Every field is optional and what is left out is left alone, except `actionParams`, which replaces the delivery configuration as a whole. The delivery channel and an alert's graph cannot be changed. ## OpenAPI ````yaml PATCH /api/v1/triggers/{triggerId} openapi: 3.1.0 info: title: LangWatch API description: LangWatch openapi spec version: 1.0.0 servers: - url: https://app.langwatch.ai security: - project_api_key: [] paths: /api/v1/triggers/{triggerId}: patch: tags: - Triggers description: >- Update an automation.

The one exception is a credential the read hid: send back the `[redacted]` placeholder and the stored credential is kept (a Slack automation not yet on a connection has its stored secret moved into one), so reading an automation, changing one field and writing the whole object back is safe. Only this channel's fields are accepted; anything else is refused rather than dropped, and the rule this automation fires by belongs in `graphAlert` or `report`. anyOf: - type: object properties: members: minItems: 1 type: array items: type: string description: >- Who receives the email.
