Liddie lets your software charge customers in crypto. You create an invoice over the API, show the payer a hosted checkout (or your own), and Liddie tells you over a webhook when the money is confirmed on-chain. You don’t manage addresses, quotes, or confirmations — the platform does that for you. You just say how much you want to charge, and listen for the payment.

Accept your first crypto payment in about five minutes.

How the API works

Credentials, scopes, conventions, and rate limits — the friendly version.

The one endpoint every integration starts with.

Webhooks & IPN

Get told when you were paid instead of polling.

​
The whole integration, in four steps

1

Create an API key

In the dashboard, under Settings → API Keys. The key is shown once — keep it somewhere safe.
2

Create a payment

POST /api/v1/payments with a fiat amount. You get back a unique deposit address and a hosted invoice URL.
3

Show the payer the invoice

Redirect them to the invoice URL, or render the address yourself with the public checkout endpoints.
4

Ship when you're paid

Verify the payment.finished webhook signature, check underpaid, then release the order. Signature recipe →
