Azure API Management: 403 Forbidden Error When Using Subscription Key in Java Spring Boot Application
I'm trying to configure I've been researching this but I've hit a wall trying to I've looked through the documentation and I'm still confused about I'm sure I'm missing something obvious here, but I'm encountering a frustrating issue when trying to integrate Azure API Management with my Java Spring Boot application..... I have set up API Management to protect my API endpoints, and I'm using a subscription key to authenticate requests. However, I keep receiving a `403 Forbidden` error when I make requests to my API endpoints, even though I'm passing the subscription key correctly in the request headers. Here's a snippet of how I'm making the request: ```java import org.springframework.http.HttpHeaders; import org.springframework.http.HttpEntity; import org.springframework.http.HttpMethod; import org.springframework.web.client.RestTemplate; public class ApiService { private static final String API_URL = "https://<your-api-management-url>/api/endpoint"; private static final String SUBSCRIPTION_KEY = "<your-subscription-key>"; public void callApi() { RestTemplate restTemplate = new RestTemplate(); HttpHeaders headers = new HttpHeaders(); headers.set("Ocp-Apim-Subscription-Key", SUBSCRIPTION_KEY); HttpEntity<String> entity = new HttpEntity<>(headers); try { // This line throws 403 Forbidden error String response = restTemplate.exchange(API_URL, HttpMethod.GET, entity, String.class).getBody(); System.out.println(response); } catch (Exception e) { e.printStackTrace(); } } } ``` I have confirmed that the subscription key is valid and it has not expired. Additionally, I have checked the API Management policies to ensure that the API is configured to allow requests with a subscription key. I've also tried using Postman to make the same request with the subscription key, and it works without any issues. I've looked through the Azure portal logs and the API Management analytics, but there are no clear indications of what might be causing the 403 error. I suspect it may be related to how the Spring Boot application is configured or the way headers are being sent. Has anyone experienced a similar issue or can provide insights on what I might be missing? What's the best practice here? What am I doing wrong? For reference, this is a production REST API. Am I approaching this the right way? This is for a application running on Linux. I appreciate any insights!
