What it does

Everything an AI app can do in Postfjord, your own code can do too, over the REST API: read the calendar and results, write drafts, schedule posts and work on emails. The whole API is described in one public document, postfjord.com/openapi.json, which most tools can import.

It is included from the Solo plan, and only the workspace owner can make keys.

Connect in three steps

  1. In Postfjord, open Settings, Apps and open Advanced: make a key by hand.
  2. Give the key a name, pick what it may do, and copy it. It is shown once.
  3. Send it with every request as Authorization: Bearer followed by the key, to the addresses in the OpenAPI document.

What moves where

  • From Postfjord to your code: what the key's level allows it to read.
  • From your code to Postfjord: drafts, and with the top level scheduled posts and emails.
  • A key belongs to the owner who made it. If that person leaves the workspace, their keys stop working.
