Off-the-shelf connectors assume both systems are modern, documented and willing to talk to each other. In practice one side is often a legacy database, a bespoke tool, or a platform whose API is rate-limited enough that calling it directly is unsafe. Bridging is the work of putting a controlled layer between the two.
When you need a bridge
- One system has no usable API — only screens, exports or a database.
- An API exists but is undocumented, unversioned, or so rate-limited that a normal integration would keep hitting the ceiling.
- A vendor system you cannot change sits between you and the data you need.
- You need a stable interface in front of something that changes often, so downstream systems are shielded from it.
What the layer does
- Normalises formats so each side sees data in the shape it expects.
- Holds a queue so a burst on one side never overloads the other, and retries failed calls with backoff that respects each API’s limits.
- Records every transaction, so a disputed record can be traced end to end.
- Isolates you from change. When one platform changes an API version, only the bridge is updated — nothing downstream moves.
Where a system has no interface at all
We work with what exists: scheduled file exchange over SFTP, a direct database connector with read models first and controlled writes second, or a documented REST wrapper we build and host on your behalf so the system integrates like any modern platform without becoming a second source of truth.
How we work
- Discovery first. We document how the awkward system actually behaves before quoting anything.
- Fixed scope, fixed price against that documentation.
- Built against a staging copy, tested with your data, handed over with a runbook.
