Send a Conversation Message with the Sinch Node.js SDK

Note:

Before you can get started, you need the following already set up:

Set all Conversation API configuration settings.
Node.js and a familiarity with how to create a new app.

Learn how to quickly send Conversation messages in a Node.js application with the Sinch Node.js SDK.

Steps:

Set up your Node.js application
Send your first SMS message

Set up your Node.js application

First we'll create a Node project using npm. This creates a package.json and the core dependencies necessary to start coding.

To create the project, do the following steps:

Create a folder called send-conversation-app
Navigate into the folder you created and run the following command.
Copy

Copied
```
npm init
```
This command adds the package.json file. You will be prompted to provide values for the fields. For this tutorial, you can simply accept the default values and press enter at each stage.

You can install the Sinch Node.js SDK using either npm or Yarn:

npmYarn

Copy

Copied

npm install @sinch/sdk-core

Copy

Copied

yarn add @sinch/sdk-core

Note:

If you want to use the SDK with a javascript framework such as React or Angular, you can import it with an import statement.

Copy

Copied

import {SinchClient} from `@sinch/sdk-core`

Create your file

Create a new file named index.js in the project and paste the provided code into the file.

Modify your application

The code provided includes placeholder parameters. You'll need to update the parameters detailed in the following subsections with your values.

Note:

This sample code is configured for the US region. If your Conversation API app wasn't created in the US region, update you can set the region when you initialize the Sinch client:

Copy

Copied

const sinchClient = new SinchClient({
    projectId: "YOUR_project_id",
    keyId: "YOUR_access_key",
    keySecret: "YOUR_access_secret",
    region: Region.EUROPE
});

Initialize the client

Before initializing a client using this SDK, you'll need three pieces of information:

Your Project ID
An access key ID
An access key Secret

These values can be found on the Access Keys page of the Customer Dashboard. You can also create new access key IDs and Secrets, if required.

Note:

If you have trouble accessing the above link, ensure that you have gained access to the Conversation API by accepting the corresponding terms and conditions.

Fill in remaining parameters

Assign your values to the following parameters:

Placeholder value	Your value
`YOUR_app_id`	Find your app ID on your Sinch dashboard.
`YOUR_channel`	The channel you want to use to send the message. This guide presets this `channel` property to `SMS`, but you may update it to any channel that's already configured on your Conversation API app. You may add the following channels to your app from the Sinch Customer Dashboard: `SMS` `MESSENGER` `MMS` `RCS` `WHATSAPP` `VIBER` `VIBERBM` `INSTAGRAM` `TELEGRAM` `KAKAOTALK` `APPLEBC` `LINE` `WECHAT`
`RECIPIENT_number`	The channel identity of the recipient to which you want to send the message. When using the `SMS` channel, this will be a phone number.
`YOUR_sms_sender`	Your Sinch virtual phone number, available on the customer dashboard. This is only required if you are using the `SMS` channel.

Ensure that you save the file.

Send your first Conversation message

Now you can execute the code and send your test Conversation message.

Run the following command:

Copy

Copied

node index.js

You should receive a text to the phone number you entered and you'll see a response in your terminal or command prompt. You did it!

Next steps

The code you used in the index.js file sends a POST request to the Sinch API /Messages endpoint to send the text message. Click here to read more about the messages endpoint.
