Notification Configurations API
Terraform Cloud can send notifications for run state transitions and workspace events. You can specify a destination URL, request type, and what events will trigger the notification. Each workspace can have up to 20 notification configurations, and they apply to all runs for that workspace.
Interacting with notification configurations requires admin access to the relevant workspace. (More about permissions.)
Notification Triggers
Notifications are sent as the run progresses, and can be triggered on one or more types of state transition. These are specified in the triggers
array attribute. Available triggers are:
Display Name | Value | Description |
---|---|---|
Created | "run:created" | A run is created and enters the Pending stage |
Planning | "run:planning" | A run acquires the lock and starts to execute. |
Needs Attention | "run:needs_attention" | A plan has changes and Terraform requires user input to continue. This input may include approving the plan or a policy override. |
Applying | "run:applying" | A run enters the Apply stage, where Terraform makes the infrastructure changes described in the plan. |
Completed | "run:completed" | A run completes successfully. |
Errored | "run:errored" | A run terminates early due to error or cancellation. |
Drifted | "assessment:drifted" | Terraform Cloud detected configuration drift. This option is only available if you enabled drift detection for the workspace. |
Checks Failed | "assessment:check_failure" | One or more continuous validation checks did not pass. This option is only available if you enabled drift detection for the workspace. |
Health Assessment Failed | "assessment:failed " | A health assessment failed. This option is only available if you enable health assessments for the workspace. |
Notification Payload
The notification is an HTTP POST request with a detailed payload. The content depends on the type of notification.
For Slack and Microsoft Teams notifications, the payload conforms to the respective webhook API and results in a notification message with informational attachments. Refer to Slack Notification Payloads and Microsoft Teams Notification Payloads for examples. For generic notifications, the payload varies based on whether the notification contains information about run events or workspace events.
Run Notification Payload
Run events include detailed information about a specific run, including the time it began and the associated workspace and organization. Generic notifications for run events contain the following information:
Name | Type | Description |
---|---|---|
payload_version | number | Always "1". |
notification_configuration_id | string | The ID of the configuration associated with this notification. |
run_url | string | URL used to access the run UI page. |

workspace_id | string | ID of the run's workspace. |
workspace_name | string | Human-readable name of the run's workspace. |
organization_name | string | Human-readable name of the run's organization. |
notifications | array | List of events which caused this notification to be sent, with each event represented by an object. At present, this is always one event, but in the future Terraform Cloud may roll up several notifications for a run into a single request. |
notifications[].message | string | Human-readable reason for the notification. |
notifications[].trigger | string | Value of the trigger which caused the notification to be sent. |
notifications[].run_status | string | Status of the run at the time of notification. |
notifications[].run_updated_at | string | Timestamp of the run's update. |
notifications[].run_updated_by | string | Username of the user who caused the run to update. |

Sample Payload
Notification Authenticity
If a token
is configured, Terraform Cloud provides an HMAC signature on all "generic"
notification requests, using the token
as the key. This is sent in the X-TFE-Notification-Signature
header. The digest algorithm used is SHA-512. Notification target servers should verify the source of the HTTP request by computing the HMAC of the request body using the same shared secret, and dropping any requests with invalid signatures.
Sample Ruby code for verifying the HMAC:
Notification Verification and Delivery Responses
When saving a configuration with enabled
set to true
, or when using the verify API, Terraform Cloud sends a verification request to the configured URL. The response to this request is stored and available in the delivery-responses
array of the notification-configuration
resource.
Configurations cannot be enabled if the verification request fails. Success is defined as an HTTP response with status code of 2xx
.
Configurations with destination_type
email
can only be verified manually, they do not require an HTTP response.
The most recent response is stored in the delivery-responses
array.
Each delivery response has several fields:
Name | Type | Description |
---|---|---|
body | string | Response body (may be truncated). |
code | string | HTTP status code, e.g. 400 . |
headers | object | All HTTP headers received, represented as an object with keys for each header name (lowercased) and an array of string values (most arrays will be size one). |
sent-at | date | The UTC timestamp when the notification was sent. |
successful | bool | Whether Terraform Cloud considers this response to be successful. |
url | string | The URL to which the request was sent. |
