Choose an API Contract for Two Mobile Apps
Android and iOS teams each interpret an endpoint differently. This guide gives you a small, testable way to approach the issue before changing a live system.
A practical workflow
- Document field types, nullability, pagination and error codes in one contract.
- Run contract tests with both clients before changing server responses.
What to check
Coordinate a deprecation period for fields already used by released app versions. Compare the result with the original problem and record what changed. If a measurement or test does not support the change, revisit the assumption rather than adding more complexity.
Keep the experiment small enough to reverse. Document the starting state, the change and the result so another person can repeat the process. Product menus and versions can change, so check the current documentation for your environment.
