Add multiple client in Azure APIM

 Add multiple client in Azure APIM

In Azure API Management (APIM), adding multiple clients, also known as applications or subscriptions, allows different entities (such as developers or applications) to access your APIs securely. Here are the steps to add multiple clients in APIM:

### 1. **Sign in to the Azure Portal:**

   - Go to [Azure Portal](https://portal.azure.com/).

### 2. **Select your API Management Service:**

   - Navigate to your APIM instance from the Azure Portal.

### 3. **Add a New Application:**

   - In your APIM instance, go to the "Security" section.

   - Click on "Add" to create a new application.

### 4. **Fill in Application Details:**

   - Provide a unique client ID for the application. This is typically generated by the system.

   - You can set a display name for the application to identify it easily.

   - Optionally, configure other settings like product subscriptions, policies, etc.

   - Save your changes.

### 5. **Generate Client Secrets or Certificates (if necessary):**

   - Depending on your security requirements, generate client secrets or upload certificates for authentication.

   - Client secrets are typically used with confidential clients, such as server-side applications.

   - Certificates provide an additional layer of security and are used for authentication in similar scenarios.

### 6. **Configure API Access:**

   - In the application settings, configure the specific APIs, operations, or products that this application can access.

   - You can define rate limits, quotas, and policies for each application separately.

### 7. **Retrieve Client ID and Client Secret:**

   - After saving the application details, make sure to note down the generated Client ID and Client Secret. These are essential for authenticating the client application.

### 8. **Securely Store Client Secrets:**

   - If you're using client secrets, ensure that you securely store them. For security reasons, the client secret is only shown once during the creation process. Make sure to save it in a secure location.

### 9. **Implement Authentication in Client Applications:**

   - In your client applications, implement authentication using the Client ID and Client Secret or other methods like client certificates, depending on what you configured in APIM.

   - Make sure to include the necessary authentication headers or tokens in API requests made by the client applications.

By following these steps, you can add multiple clients in Azure API Management, allowing different applications or users to securely access your APIs based on the defined policies and configurations.
