60227: The selected channel for template is not supported

This error occurs when you create or use a Verify template with a delivery channel that the selected template does not support. Verify rejects the request because the template and channel combination is invalid.

• You selected a channel that is not available for the template you are trying to use.
• The template was created for a different delivery method, such as SMS or voice, and you sent the request with another channel.
• Your application passed an invalid channel value for the selected Verify template.
• The template configuration does not include support for the destination channel in your request.

• Check the template configuration and confirm which delivery channels it supports.
• Update your request so the channel value matches a supported channel for that template.
• If you need to send the verification over a different channel, use a template that supports that channel.
• Review your application logic to make sure it does not reuse a template across unsupported channels.
• If you manage templates dynamically, validate the selected template and channel combination before you send the Verify request.
