Webhooks allow you to subscribe to events happening on the Didomi platform to implement custom workflows when your users change their consent preferences. When users make choices on your websites, mobile apps, or preferences center, you will receive a notification allowing you to react to user choices.

When an event is triggered, we'll send a HTTP POST payload to the configured webhook endpoint. Webhooks are configured at the organization level and automatically apply to all consent events triggered within your organization, on all websites, mobile apps, or preferences center.

Configuration

Webhooks can be configured by reaching out to our support team. Provide the endpoint to send events to and, optionally, the OAuth credentials (client ID and client secret) to use.

To ensure that the consent events are received, when your endpoint is down, we retry at least five times during five minutes before moving on.

Authentication

OAuth Access Token

Requests sent to your API endpoint can be authenticated via OAuth Client Credentials grant.

The Didomi servers will authenticate against your OAuth authorization server with a Client ID and a Client Secret that you provide to obtain an Access Token.

Didomi will then call your API endpoint for sending emails with the Access Token provided in the Authorization header as a Bearer token.

IP address

API calls from Didomi will originate from the IP 35.159.1.63 . You must whitelist that IP to allow traffic from it for emails to be sent.

Payload

Events sent to your HTTP endpoints are sent as JSON-encoded objects with the following information:

Events

The payload is a JSON string in the body of the HTTP request. Examples:

{
  "type": "user.updated",
  "parameters": {
    "source": {
      "id": "unique_event_id",
      "created_at": "2019-08-07T10:45:11Z",
      ...
    },
    "old_entity": {
      "id": "didomi_user_id",
      "organization_user_id": "organization_user_id",
      ...
    },
    "new_entity": {
      "id": "didomi_user_id",
      "organization_user_id": "organization_user_id",
      ...  
    }
  }
}

{
  "type": "event.deleted",
  "parameters": {
    "entity": {
      "id": "deleted_event_id",
      "created_at": "2019-08-07T10:45:11Z",
      ...
    },
  }
}

Pending events

Pending events (with status pending_approval or similar) are always sent as event.created webhooks.

However, new pending events only generate user.created events if a new user is created as a result of a pending event. If a pending event applies to an existing user, a user.updated event is not generated as the user is not effectively modified until the event becomes confirmed.

When a pending event becomes confirmed and, assuming it contains changes that effectively modify the status of the user, then and only then a user.updated event is sent.
