Initiating A Payment

Send a POST request to /api/v1/payments/apm with:

• apmPayload — the payment method and type (see APM Payload References for all supported values)
• checksum — HMAC-SHA256 signature of accountId | amount | currency | requestId (see Checksum Authentication)
• Standard fields: requestId, accountId, amount, currency, billingDetails, device, order, callbackUrl

Amount format: Send amount as a decimal string (e.g. "100.00"). Use the exact same string when computing the checksum — do not convert to minor units.

See POST /api/v1/payments/apm for the full request schema including all billingDetails, device, and order fields.
