Subscribe Send the body below to Import Subscription . You only need to change:
url(required) - Located under data.actions[0].params.url. Replace {{yourWebhookURL}} with the destination URL that should receive the events.asStatus"active" to enable the subscription immediately, or "inactive" to save it as an inactive revision.

A 201 response returns your new subscription - save its _id to manage it later. You can also add an optional authorUid root field (a Texter user UID) to attribute the subscription to a specific user.
Payload When the event fires, your URL receives an HTTP POST with eventName: "messageFailed" and the following eventData:
The chat associated with the failed message. See the Chat object for all fields. The error message or code received from the provider.
When the failure occurred (Unix epoch milliseconds).
Unique IDs assigned to the message(s) by the external provider (e.g. WhatsApp wamid...).
{ "eventName" : "messageFailed" , "eventData" : { "chat" : { "_id" : "69072b0233aea8a47f8bad9f" , "hasMessageError" : true , "title" : "972521234567" , "..." : "..." }, "error" : "Message undeliverable \n Message Undeliverable." , "timestamp" : 1768141074000 , "externalId" : [ "wamid.HBgMOTcyNTIxMjM0NTY3FQIAERgSMDhGRTVGNEY1MTA0Q0NBMzNEAA==" ] } }
How to identify the message Because this event is triggered by the external provider (e.g. Meta/WhatsApp), the payload does not contain the internal message._id. Instead, it provides the externalId. To find the specific message in your system:
Take the _id from the chat object in the payload.
Call Get Messages of a Chat .
Find the message whose channelInfo.id matches one of the values in the externalId array.
