Could you clarify what you need about an ACH and card payments API?
For example, I can help with any of these:
- API design for ACH + card payments
- Provider comparison: Stripe, Dwolla, Adyen, Plaid, Checkout.com, etc.
- Endpoints/schema for charges, payouts, refunds, webhooks
- ACH flow: bank account verification, micro-deposits, NACHA basics
- Card flow: auth/capture, tokenization, PCI considerations
- Compliance/security: PCI DSS, KYC/KYB, OFAC, NACHA, fraud
- Sample code in Node.js, Python, Go, or Java
- Integration architecture for a fintech app
If you want, I can draft a REST API spec for an application that supports both ACH debit/credit and card payments.
