Any dude could disclose how to do this?
What I want is, to use Facebook Graph API to post on my own page. The post should have the call_to_action button, which is linked to https://m.me/mypage
There's not much on call_to_action topic on graph api documentation. Scraphing through Google shows no related results/experiences. The ads-doc is restricted to ads-posts and not complete!
The following cta-types are not working: MESSAGE_PAGE, OPEN_MESSENGER_EX, OPEN_LINK and GET_OFFER... They all do not accept link to https://m.me. But external link likes: http://stackoverflow.com will works.
Following error shows:
(#100) Call-to-action is only supported for external links and some types of Facebook links.
Any help are appreciated :) Thank guys
