Make your first request

Run this read-only example from your Postii workspace.

Open your workspace in another tab and sign in.
Open developer tools in that Postii tab and select Console.
Copy the request below, paste it into the console, and run it.

Read-only request

const response = await fetch('/api/v1/channels/capabilities', {
  credentials: 'same-origin'
});
if (!response.ok) throw new Error('Could not load capabilities');
const { data } = await response.json();
console.table(data);

You’ll see a table of platform capabilities. This public endpoint checks API reachability; it does not confirm sign-in or a connected destination.

Check platform capabilities and validate content before saving a post.

Connect your workflow

Work with posts and connected beehiiv publications through structured requests.

Follow every result

Inspect delivery status and keep retries tied to the original request.

Available today

The workspace API runs through your signed-in browser session. External API keys and server-to-server access are not available yet. Live beehiiv delivery requires a connected publication with Send API access. Social delivery is still in development.
