Webhook Configuration +In Merlin's yaml for config you can add new field for the webhook's configuration which will looks like this: +```yaml +WebhooksConfig: + Enabled: true + Config: + on-model-version-deployed: + - URL: http://127.0.0.1:8000/async-webhook + Method: POST + Async: true + Name: async + on-model-version-undeployed: + - URL: http://127.0.0.1:8000/sync-webhook + Method: POST + FinalResponse: true + Name: sync +``` +## 2. Webhook Events and Payload +### 2.1. Model Version's Endpoint +**Events:** +- `on-model-version-predeployment`: will be triggered before the version endpoint is deployed, if the sync webhook return an error (non `200` response), the deployment will be **aborted**. The successful response of this webhook will not affect the deployment process, as we do not process the response +- `on-model-version-deployed`: will be triggered after the version endpoint is successfully deployed (either new or updated) +- `on-model-version-undeployed`: will be triggered after the version endpoint is successfully undeployed + +**Request Payload** +```json +{ + "event_type": "{event type}", + "version_endpoint": "{version endpoint object}" +} +``` + +Examples: +```json +{ + "event_type": "on-model-version-predeployment", + "version_endpoint": { + "id": "3fa85f64-5717-4562-b3fc-2c963f66afa6", + "version_id": 0, + "status": "pending", + ... + } +} +``` + +For the the complete field `version_endpoint` please refer to our [swagger docs](https://github.com/caraml-dev/merlin/blob/main/swagger.yaml). + +**Response** + +As of writing this document (25 September 2024) and mentioned previously, the successful response will not affect the process of our deployment. But for future usage, we're expecting the response of the final synchronous webhook that will be called to be in the following format: + +Successful Response: +```json +{ + "code": "200", + "version_endpoint": "{version endpoint object}" +} +``` + +Error response: +```json +{ + "code": "{error code}", + "message": "{reason for error}" +} +``` \ No newline at end of file
