In your springboot application , if you want to pass a JWT token to another REST api, the general approach is to pass it through headers. In your springboot application, you could configure your rest template bean to include the JWT token in every request from your application.For instance , you could create a rest template bean like :

@Configuration
public class RestTemplateConfig {

  @Bean
  @RequestScope
  public RestTemplate authTokenAddedRestTemplate(HttpServletRequest inReq) {

    final String authHeader = 
      inReq.getHeader(HttpHeaders.AUTHORIZATION);
    final RestTemplate restTemplate = new RestTemplate();

    if (authHeader != null && !authHeader.isEmpty()) {

      restTemplate.getInterceptors().add(
        (outReq, bytes, clientHttpReqExec) -> {
          outReq.getHeaders().set(
            HttpHeaders.AUTHORIZATION, authHeader
          );
          return clientHttpReqExec.execute(outReq, bytes);
        });
    }
    return restTemplate;
  }
}

Then you could use the same rest template bean everywhere. Another approach is provided here : Propagate HTTP header (JWT Token) over services using spring rest template
