Twilio is a cloud communications platform that enables developers to programmatically send and receive SMS, make and receive phone calls, and perform other communication functions using its web service APIs. It is widely used in applications to facilitate seamless communication with users.
When using Twilio's SMS API, you might encounter the error code 21413. This error indicates that the 'To' phone number provided in your API request is not a valid short code. Short codes are special telephone numbers, typically shorter than regular phone numbers, used to send SMS and MMS messages.
Error 21413 occurs when the recipient's phone number in your API request is not formatted as a valid short code. This can happen if the number is incorrectly entered or if a regular phone number is mistakenly used in place of a short code.
To resolve this error, follow these steps:
Ensure that the 'To' number in your API request is a valid short code. You can check the validity of a short code by consulting the Twilio Short Codes Documentation.
Make sure that the short code is provisioned and active in your Twilio account. You can verify this by logging into your Twilio Console and navigating to the Short Codes section.
Update your API request to include the correct short code. Here is an example of a properly formatted API request using a short code:
{
"To": "12345",
"From": "+1234567890",
"Body": "Hello, this is a test message."
}
By ensuring that the 'To' number is a valid short code and correctly formatted, you can effectively resolve Error 21413. For further assistance, refer to the Twilio Error Code Documentation for more detailed information on handling errors.
