For example, if the template defines a phone number button first (which equates to index 0) and a URL button that supports a single variable second (which equates to index 1), if you attempt to send the template with the URL button index set to 0 , the API would return an error ("Parameter value for URL was expected but was not found") because it's expecting a button object with an index of 1 to be present in the post body payload.
