A fintech SDK runs inside another organization's application. Define protection coverage, data responsibilities and failures through an explicit integration contract.
Evaluation approach
Separate SDK signals, host responses and server authorization. Document error codes, supported versions, data fields and conflicts. Unconditional host termination can have substantial product effects.
Application example
A payment SDK can stop the affected operation and return a clear error. The host presents retry or support, while server transaction identifiers control duplicate initiation.
Limits and considerations
Compatibility with another security product is not automatic. Test processing order and runtime interactions.
Checks and decisions
- Publish event and error contracts
- Describe data fields
- Test host combinations
Make protection behavior part of the integration contract so customers understand which functions are restricted and when.
