This document describes creating a web application in MuleSoft that allows users to send SMS messages through RingCentral APIs. The web application takes user input for the "To" number, "From" number, and message text. When submitted, it calls a Mule API that authenticates with RingCentral, gets an access token, and uses the RingCentral messaging API to send the SMS. The Mule application then displays a success response page back to the user with the message ID.

- 2. We have seen in our previous post the way of integrating RingCentral with MuleSoft and sending SMS messages by consuming RingCentral APIs. This post we will create a small web application in MuleSoft using HTML pages that will be calling RingCentral APIs and will be send SMS.
- 3. In Anypoint Studio IDE, after we create a new MuleSoft project, we will be creating HTML that will be providing the interface to the users and take the input.
- 4. Let's create the following HTML page in our Mule project:
- 5. As we see, we are taking 3 visual input (To, From, Text Message) from user in HTML form. The user here will put the phone number where the message will be send as well as the phone number from which the message will be send. The 3rd parameter message will take the input SMS message from users. We can also see, once the form is submitted by users, it will call an Mule API.
- 6. Next steps will be design the Mule flows that will expose the Mule API and will be called internally by the user from the web portal. The main task of this Mule API will be calling RingCentral Authentication API first, get the access_token from /restapi/oauth/token API , and then call the messaging API of RingCentral to send SMS.
- 8. Here we can see, the main flow is using parse template component to host HTML page in form of web application. Once the submit button is clicked by users, the input payload will arrive at SendSMS flow, where it will call RingCentral Authentication API to get access_token and then use this token while calling messaging API of RingCentral next to send the SMS message. The OAuth token flow is kept under Cache to avoid multiple call to the RingCentral authentication API before the access_token expires.
- 9. Finally, at the end we need to design our response web application HTML page to show the successful response message to the web application users:
- 10. Here we are showing the successfully message send response along with message id.
- 12. Once the web application is deployed in server, we can start our Mule web application as follow:
- 13. The web application is asking the users to fill the web form with phone number from which the SMS will be send and the number where the message will be delivered. It also provide the user the visual field to enter their input SMS text.
- 14. Once users hit submit button, we will see the response from the web application:
- 15. As we can see, the message is send successfully using back-end RingCentral messaging API leaving the user with above response. The response will display unique message id each time users send a SMS with successful response.
