Integration should have a clear owner and purpose
An integration is useful when it removes controlled duplicate work or makes approved information available where a decision is made. Before development, both systems, authentication options, data ownership and failure behavior must be reviewed.
Integration work can include
- REST APIs for web and mobile applications
- Authentication, permissions and rate controls
- Validated data exchange between approved systems
- Webhooks, scheduled synchronization and audit logs
- Error handling, retry rules and monitoring requirements
Security and support are part of the interface
Credentials should not be exposed in public code or browser storage. The written scope should identify which party controls each service, any provider limitations and how integration changes will be maintained.
