/v1 path versions the shared API mechanics and Receivables core. Your Integration grant fixes the credit_union.v1 profile; you cannot select a profile in a request.
Optional response fields may be added without a new API version. Breaking core changes require /v2. Breaking credit-union profile changes require credit_union.v2.
Support period
PayPathIQ supports a breaking version for at least 12 months after its replacement is generally available. A security or legal requirement may require a shorter transition.Deprecation notice
For a planned breaking change, PayPathIQ publishes a dated changelog and migration guide. It also notifies the named Integration technical contact directly. API responses use the standardDeprecation and Sunset headers and link to the migration guidance.
Keep a current technical contact with your PayPathIQ Integration administrator so your team receives deprecation notices.
