Access & visibility
Allow newsletters.RunNewsletterSchedule on your API key.
Acting member required. Send Brigg-Act-As with an approved member account ID. The key supplies permissions; the member selects whose data is used.
The selected member must be active and approved by the credential. This selects whose private data is used; the credential supplies permissions. Private ownership and project boundaries still apply.
Request fields
Send a JSON object with the following fields. Required fields must be included; omit optional fields you do not need.
schedule_idstringRequiredUse schedule_id from the schedule listing. A schedule can produce multiple issues. newsletters.ListNewsletterSchedules.
At least 1 character.
Preparation, review and sending are separate
A schedule produces issues. An issue has its own issue_id; its generated content has a separate newsletter_id. Read Get newsletter issue until that content and its review_url are available. A schedule start or run response does not mean preparation has finished.
Public callers use manual approval. A person reviews and sends the issue in Brigg; preparing content or saving a draft does not send it to the audience. Send newsletter test email sends a test to the acting member, not the subscriber list.
A schedule's start_at is Unix milliseconds and its timezone is an IANA zone used for recurrence. run_now creates an extra first issue without consuming the first scheduled slot. Pause a schedule with paused: true when you want to stop future preparation while retaining the schedule.
Response
Returns 200 OK with a JSON body.
okbooleanRequiredWhether the action completed successfully.
issue_idstringRequiredIssue identifier.
newsletter_idstringRequiredNewsletter identifier.
Errors & retries
Set BRIGG_REQUEST_ID once for each logical action. The samples send it as Idempotency-Key. Reuse the same value and body on retries, including after a timeout; a missing response does not prove the action failed.
For rate limits, follow the server’s retry guidance and back off. See HTTP errors and safe retries and limits.
| HTTP status | Code | What to do |
|---|---|---|
| 400 | invalid_json |
Send a JSON object with Content-Type: application/json. |
| 400 | invalid_input |
Check the request fields and types. Supply a stable Idempotency-Key containing 1–200 characters. |
| 401 | invalid_key |
The workspace API key is missing, invalid or revoked. |
| 403 | forbidden |
Check the key’s operation and resource grants. Supply Brigg-Act-As with a member authorized by the key’s delegation grant. The selected member must be active and approved by the credential. This selects whose private data is used; the credential supplies permissions. Private ownership and project boundaries still apply. |
| 404 | not_found |
The requested operation or resource is not available to this credential. |
| 429 | rate_limited |
Wait for Retry-After before retrying. Reuse the original Idempotency-Key. |
