When your product depends on someone else’s API, the details matter
CodeJunction advises engineering and product leads on API contracts, webhook flows, and third-party integrations—so billing, shipping, and identity providers stay understandable under load and across releases.
What teams book us for
Short, scoped consultations and deeper reviews—always tied to a live integration or API you are shipping.
Partner API design sessions
Shape resources, error shapes, and versioning so external developers can adopt without constant support tickets.
Vendor API due diligence
Compare sandbox limits, webhook guarantees, and SLA language before you sign a multi-year contract.
Grounded in real integration work
We have sat in incident calls where a payment capture succeeded but the order service never heard about it, and in roadmap meetings where a CRM sync was blocked by ambiguous pagination. Our notes reference your OpenAPI files, Postman collections, and vendor status pages—not generic slide decks.
Read client stories from fintech, retail, and logistics teams who brought us in mid-migration.
