The document provides an overview of Mulesoft's HTTP Connector. It describes how the connector can be used to listen for and send HTTP/HTTPS requests. It also provides a sample use case demonstrating how to configure the connector as a listener to handle incoming GET requests, transforming the payload and logging the response.

• Introduction
• Ways it works
• HTTP Listener
• HTTP Requester
• Sample Use Case
• Conclusion

3. About
The HTTP connector can send and receive HTTP and HTTPS requests given
a selected host, port and address.
Depending on your needs, you can either:
 Listen for HTTP requests
 Send HTTP requests
Through additional configuration, the connector allows you to:
 Use TLS encryption to send or receive HTTPS requests
 Send Authenticated Requests, via Basic Authentication, Digest and OAuth

4. Ways it works
In Studio, the HTTP connector can work in one of two ways, depending on
where it’s placed in a flow:
 As an HTTP Listener
 As an HTTP Requester

5. As HTTP Listener
To instantiate the connector as an HTTP listener connector, you must place it
onto a blank Anypoint Studio canvas into the Source section of a new flow (i.e.
as the first element in the flow) as you design your Mule application:

6. As HTTP Requester
To instantiate the connector as an HTTP request connector, you must place it
into the Process section of a flow (i.e. : anywhere except the beginning of it):

7. Sample Use Case
So now, we will see how http connector works as a listener:

8. Continue…
Step 1: Create a new flow httpconndemoFlow as directed below:

9. Continue…
Step 2: Configure http listener of httpconndemoFlow for GET method as:

10. Continue…
Step 3: Add a set payload transformer and a logger just after it
Value:
#['This is a sample payload']
Message:
#['LOGGER_MSG- '+message.payload]

11. Continue…
Resulting XML config would be:

12. Continue…
Now, we let’s start testing in browser
Corresponding logger message in console:

13. Conclusion
So this way we have seen how http connector works as a listener, Similarly http
requester can be configured and be used.
HTTP listener can be configured for different HTTP methods- GET, POST, etc.
