Event notification service
The Drillster event notification service provides a collection of webhooks. It offers a way for external systems to subscribe to certain events that originate in the Drillster system. As and when these events occur, subscribers are notified via an HTTP call.
Supported event notifications
The push API consists of the following notification types:
| Notification type | Description |
|---|---|
ACCOUNT_CREATED |
Fires when a new user account is created. |
GROUP_MEMBER_ADDED |
Fires as and when a member has been added to a group. |
GROUP_MEMBER_REMOVED |
Fires as and when a member has been removed from a group. |
OBJECTIVE_BECAME_NOK |
Fires when a group members is no longer compliant with an objective. |
OBJECTIVE_BECAME_OK |

Deprecated event types
There are some deprecated event types that are no longer available for new integrations.
Data format and transport
Push notifications are sent as HTTP POST or PUT requests, depending on the preference of the recipient. They contain a JSON object in the request body as payload.
The target URL is composed of a base URL, configured for the recipient, with the event name appended.
Example
POST https://www.example.com/drillster/GROUP_MEMBER_ADDED
Push messages can only be sent via https on port 443, with a valid, publicly signed, SSL certificate. Self-signed certificates are not supported. Plaintext messages (port 80) are not supported. Finally, an authentication mechanism based on basic authentication is available.
In order to guarantee a robust integration, any messages that are not properly acknowledged will be retried. Please see the documentation regarding the retry mechanism for details.
Subscribing to events
In order to make use of push notifications, you must have an event receiver set up. Please refer to the documentation for instructions.
If you require assistance in using push notifications, please contact us at support@drillster.com.
Changes and compatibility
The event types and object models will continue to be offered until an upgrade path has been communicated with all affected users. However, because of the extensible nature of the JSON file format, it is possible that additional attributes will be added to the response models without prior notice. If this happens, it will always be done in a backward-compatible way, and this documentation will be updated accordingly.
For this reason, it is important that you ensure that your integration is able to gracefully deal with previously undefined response attributes.
