Save newsletter draft — Brigg developers

Access & visibility

Allow newsletters.SaveNewsletterDraft 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.

newsletter_idstringRequired

Read the issue and use its newsletter_id when available. This is the content identity, not the issue or schedule ID. newsletters.GetNewsletterIssue.

At least 1 character.

subjectstring or nullOptional

Subject line shown to recipients.

preview_textstring or nullOptional

The inbox preheader.

audienceobject or nullOptional

Selected recipients or audience definition for this newsletter.

Nested fields

Variant 1

modestringRequired

all selects all contacts; tags selects contacts carrying at least one selected tag; manual uses only the supplied email addresses.

Allowed: "all", "tags", "manual".

tagsarray of stringRequired

Stable contact tag keys. Used only in tags mode.

extraarray of stringRequired

Explicit additional email addresses. In manual mode these are the entire audience.

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.

okbooleanRequired

Whether the action completed successfully.

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.
