Frequently asked questions
Does it include TypeScript types?
Yes — type definitions ship inside the package, so you get autocomplete and type-checking out of the box.
Is the API promise-based?
Every method returns a promise, so you can use async/await throughout.
How do I read the raw body for webhook verification?
Capture the raw request body (e.g. express.raw()) before JSON parsing, since the signature is computed over the exact bytes CryptoPayr sent.
Where are the full examples?
The API documentation covers payments, payouts, refunds, balances and live rates with Node samples.
