Step 1: Verify Your Twilio Account and Phone Number

Let’s start with the basics:

1. Log in to your Twilio account and navigate to the Phone Numbers section.
2. Verify that you have a valid phone number with SMS capabilities.
3. Check that your phone number is enabled for Conversations.

Next, let’s ensure your Conversations configuration is correct:

2. Verify that Conversations is enabled for your phone number.
3. Check your Conversations settings, including the messagingServiceSid and participantIdentity.

// Example: Verify Conversations configuration using Twilio CLI

Step 3: Review Your Code and API Requests

Now, let’s review your code and API requests:

1. Check your API requests to ensure they are correctly formatted and authenticated.
2. Verify that you are using the correct Twilio API version and endpoint.
3. Review your code for any syntax errors or logical mistakes.

// Example: Send a group SMS using Twilio API

};

client.messages
  .create(message)
  .then(message => console.log(message.sid))
  .done();

Step 4: Check Message Content and Length

Let’s review your message content and length:
