    • Direct API {apm}

    Direct API lets you use a single integration to connect with a variety of e-wallets and online banking solutions. In few easy steps you will open a direct path for your customers to pay in most convenient way with their local payment solutions.

    Currently Direct API offers the following APIs:
    - {sale} lets you receive the card payments from customers;
    - {payout} is a fund transfer from your merchant account to customer's wallet or bank account;

    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;

    Direct API is a single integration to let your customers pay with a number of alternative payment methods directly. For that reason the API call for each payment method is slightly different: it has to consider the local personal ID or e-wallet payer identity, whichever is being used by a certain payment solution.

    The wallet_data structure varies depending on the PSP and the specific APM, as each APM has its own unique way of identifying the customer. The example in the documentation is not universal;

    {danger.fa-exclamation-triangle} IMPORTANT #1: Some APM solutions do not accept some or any customer and payment details over API, meaning that the customer will be requested to enter the details at the APM's transaction details page.

    {danger.fa-exclamation} IMPORTANT #2: 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.

    {danger.fa-exclamation} IMPORTANT #3: The gateway value should be present in signature generating only if this field is present in request body.

    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.
