Everything you need to ship posts programmatically

One endpoint, three platforms

Instagram, Facebook Pages, and LinkedIn behind a single, consistent REST API. X and TikTok are on the way.

Images, carousels, reels

Publish any supported media type. HawCast handles the multi-step upload dance for you.

Schedule anything

Queue a post for any future time. A dedicated worker publishes it and never double-posts.

Webhooks

Get a signed callback the moment a post is published or fails, no polling.

Per-project API keys

Scope keys to a project, rotate anytime, with per-key rate limits.

Usage you can see

Track published posts, success rate, and quota from the dashboard or the API.

3

4

FAQ

Do I need my own Meta app?

Yes. HawCast uses a bring-your-own-app model, so you stay in full control of your access and limits. Our setup guide walks you through creating one and generating a token.

What counts as a post?

Each successfully published post (image, carousel, or reel) counts once against your monthly quota, whether it was immediate or scheduled.

What happens at my quota?

Publishing pauses until the next cycle or until you upgrade. Nothing is lost.

How far ahead can I schedule?

As far as you like. You host the media at a durable URL; HawCast fetches it at publish time.

Can I cancel anytime?

Yes. See the Billing & Refund policy for details.

Is my data safe?

Credentials are encrypted at rest and never shared. See the Privacy Policy and DPA.
