Two help centres, system documentation and an onboarding kit for a platform that helps dealers import cars from US auctions.
A payments API for a Nigerian fintech that doesn't exist, written to the standard we hold client work to. Five deliverables, each a different kind of documentation.
From signing up to a confirmed test payment in four steps.
Look for one task per step, test cards for every outcome, and a warning placed exactly where people make the mistake.

Look for limits stated in units, a status table that tells you what to do next, and errors paired with their fix.
Setting up an endpoint, verifying signatures and handling retries.
Look for working verification code, the security reason for checking it, and a retry schedule you can plan around.
What is stored, for how long, how it is protected and who is responsible for what.
Look for a shared-responsibility table a compliance team can lift straight into a security review.
Three releases, each change labelled added, changed, deprecated or fixed.
Look for a deprecation with a removal date, and the new parameter linked to the page that documents it.
