API integration
A documented, testable connection between systems with authentication and failure handling.
API contract · Authentication boundary · Data mapping · Integration tests
Diagnose · Repair · Improve · Launch · Maintain
When the product already exists, the useful work is often finding the exact failure, connecting the missing system, or preparing a launch—not starting again from a blank file.
What matters
Sunlit Logic scopes technical work before promising the outcome. External dependencies, missing access or uncertain production state stay visible rather than becoming confident guesses.
Who it is for
Teams with a live product that is failing, incomplete, disconnected from another system, or not ready to ship.
Likely project shape. A bounded diagnosis and repair, an API or payment integration, or a deployment and launch checklist.
What we deliver
Every project is scoped before work begins. This is a capability range, not a claim that every item belongs in every engagement.
Verification
We promise the agreed deliverables and the checks attached to them. Revenue, rankings, lead volume and customer behaviour stay outside that boundary.
