FAQ
API development & integration FAQs
How much does API development cost?
US clients pay $1,500 to $8,000 and Australian clients pay A$2,000 to A$11,000. A single connector between two systems sits at the bottom of that range; a full multi-tenant API with auth, rate limiting, and docs sits at the top. We quote fixed price after reading the API docs of every system involved.
How long does an integration take?
One to two weeks for a straightforward connector. Four to eight weeks for a complete API build. The single biggest variable is the third-party vendor: if their documentation is wrong or their sandbox is broken, the schedule slips and no amount of developer skill fixes that.
Who owns the API code?
You own it outright, including the spec and tests. We hand over the repository and can deploy it to your own cloud account so the infrastructure sits under your name.
What happens after launch?
We watch error rates and latency for the first two weeks and fix anything that surfaces. APIs also break later when a vendor changes their endpoints, so most clients keep a small monthly retainer for that.
What if a third-party API does not expose what we need?
Then we tell you before you pay for it. Some vendors have no webhook support, tight rate limits, or no sandbox at all. Those constraints change the design, so we flag them during scoping rather than after the build starts.
Can you document and version the API for other teams?
Yes. We ship an OpenAPI spec, a Postman collection, and a versioning scheme so a future change does not break existing callers. If you want a public developer portal, that is a separate quote.
