List Phone Numbers
List Phone Numbers lists the phone numbers registered on a WhatsApp Business Account. Use it to find a number's Phone Number ID for Send Message, or to check that a WABA ID is right and the connection can reach it.
It calls GET https://graph.facebook.com/v23.0/{wabaId}/phone_numbers.
The activity has four tabs: Configuration, Auth, Input and Output.
Configuration
| Field | Required | Description |
|---|---|---|
| Name | Optional | Name of the step, should be unique within this workflow. |
| Description | Optional | Describe the purpose or function of this step. |
| WABA ID | Optional | WhatsApp Business Account id. Not the app id or phone number id. Sent as the wabaId path parameter; Meta needs it. |
Auth
| Field | Required | Description |
|---|---|---|
| Auth Type | Optional | OAuth 2, the only option. WhatsApp uses the Meta OAuth connection. |
| WhatsApp Connection | Optional | The WhatsApp resource, which needs the whatsapp_business_management scope. |
Input
This activity is built on the REST Client. It sends no request
body. You can map pathParams.wabaId from an earlier step here.
| Field | Required | Data Type | Description |
|---|---|---|---|
| Target | Required | Object | The HTTP request. |
Output
The activity returns an httpResponse object (status.code, status.message, headers,
body). The response body carries:
| Field | Data Type | Description |
|---|---|---|
| data[].id | String | The Phone Number ID to use in Send Message. |
| data[].display_phone_number | String | The phone number as shown to recipients. |

If the call fails with error 100, subcode 33, the WABA ID is wrong or the connection
can't access that account. See Troubleshooting.
