Contracts
Determine which fields, events and error codes are part of a stable integration version.
Developer Center · API lifecycle
Verify integrations without surprises.
Treat response fields, event names and behavior as integration contracts. Breaking changes should be visible, plannable and testable.
Deprecation
Plan migration and communication before an old variant is no longer supported.
Compatibility
Prevent unexpected breaking changes within the same version and make extensions backward compatible where possible.
Regression tests
Turn contract and chain tests at SDK-, API and dependency upgrades.
