Pause a campaign

Pauses a sending campaign (campaign.paused): the delivery engine takes no new delivery of it from its next look (a guard batch or a poll); the letters under way finish. A paused campaign answers as it is. Needs scope send.

Parameters

Name	In	Type	Description
`project_id`required	path	string · uuid	The project’s id
`campaign_id`required	path	string · uuid	The campaign’s id
`Idempotency-Key`	header	string 1–128 characters · pattern `^[!-~]{1,128}$`	A key of the client’s choosing, one per request it means to send once (a UUID will do). A repeat with the same key and the same body within 24 h creates nothing again and gets the first answer, marked `Idempotent-Replayed: true`. The key belongs to the API key that sent it. Only a `2xx` answer is kept: after any other answer the key is free again.

Request body

None.

401

No valid key

Problem (application/problem+json)

403

A project key without scope send (forbidden)

Problem (application/problem+json)

404

No such project or campaign in it, or another project’s (not_found)

Problem (application/problem+json)

409

The campaign is not sending (or paused), or its project is deleted (conflict); or a request with the same Idempotency-Key has not answered yet (idempotency_key_in_progress)

Problem (application/problem+json)

422

The Idempotency-Key was used in the last 24 h for another request (idempotency_key_reused), or is not 1 to 128 visible ASCII characters (validation_failed, field Idempotency-Key)

Problem (application/problem+json)

429

The key is over its rate limit, api.rate_limit_per_minute requests a minute on this node (rate_limited)

Header	Type	Description
`Retry-After`	integer	Seconds until the key’s next request passes; rounded up.

Problem (application/problem+json)

504

Postwind’s storage did not answer within its time limit (storage_timeout). A change the request makes may still take effect: check before repeating it. A repeat with the same Idempotency-Key never runs it twice: it is 409 idempotency_key_in_progress until the key’s 24 h end
