Overview

Publishing, editing, or deleting adverts are asynchronous operations, which means that your command is not immediately executed. When you publish an ad from your application, our platform will process it and deliver a response directly to the callback URL that you defined when you registered your app).

Here's an example of a notification you'd receive after you publish an ad:

{
  "destination": "https://myawesomeapp.com/webhooks",
  "timestamp": 1572969379247,
  "event_timestamp": 1572969379671,
  "transaction_id": "b315c893-b42c-417a-9ecd-f060cb44cf13",
  "object_id": "4f5ee709-28d7-4b68-8716-dd912157919f",
  "flow": "publish_advert",
  "data": {
    "activated_at": "2019-11-05T15:56:19.000+0000",
    "recorded_at": "2019-11-05T15:56:19.247+0000",
    "code": "active",
    "moderation": {
      "reason": null,
      "description": null
    },
    "created_at": "2019-11-05T15:56:10.000+0000",
    "visible_in_profile": true,
    "modified_at": "2019-11-05T15:56:19.000+0000",
    "ttl": "2019-11-18T17:44:04.000+0000",
    "url": "AD_ID"
  },
  "event_type": "advert_posted_success"
}

The field flow tells you what event flow this event belongs to. In this case, it's a publish_advert because you just published an ad. The event_type field gives you more details about the specific event the message refers to. This example tells you that your ad was successfully published (advert_posted_success).

For instance, when the event is a success, the data contains the following information:

Field	Description
code	The advert status code. Check Advert status codes for the list of possible codes.
ttl	The estimated time to live of the advert.
url	The URL where the advert may be seen.
created_at	The creation date of the advert on the target site.
activated_at	The activation date of the advert on the target site, if the advert was made available.
visible_in_profile	States whether the advert is visible in the user's profile: `true` or not: `false`.

On the other hand, when the event is a failure type, the data contains the following information:

Field	Description
title	The summary message of the failure
detail	The detail message of the failure
validation	The optional list of validation errors that caused the failure

Getting the advert metadata
