Messages garbage collector

/v1/services/message/gc

The /services/message/gc endpoint provides a way for businesses to delete messages from the database associated with their WhatsApp Business API client.

Before You Start

• It is recommended you run this API request multiple times on larger databases (i.e., databases with a messages table containing more than 10 million rows) to ensure the callbacks returns a complete status and no errors.

Request

PUT /v1/services/message/gc

Response

HTTP responses

You should receive a response indicating the API request is being processed.

Single instance

{
    "services": {
        "message": {
            "gc": {
                "status": "processing"
            }
        }
    },
    "meta": {
        "api_status": "stable",
        "version": "3.0.0"
    }
}

Multiconnect

{
    "services": {
        "message": {
            "gc": {
                "wacore2:9dfe77618dba": {
                    "status": "processing"
                },
                "wacore3:a9dcc716fd6e": {
                    "status": "processing"
                }

    },
    "meta": {
        "version": "v2.29.1",
        "api_status": "stable"
    }
}

Webhook notifications

Since the API request works asynchronously, once the garbage collection on the messages table is complete, the WhatsApp Business API client will post a notification to the callback server in the following format.

Note:

• For Multiconnect deployments, there will one notification posted per Coreapp.
• The node field in the notification is optional and omitted for single instances.
