Mulesoft HTTPS for REST API


Mulesoft HTTPS for REST API

Securing a MuleSoft REST API with HTTPS involves configuring an HTTPS listener and obtaining an SSL/TLS certificate to enable encrypted communication. Here are the steps to configure HTTPS for a MuleSoft REST API:

  1. Obtain an SSL/TLS Certificate:

    • Acquire an SSL/TLS certificate from a trusted certificate authority (CA). You can purchase one or obtain a free certificate from Let’s Encrypt.
    • Make sure to obtain both the certificate file (usually in PEM or CRT format) and the private key file (usually in PEM format).
  2. Store the Certificate and Key Files:

    • Store the SSL certificate and private key files in a secure location on the server where MuleSoft is running. For this example, let’s assume you store them in a directory called /path/to/ssl.
  3. Configure the HTTPS Listener:

    • Open your Mule project in Anypoint Studio.
  4. Add or Modify the HTTP Listener:

    • In your Mule flow, add an HTTP Listener or modify an existing one to use HTTPS.
    • Configure the listener to use the HTTPS protocol and provide the following information:
      • Hostname: The hostname or IP address where your API will be accessible.
      • Port: The HTTPS port (usually 443).
      • Path: The path to your API endpoint.
      • TLS/SSL: Enable TLS/SSL.

    Example HTTPS listener configuration:

    <http:listener-config name="HTTPS_Listener_Config" host="" port="443" basePath="/api" doc:name="HTTP Listener Configuration" protocol="HTTPS"> <tls:context> <tls:key-store path="/path/to/ssl/keystore.jks" password="keystore_password" keyPassword="key_password"/> </tls:context> </http:listener-config>
    • Replace /path/to/ssl/keystore.jks with the path to your Java KeyStore (JKS) file that contains your SSL certificate and private key.
    • Replace keystore_password with the password for the keystore.
    • If you have a separate key password, replace key_password with the key password. If not, use the same password as the keystore.
  5. Configure the HTTP Listener Reference:

    • In your HTTP listener component, reference the HTTPS listener configuration you created in the previous step.


    <http:listener config-ref="HTTPS_Listener_Config" path="/resource" allowedMethods="GET,POST" doc:name="HTTP"/>
  6. Test Your Secure API:

    • Deploy your Mule application.
    • Access your API using the https:// protocol (e.g., https://hostname/api/resource).
    • Ensure that your browser or API client recognizes the SSL/TLS certificate and establishes a secure connection.
