Integrations for your app backend

Any backend that speaks HTTPS can connect to Limenia. For common platforms there are connectors that enforce bans directly, and runnable examples.

Request a demoSee the webhook events

  • Webhooks

    Every decision as a signed event to your backend, with retries and a delivery log.

  • Firebase

    Disable and re-enable accounts in Firebase Authentication, without keys to your project.

  • Supabase

    Ban and unban users in Supabase Auth, with a secret key used only by Limenia.

  • Flutter

    Reports through your backend, device checks with the Flutter plugin limenia_device.

  • RevenueCat

    On a ban, cancel web subscriptions and revoke promotional access as far as the stores allow.

  • Device check

    Bans that survive a reinstall: via Play Integrity and Apple DeviceCheck, without fingerprinting.

  • DSA Transparency Database

    Submit the statements of reasons for your decisions to the European Commission’s database.

Webhooks

Six events, signed with HMAC-SHA256

Limenia sends every event via POST to your backend, signed and with retries over about 20 hours. Every attempt is in the delivery log.

  • decision.created: a decision with its statement of reasons
  • subject.status_changed: a temporary suspension has ended
  • reports.resolved: the outcome for the reporters
  • appeal.resolved: an appeal has been decided
  • review.decided: a review has been decided
  • test.ping: the test from the dashboard
Examples

Runnable examples for your backend

Each example shows the same paths: send a report, query a status, check a device and receive webhooks with signature verification.

  • Node.js (Express)
  • Python (FastAPI)
  • Go
  • PHP (Laravel)
  • AWS Lambda
  • Supabase Edge Functions
  • Firebase Cloud Functions

Frequently asked questions

Do I need a connector?

No. The signed webhook covers every decision. A connector is worth it if bans should take effect directly in Firebase Authentication, Supabase Auth or RevenueCat, even while your webhook receiver is down.

Can I use Limenia without a backend of my own?

No. The API key belongs in a backend, never in a mobile or web app. A Cloud Function or an Edge Function is enough.

How do I verify a webhook signature?

Compute HMAC-SHA256 with your webhook secret over the timestamp and the raw body and compare in constant time. Reject the request if the timestamp is more than 300 seconds off. The examples on GitHub show this for every backend.
