How to set up FOSSBilling

  1. 1Download the ZIP and extract it into your FOSSBilling root (it adds library/Payment/Adapter/Stablora/ and public/gateways/stablora.png).
  2. 2In FOSSBilling open System → Payment gateways → New payment gateway, install Stablora and note its id in the URL.
  3. 3In Stablora create a Payments only API key and add the webhook endpoint https://your-billing.com/ipn.php?gateway_id=<id>; copy its signing secret.
  4. 4Paste the key and the secret in the gateway, tick Enabled and Allow one time payments, and save.

FOSSBilling answers webhooks before processing them, so Stablora cannot retry a failed one. The client’s return re-checks the payment, and failed deliveries stay under Invoices → Transactions for Process.

Tested against FOSSBilling stand-ins and a real Stablora; try it on a staging install first.

Try it first with a test key and free testnet coins — see the testing guide. The full guide is the README.md inside the download.

Questions about FOSSBilling and Stablora

Is the FOSSBilling plugin free?

Yes. The FOSSBilling plugin is free to download. Stablora charges 0.5% per incoming payment and nothing else — no monthly or setup fee.

Which coins can customers pay with?

USDT on TRON, Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, Avalanche and Solana; USDC on the same EVM networks, Base and Solana; plus BTC, ETH, SOL, TRX, BNB, POL, AVAX, LTC, DOGE, XMR and the meme coins SHIB, PEPE, BONK and WIF. They choose the coin and network on the Stablora payment page; the amount is locked when they choose it.

When is an order marked paid?

Only after Stablora confirms the payment on the blockchain and the FOSSBilling side verifies the signed webhook and re-checks the payment status with the API. A browser redirect alone never marks anything paid.

Can I test it before taking real payments?

Yes. A test API key (qk_test_…) works on public testnets with free faucet coins, so you can run the whole flow before switching to a live key. See the testing guide.

Where does the money go?

Into your Stablora balance, per network and asset. You withdraw to your own wallet from the dashboard, manually or automatically, and can have coins converted to USDT or USDC on supported networks.
