Postreo for Developers
Put social publishing inside whatever you're building
Your app, your AI agent or your automation workflow: a REST API and signed webhooks let it draft, schedule and publish posts through Postreo, on every network you connect.
Sound familiar?
The part of social media nobody signed up for
An API for every network
Every network has its own auth flow, media upload, character limits and review process, and each one changes without warning.
Tokens that quietly expire
Refreshing OAuth tokens and reconnecting accounts is plumbing you have to build, monitor and keep working for every user.
Publishing isn't a single request
Scheduling, retries, partial failures across networks and knowing when a post went live all need a system around them.
Built for Developers
How Postreo helps
One API for every network
Create a post once with a list of channels. Each network's own rules and limits are checked for you, the same way as in the app.
Learn moreDraft, schedule, queue or publish now
One action field decides: save a draft for review, send at a set time, take each channel's next free slot, or post right away.
Learn moreKnow when it's live
Signed webhooks tell your system when a post publishes, with the live URL, or when it fails, with the reason. Failed deliveries retry with backoff.
Learn moreKeys you can scope and revoke
Give each integration its own key with only the scopes it needs, an optional expiry date, and revoke it on its own when you're done.

How it works
From key to first post in minutes
Create a key
In Settings, create an API key with the scopes your integration needs, then call GET /me to check it works.
Post from your code
List the workspace's channels, upload media if you have any, and create a post with the channels and an action.
Listen for the result
Add a webhook URL and verify each request's HMAC-SHA256 signature. The post.published and post.failed events tell you how it went.
Networks
Every network, one API
Accounts are connected in the app once. Your code posts to them by channel id, whatever the network.
