Automate social posting with Zapier. Webhooks by Zapier, both ways.

Zapier talks to the Postbroad API with Webhooks by Zapier. A Custom Request creates a draft from any Zap, and a Catch Hook starts a Zap when Postbroad reports that a post went live or failed.

  2. Create a draft with a Custom RequestAdd a Webhooks by Zapier action, choose Custom Request, and post to /v1/posts with your key.
  3. Start Zaps from PostbroadUse a Catch Hook trigger and add its address in Postbroad as a webhook endpoint for the events you want.

  • Scheduling from Zapier takes a preview, then a schedule call with the receipt the preview returns. Creating drafts and scheduling them in Postbroad is simpler.
  • Keep the Catch Hook address private: anyone with it can start the Zap.

Workflows to start with.

Each one is a few steps. Drafts and approvals stay in Postbroad, where a person can read them.

New item in a feed, then create a Postbroad draft for LinkedIn and X.
Catch Hook for delivery.published, then log the live link in a sheet.
Catch Hook for delivery.failed, then send a message to the team.
