Aurumsys API
Accept payments and send payouts through one API. Start with the integration guide, then keep the reference open while you build.
Integration guideAuthentication, idempotency, the hosted payment page, callback signature verification, statuses, cascading, refunds, errors and rate limits.
API referenceEvery endpoint, field, status code and callback event, from the OpenAPI description.
FlowThe payin, payout and refund journeys drawn step by step: who calls whom, what happens inside every request, and where a transaction can end up.
For tools and agents
Every page on this site is also served as Markdown at the same address with
a .md extension, and /llms.txt
indexes the lot.
