--- layout: docs page_title: Consul-Terraform-Sync Tasks API description: >- Consul-Terraform-Sync Tasks API --- # Tasks The `/tasks` endpoints interact with the tasks that Consul-Terraform-Sync (CTS) is responsible for running. If you [run CTS with high availability enabled](/consul/docs/nia/usage/run-ha), you can send requests to the `/tasks` endpoint on CTS leader or follower instances. Requests to a follower instance, however, return a 400 Bad Request and error message. The error message depends on what information the follower instance is able to obtain about the leader. Refer to [Error Messages](/consul/docs/nia/usage/errors-ref) for more information. ## Get Tasks This endpoint returns information about all existing tasks. | Method | Path | Produces | | ------ | ------------------- | ------------------ | | `GET` | `/tasks` | `application/json` | ### Response Statuses | Status | Reason | | ------ | ---------------------------------------------------- | | 200 | Successfully retrieved and returned a list of tasks | ### Response Fields | Name | Type | Description | | ------------ | ------------- | ---------------------------------------------------------------------------------- | | `request_id` | string | The ID of the request.
