Expiration must be provided for LTO templates created where has_expiration is true

Include the message object in the curl above only if the template has media. Refer image, video and document template docs to get the corresponding message payloads.

Omit the postbackTexts parameter in the curl above if the template doesn’t have quick reply buttons, or if it has but there’s no need for postback text support.
