Integrations and APIs

Making two systems that were never meant to talk exchange data reliably.

Context

Marketplace, ERP, payment gateway, CRM, spreadsheet, a legacy system nobody wants to touch. Each with its own format, its own rate limit and its own particular way of failing.

A good integration isn't the one that works on delivery day: it's the one that keeps working when the API on the other side goes down for twenty minutes, changes a field without warning, or starts throttling calls. The work is anticipating that — retrying sensibly, keeping what didn't go through, and telling whoever needs to know.

Signs this is your case

  • Marketplace orders reach the system by manual typing
  • The current integration fails silently and nobody knows how many records were lost
  • Every report means exporting from three places and joining by hand
  • You depend on a vendor for any change to the data flow

What you're left with

  • An integration with error handling, retries and a pending queue
  • A dashboard or report showing what went through and what stalled
  • Credentials isolated in a vault, never inside the code
  • Tests on the paths that usually break, not only the happy path

What it isn't

  • A single script running on somebody's machine
  • Integrating with a system whose access can't be provided

Describe the actual case. The technical answer comes in the conversation.
