Access & visibility
Allow newsletters.GetNewsletterIssue on your API key.
Workspace access by default. Private member data requires approved member delegation through Brigg-Act-As; the key supplies permissions while private ownership and project boundaries remain enforced.
Request fields
Send a JSON object with the following fields. Required fields must be included; omit optional fields you do not need.
issue_idstringRequiredUse issue_id from the selected schedule's issues. It differs from the underlying newsletter_id. newsletters.ListNewsletterIssues.
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.
