- [Get Notification](https://docs.meetecho.ai/api-reference/notifications/get.md)
- [List Notifications](https://docs.meetecho.ai/api-reference/notifications/list.md)
- [Trigger Notification](https://docs.meetecho.ai/api-reference/notifications/trigger.md): Initiates an outbound voice call to the customer's primary phone.

- [Create Webhook Endpoint](https://docs.meetecho.ai/api-reference/webhooks/create.md): Registers a new HTTPS endpoint for the project. Echo generates a signing secret automatically — save it from the response.

- [List All Project Deliveries](https://docs.meetecho.ai/api-reference/webhooks/deliveries/list-project.md): Returns deliveries across all endpoints for the project, newest first.
- [Retry Failed Delivery](https://docs.meetecho.ai/api-reference/webhooks/deliveries/retry.md): Manually triggers an immediate retry for a `failed` delivery. The new attempt is recorded with `triggered_by: "manual"`. Manual retries do not count against the automatic retry limit and can be triggered as many times as needed.

- [Introduction](https://docs.meetecho.ai/index.md): Echo is an AI-powered voice notification platform. One API call initiates a real phone call that can hold a full conversation with your user.
- [Quickstart](https://docs.meetecho.ai/quickstart.md): Sign up, create an agent, and send your first voice notification in five steps.
