Send Flow API giving Unsupported post request

Error messsage

Flow created

I'm trying to send a flow but I'm always getting that the object id doesn't esxist (the phone number).

curl --location 'https://graph.facebook.com/v18.0/5731.../messages' \ --header 'Authorization: Bearer EAA...' \ --header 'Content-Type: application/json' \ --data '{ "recipient_type": "individual", "messaging_product": "whatsapp", "to": "5841..", "type": "interactive", "interactive": { "type": "flow", "header": { "type": "text", "text": "Flow message header" }, "body": { "text": "Flow message body" }, "footer": { "text": "Flow message footer" }, "action": { "name": "flow", "parameters": { "flow_message_version": "3", "flow_token": "AQAAAAACS5FpgQ_cAAAAAD0QI3s.", "flow_id": "1211462153575982", "flow_cta": "Book!", "flow_action": "data_exchange" } } } }'

Any guess what i'm doing wrong?

Send the flow........................................

Solution

  • 1. Verify permissions

    This looks like a permission error, it seems the account you used to generate the token does not have permission to this number 5731.... You can check your permissions here (replace waba & business id)

    https://business.facebook.com/settings/whatsapp-business-accounts/{waba-id}?business_id={business-id}

    To create and send flows you need these permissions "Message templates (view and manage)" & "Phone Numbers (view and manage)"

    2. Verify the request

    The field "flow_action": "data_exchange" should only be used if your flow uses an endpoint. If you flow doesn't have and endpoint then the action and payload should be like this

    "flow_action": "navigate",
"flow_action_payload": {
    "screen": "<YOUR_SCREEN>",
    "data": {
        "<CUSTOM_KEY>": "<CUSTOM_VALUE>"
    }
}

    You can also check the example request in the postman collection here
