Most relevant headers including the `X-Cumulocity-Application-Key` header are controlled through the context. So in order to change or remove a header you’ll have to create a new context and run your request within it.

The context is managed through `com.cumulocity.microservice.context.ContextService<C>` I don’t have a concrete example that I can share but here is a basic approach that you can take:

1. Inject `ContextService<MicroserviceCredentials>` into your bean
2. Get the current context from it using the `contextService.getContext()` method
3. Clone this context without the application key
4. Enter this modified cloned context using `contextService.runWithinContext()`
5. Execute your desired requests using `MeasurementApi` or `InventoryApi` within the supplied `Runnable`
