Note that the size limit with the lowest value between the WhatsApp size limit and the Clickatell API limit will apply. For example. the size limit for an image is 5MB (see table below) - WhatsApp will not accept an image above 5MB even though the Clickatell API can accept a larger media/template media message request.
WhatsApp (on inbound messages) can implement new supported content types or codes anytime – you'll need to handle this dynamically.
