Bubble hands workflows a parsed webhook body, so the plugin never trusts it: every check re-reads the payment with your API key.

Questions about Bubble and Stablora
Is the Bubble app free?
Yes. The Bubble app 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 Bubble 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.
