# Heleket

> Heleket-compatible migration notes.

Use this base URL in an existing Heleket integration:

```text theme={null}
https://api.pawpayments.com/compat/heleket/v1
```

Heleket is wire-compatible with Cryptomus for the merchant API: the same paths, headers, request signing, response envelopes, and webhook signing are used.

For the supported categories and unsupported features, see [Cryptomus](./cryptomus). The only practical differences are the base URL and the invoice-level webhook format name stored by PawPayments.

For the full list of supported providers, see the [migration overview](./overview).
