Payment gateway and partner API integration
I connect your product to payment partners so money movement is reliable: idempotent requests, safe retries, webhook handling and reconciliation that does not need a spreadsheet.
Tell me about your projectWhat you get
- Secure integration with your payment or banking partner, tested against every API contract
- Idempotency, retry and timeout handling so failures never double-charge
- Automated reconciliation to cut manual finance work
- Performance tuning so the integration stays fast at peak load
- Documentation and a walkthrough for your team
Good fit if you need
- Adding a payment gateway to a new or existing product
- Replacing a slow or fragile partner integration
- Automating settlement and reconciliation reports
Common questions
Which payment partners can you integrate?
Any partner that exposes an API. The approach is the same: read the contract, build against it with tests, and handle failure cases explicitly. Share the partner docs in the contact form and I will confirm scope.
How do you prevent duplicate payments?
Every payment request carries an idempotency key, retries are safe by design, and webhooks are deduplicated before they touch your records.
Can you fix an integration that already exists?
Yes. I start with a review of what is failing or slow, send a short plan, then ship fixes in small tested increments.
