An event-triggered callback is returned after an event is sent to Vibes. In order to determine whether or not your event succeeded or failed, you will need to understand the components of an Event Processed Callback and register to receive those callbacks.

🚧
Before you register...
Set up your endpoint before sending any callback configurations. Do not use a "fake" URL to test the configuration, as this will result in errors.

📘
What are events?
Events are primarily used for API-Triggered Messages. For more information on events and their uses, please see our Event-Triggered Messaging guide.

Callback Flow

Callback Configuration

When registering for this callback, your request body should look something like the below example.

{
  "callback_type":"event_processed",
  "event_processed": {
    "event_type": "order_shipped",
		"callbacks_to_send": "all"
  },
  "destination":{
    "url":"YOUR_DESTINATION_URL_W_HTTPS", /*Do not use a "fake" URL (such as google.com).*/
    "method":"POST",
    "content_type":"application/json"
  },
  "start_date":"2017-01-01T00:00Z",
  "end_date":"2017-02-01T00:00Z",
}

`event_type`

Using event_type, you can configure which event you'd like to receive callbacks for.

To receive callbacks for all processed events, simply remove the event_type. See example below:

{
  "callback_type":"event_processed",
  "destination":{
    "url":"YOUR_DESTINATION_URL_W_HTTPS", /*Do not use a "fake" URL (such as google.com).*/
    "method":"POST",
    "content_type":"application/json"
  },
  "start_date":"2017-01-01T00:00Z",
  "end_date":"2017-02-01T00:00Z",
}

`callbacks_to_send`

If you would only like to receive certain callback types, you can use the callbacks_to_send field to specify which callback types you'd like to receive.

all – send all callbacks (default option)
only_failures – send a callback only if something fails at any stage
routing – only routing callbacks
carrier_dlr – callback when sent to carrier + all failures (including handset failures)
handset_dlr – callback when delivered to handset + all failures

Callback Body Examples

To help you understand the body of this callback, we’ve provided examples for both successes and failures.

Routing

Success

If the event was received and the action is processing, you will see a success callback such as the one below.

 {
  "event_id":"3a083a69-2064-430a-8ab6-72f163692ed2",
  "callback_type":"event_processed",
  "event_date":"2022-08-15T20:02:36Z",
  "event_processed":{
     "event_id":"3b0e5871-d8b5-4393-b275-07ca0541c8de",
     "event_type":"day_of_delivery",
     "event_data":{
        "first_name":"Bob",
        "external_person_id":"abcd12345",
        "delivery_time":"5:00 PM",
        "order_url":"https://example.com/orders/12345"
     },
     "debug_data":{
        "field":"CUST_SYSTEM"
     },
     "action":{
        "type":"routing",
        "status":"processing",
        "status_reason":"accepted_by_event_triggered_message",
        "resource_url": "/companies/:company_key/mobiledb/event_triggered_messages/:event_triggered_message_id"
     }
  }
}

Failures

No routing rules

This indicates that the system was not able to find an action in the system (such as an Event-Triggered Campaign triggered by the event. Therefore, the system did not have an action to perform in response to the received event.

{

        }
     }
  }
}

Person doesn't belong to subscription list

This failure occurs if the person that is referenced in the event doesn’t belong to the subscription list that is associated to the event-triggered message.

              }
           ]
        }
     }
  }
}

Person not found

           ]
        }
     }
  }
}

MMS asset missing

If you are using a dynamic MMS token, this error can occur if your event did not include a URL to the intended media asset.

Dynamic media asset is not supported

If you are using a dynamic MMS token, you may receive an error if your media URL does not comply with the MMS Guidelines. Below are two examples.

If your media asset is not the correct content type:

    "event_data": {

          }
        ]

Please refer to our documentation error codes here. For status reasons, please see the below table.

status_reason	Description
`rejected`	Message was rejected by the endpoint.
`unroutable`	No delivery route could be determined for this message.
`queued`	Message is queued for delivery and waiting final confirmation.
`expired`	The message was expired and not delivered.
`other_error`	A catch-all error state for specific errors/issues that could not get classified.

Notes:

When a customer event is sent into the platform, it may generate an SMS message that is required to be split into multiple parts to send to the carrier. In cases where the message is split into parts, there will be a Carrier DLR for each part of the SMS message that was attempted to be sent to the carrier.

A Carrier DLR Callback will be generated for these scenarios:
- If an SMS message is small enough to not require splitting then there will be one Carrier DLR and in turn one Carrier DLR Callback generated indicating the success or failure of the attempted send.
- If an SMS message is large enough that it is required to be split into parts to be sent to the carrier then:
  - A Carrier DLR Callback will be generated for each part that fails to be sent to the carrier.
  - A Carrier DLR Callback indicating a successful send to the carrier will ONLY be generated for the last part that was sent to the carrier.

Handset Delivery Receipts

Notes

Handset DLRs are not available for MMS.
When a customer event is sent into the platform, it may generate an SMS message that is required to be split into multiple parts to send to the carrier and eventually to device. In cases where the message is split into parts, there will be a Handset DLR for each part of the SMS message that was attempted to be sent to the carrier.
A Handset DLR Callback will be generated for these scenarios:
- If an SMS message is small enough to not require splitting then there will be one Handset DLR and in turn one Handset DLR Callback generated indicating the success or failure of the attempted delivery to the device.
- If an SMS message is large enough that it is required to be split into parts to be sent to the carrier then:
  - A Handset DLR Callback will be generated for each part that fails to be sent to the device.
  - A Handset DLR Callback indicating a successful send to the device will ONLY be generated for the last part that was sent to the device.
