Every Beehiiv action and event your agent gets out of the box.

Create Segment

Create an audience segment from explicit subscription IDs, explicit emails, or custom-field rules; returns the segment and its initial calculation status.

Create Subscription

Create a new publication subscription without reactivating an unsubscribed address or sending a welcome email; supports attribution, initial custom fields, and newsletter-list assignment.

List Custom Fields

List the custom-field definitions available for subscriber metadata and dynamic audience segments in a publication, returning one page controlled by page and limit with pagination metadata for retrieving additional fields.

List Posts

Search a publication's posts by status, audience, channel, slug, tags, or author and optionally include content, recipients, or statistics.

List Publications

List publications accessible to the API key, optionally including publication statistics; use the returned publication IDs with publication-scoped tools.

List full subscriber records currently included in an audience segment, optionally including stats, custom fields, referrals, tags, or premium tiers.

List Segments

List audience segments in a publication, filtered by segment type or calculation status, with optional latest statistics.

List Subscriptions

Search a publication's subscriptions by exact email or filter by status and tier, returning one cursor-controlled page of subscriber records.

Update Draft Post

Update content or presentation settings on an existing draft after verifying it is still a draft; refuses confirmed, archived, or sent posts and cannot publish or schedule.

Update Subscription Custom Fields

Set or remove custom-field values on one subscription without changing its email, tier, billing link, or subscribed status.
