Can we hit Cumulocity APIs with bootstrap credentials of microservice

Uhhh this is way too complicated for what you wanted to achieve. It’s much easier.
See here for an example using restTemplate:

Microservice SDK (java) best way to call unsupperted but available REST endpoints

I have implemented it using restTemplates: Created two pojos EventBinary and BinaryInfo: @Data public class BinaryInfo { /** * Name of the binary object. */ private String name; /** * Media type of the file. */ private String type; } @Data public class EventBinary { /** * Name of the attachment. If it is not provided in the request, it will be set as the event ID. */ private String name; /** * A URL linking to this resource. */ private String self; /** * Unique …

Just adapt that to the inventory API and you can freely define which headers are sent or not also you get the required credentials via the context service which can be autowired into your service:

@Autowired
private ContextService<MicroserviceCredentials> contextService;

headers.set("Authorization", contextService.getContext().toCumulocityCredentials().getAuthenticationString());
