How do I install the OmniSocials Java SDK?

The Java SDK is not on Maven Central yet. Clone the v0.9.0 tag from github.com/OmniSocials/omnisocials-java and build it with mvn install. It needs Java 11 or later and depends only on Jackson.

How do I post to Instagram, LinkedIn or X with Java?

Connect the accounts once in the OmniSocials app. Then create the client with OmniSocials.fromEnv() and call client.posts().create() with the content, the channels and the time to post. Leave out the time and the post stays a draft for your team.

Does the Java SDK support async code?

The Java client is synchronous and built on the JDK HttpClient. Call it from your own executor when you need work in parallel.

How do I verify OmniSocials webhooks in Java?

Pass the raw request body, the X-OmniSocials-Signature header and your webhook secret to Webhooks.verifySignature(). It checks the HMAC-SHA256 signature with a constant-time compare, rejects deliveries older than 5 minutes and returns the parsed event.

What happens when my Java code hits the rate limit?

The API allows 100 requests per minute per key. The SDK retries 429 responses, server errors and dropped connections twice by default and waits for Retry-After. If the limit still holds, it throws RateLimitException with the time to wait.

Do I need my own developer app for each platform?

No. You connect each account once in the OmniSocials app with the platform's own sign-in (Telegram: press Start in the OmniSocials bot; Discord: Continue with Discord, or paste a webhook URL). After that, every API key of the workspace can post to it. The SDKs and the API do not connect accounts themselves.

Is there a sandbox or test mode?

No, there are no test keys. Leave out scheduled_at and a post stays a draft, so you can build against a real workspace without publishing. Many teams also keep a separate workspace with test accounts.

The SDKs are free and open source. They need an API key, which comes with every OmniSocials plan: $10 per seat per month billed annually, or $12 billed monthly. You can try it for 14 days first.
