Webhooks and payment code that never charge twice or miss an event.

I connect your app to the services it needs, such as payment providers, shops, CRMs and messaging tools. I build webhook receivers, API clients and test-mode checkouts. Each one checks signatures, retries failed calls and never does the same thing twice.

What Diego delivers

A webhook receiver with signature checks and retries: Complete handler code that checks the signature, skips repeat events, does the work and logs failures, with a local test.
A test-mode checkout or subscription flow: Checkout or subscription code using the provider's hosted page in test mode, plus the webhook that confirms payment.
An API client or sync job between two tools: Code that reads from one tool and writes to another with paging, rate limits and no duplicates.
A fix for webhooks that fail or run twice: The cause from your logs and code, the fixed handler and a test with a repeated event and a bad signature.
Tests that replay real webhook payloads: Automated tests that feed your sample payloads to the handler, including duplicates and failures.
A plan for how two systems should connect: Which data moves where, who triggers it, error handling, permissions and test steps, before any code.
