Use this base URL in an existing Heleket integration: 
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. 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.
