Direct API {card}


Direct Card Processing API lets you process the credit and debit card deposits and payouts over REST API. In simple words, with this API the merchant will perform the card data collection on his side.

There are several transaction types supported by the API:
- {authorization} lets you receive the card payments from customers;
- {sale} lets you receive the card payments from customers;
- {payout} is a fund transfer from your merchant account to customer's card;
successful deposit;

In addition, the following webhooks are available in order to stay up-to-date with the updates asynchronously:
- Notification will be triggered each time that the transaction status changes;

{danger.fa-exclamation} IMPORTANT #1: In order to use the Direct API with full credit card details the merchant has to comply with PCI DSS and confirm their compliance level by providing the up-to-date AOC (Attestation of Compliance) document or SAQ-D with external vulnerability scan report.


{danger.fa-exclamation} IMPORTANT #2: The customer_data or customer_token must be present in the request.


{danger.fa-exclamation} IMPORTANT #3: Direct API does not support conversion, meaning that filter currency and processing currency must always match. It means the currency sent to Praxis within the Direct API sale, payout or refund call will be the same currency as we send to PSPs for processing.

We are using Cryptocurrency Prices, Portfolio, Forum, Rankings for crypto currencies, and Open Exchange Rates for FIAT currencies. The rates information is updated every 15 minutes.

Endpoints

Name URL
Sandbox (PraxisGate) https://pci-gw-test.praxispay.com/api/direct-process
Live (PraxisGate) https://gw.praxisgate.com/api/direct-process

If your CRM does not technically support two domains as the endpoints, the solution is to use one domain intead for any API calls. Sandbox: https://pci-gw-test.praxispay.com, Live: https://gw.praxisgate.com

E.g. For Live: you need to use https://gw.praxisgate.com to substitute https://gateway.praxispay.com,
as a result - https://gw.praxisgate.com/cashier/cashier.
