted GraphQL-powered data exchange channel between the WhatsApp mobile consumer client and the third party business endpoint. Businesses generate a 2048-bit RSA key pair to establish the data channel and share their Business Public Key with WhatsApp consumer clients.
Use the /v1/settings/business/whatsapp_business_encryption
endpoint to publish and sign your Business Public Key.
The phone number must be successfully registered, and the business must have generated a 2048-bit RSA Key.
Generate a public and private RSA key pair by typing in the following command:
openssl genrsa -des3 -out private.pem 2048
The generates 2048-bit RSA key pair encrypted with a password you provided and is written to a file.
Next, you need to export the RSA public key to a file:
openssl rsa -in private.pem -outform PEM -pubout -out public.pem
You can then use it, for example, on your web server to encrypt content so that it can only be read with the private key.
You could also re-use an existing private/public key pair by extracting a public key from existing certificate:
openssl x509 -pubkey -noout -in private.pem > public.pem
Make a POST
API call to sign your business public key. If you have multiple phone numbers linked to a WABA, this API must be called to sign the business public key for each phone number.
In Postman, when inputting the business public key as a parameter in the Body, select x-www-form-urlencoded.
POST /v1/settings/business/whatsapp_business_encryption { "public_key": "2048_bit_RSA_key" }
A successful request returns Http status code 200
and the payload:
{ "meta": { "api_status": "stable", "version": "<latest-api-version>" } }
If you encounter any errors, see Error and Status Messages.

A successful response will have the 2048-bit RSA key and a signature status.
