63027: Template does not exist for a language and locale

This error occurs when you send a channel message with a template language or locale that is not available for the template you referenced, or when you send the template with parameters that do not match the content template sending flow. Create or select a template in the correct language, then send it with ContentSid and, if needed, ContentVariables.

• The template you are trying to send was not created for the language or locale in your request.
• The template exists, but the template language does not match the one your application expects.
• You sent the template with the wrong API parameters instead of the content template parameters used by the Messaging API.

• Open the template in Console or fetch it with the Content API and confirm the template language before you send it.
• If you need a different language, create a template for that language. After a template is submitted for WhatsApp approval, you cannot change its language.
• Send the message with ContentSid and, if your template uses placeholders, ContentVariables.
• Do not include Body or MediaUrl when you send a content template with ContentSid.

• Send templates created with the Content Template Builder
• Create templates with the Content Template Builder in Console
• Content API public endpoints
