Internal ID: MTM-66671
Description
The deprecation of attaching microservices’ tenant options as request headers by the microservices proxy was under Public Preview, and is now Generally Available (GA) for CD versions 2026.230.0 and higher, and will be present in the 2027 annual release.
Until now, tenant options were attached to each microservice request unless this functionality was explicitly disabled via a feature toggle. The microservice proxy added the tenant options to the request headers and forwarded the request to the respective microservice. This functionality is now disabled by default. Tenant options are no longer attached as headers to requests to microservices. The retrieval of the tenant options remains possible through the endpoint <TENANT_DOMAIN>/application/currentApplication/settings.
This change is now available by default.
Caution
Migration from Public Preview to General Availability - action required.
If you are relying on the attachment of tenant options as headers to the microservice requests, you need to change this behaviour respectively for cumulocity core CD versions higher than 2026.230.0 and 2027 annual release.
