Plug-and-Play Payment Processing API
Budget: $250 – $750 USD
A complete, source-available payment-processing module is needed so it can drop straight into an existing FinTech stack via REST-style APIs.
The core must already handle credit & debit cards, popular e-wallets, standard bank transfers and AEPS rails, all in a multi-currency environment. Well-structured, documented code is essential because it will be extended in-house and audited for compliance.
Please include:
• Full source code (preferred in Node.js, Java, or Python, but any clean, well-documented stack is acceptable)
• Ready-to-consume API endpoints with request / response samples
• Database schema and migration scripts
• Step-by-step integration and deployment guide
• Postman or Swagger collection for quick testing
• Unit / integration tests that demonstrate card, wallet, bank transfer and AEPS flows across at least two currencies
• Licence terms confirming my right to modify and deploy commercially
Payment gateway credentials for live testing will be provided once the sandbox demonstration passes.
