Notification Configurations API

Terraform Cloud can be configured to send notifications for run state transitions. The configuration allows you to 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 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 has completed successfully.
Errored	`"run:errored"`	A run has terminated early due to error or cancellation.

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	Currently always "1".
`notification_configuration_id`	string	ID of the configuration which defined this notification.
`run_url`	string	URL used to access the run UI page.
`run_id`	string	ID of the run which triggered this notification.
`run_message`	string	The reason the run was queued.
`run_created_at`	string	Timestamp of the run's creation.
`run_created_by`	string	Username of the user who created the run.
`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.

      "run_updated_by": "sample-user"
    }
  ]
}

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:

token = SecureRandom.hex
hmac = OpenSSL::HMAC.hexdigest(OpenSSL::Digest.new("sha512"), token, @request.body)
fail "Invalid HMAC" if hmac != @request.headers["X-TFE-Notification-Signature"]

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 or not Terraform Cloud considers this response to be successful.
`url`	string	The URL to which the request was sent.

Create a Notification Configuration

POST /workspaces/:workspace_id/notification-configurations

Parameter	Description
`:workspace_id`	The ID of the workspace to list configurations for. Obtain this from the workspace settings or the Show Workspace endpoint.

Status	Response	Reason
201	JSON API document (`type: "notification-configurations"`)	Successfully created a notification configuration
400	JSON API error object	Unable to complete verification request to destination URL
404	JSON API error object	Workspace not found, or user unauthorized to perform action
422	JSON API error object	Malformed request body (missing attributes, wrong types, etc.)

Request Body

This POST endpoint requires a JSON object with the following properties as a request payload.

Properties without a default value are required.

If enabled is set to true, a verification request will be sent before saving the configuration. If this request receives no response or the response is not successful (HTTP 2xx), the configuration will not save.

Key path	Type	Default	Description
`data.type`	string		Must be `"notification-configuration"`.
`data.attributes.destination-type`	string		Type of notification payload to send. Valid values are `"generic"`, `"email"`, `"slack"` or `"microsoft-teams"`.
`data.attributes.enabled`	bool	`false`	Disabled configurations will not send any notifications.
`data.attributes.name`	string		Human-readable name for the configuration.
`data.attributes.token`	string or null	`null`	Optional write-only secure token, which can be used at the receiving server to verify request authenticity. See Notification Authenticity for more details.
`data.attributes.triggers`	array	`[]`	Array of triggers for which this configuration will send notifications. See Notification Triggers for more details and a list of allowed values.
`data.attributes.url`	string		HTTP or HTTPS URL to which notification requests will be made, only for configurations with `"destination_type:"` `"slack"`, `"microsoft-teams"` or `"generic"`
`data.relationships.users`	array		Array of users part of the organization, only for configurations with `"destination_type:"` `"email"`

Update a Notification Configuration

PATCH /notification-configurations/:notification-configuration-id

Parameter	Description
`:notification-configuration-id`	The id of the notification configuration to update.

If the enabled attribute is true, updating the configuration will cause Terraform Cloud to send a verification request. If a response is received, it will be stored and returned in the delivery-responses attribute. More details in the Notification Verification and Delivery Responses section above.

Status	Response	Reason
