How to Install Twilio Connector in Mule 4

Step 1

Go to the studio palette and click the search tab and enter the connector name that you want like Twilio.

Step 2

Click the below link i.e Try looking for it in Exchange in the studio.

Step 3

Click and log in your any-point platform account it will redirect to exchange.

Step 4

Select your module and install it.

Step 5

Peruse the prompts and install the connector.

Step 6

Now, Able to look in the mule palette for activities of the Twilio connector.

Note: The underneath previews are portrayed about how to introduce Twilio connector in Mule 4.

Example for Twilio Connector in Mule4

Utilize the Twilio connector (send message operation) and send an example message to the mobile device.

Step1

Create a new Mule project on the studio as shown, namely as Twilio.

Step2

Go to the palette and drag the HTTP listener connector to get a solicitation (request) for your servers and give the host and port number. The host is localhost and the port number is 808. Test your connection and see if the port is being used or not and test it effectively.

Step3

Set the HTTP listener path as /Twilio.

Step4

Drag the data weave component to validate our Twilio details.

 Note: The beneath preview depicts the fields we need to validate and if we need to fill those fields.

Step5

Now, drag the Twilio Connector as a send message operation from the palette on the studio and click on the additional (add) configuration and give the Account SID and Auth Token qualities (values), which are accessible in the Twilio account dashboard.

Step6

Next, check the test connection. The test connection ought to be effective, as shown below.

 Next, you need to configure the below things in Twilio Connector.

Step 7

Next, we need to show the payload as a type of JSON arrangement, utilizing the data weave segment.

Step 8

Right-click on the canvas and select Run project.

Step 9

Open the Postman and hit your service URL request as shown.

Post method: http://localhost:8081/Twilio

Now, we look at the entire flow of a Mule project i.e Twilio-sample.

Note: The message you sent in the body in transform message, i.e data weave, is recieved by the mobile number that you specified.

Note: Try to use your account (Twilio) with a registered mobile number, or you won't get a message.

Twilio Body

 To: The number registered in Twilio account use that Number (+91787*******).

 From: This Number was given by Twilio (+14245*******).

 Body: “Mule-4 is on fire”.

Example

Note: Try to use Your Twilio account details in the below code, otherwise, you may get an error.

Conclusion

Mule 4 comes with a lot of improvements and enhancements i.e operations on Twilio have changed to connectors in Twilio Module. In Mule 3, there is only one connector, and we have to select an operation.
