Create Business Post

Publishes an UPDATE post (local post) to the Business Profile — visible on Maps/Search. summary = post text. Optional call-to-action: cta_type (LEARN_MORE|BOOK|ORDER|SHOP|SIGN_UP|CALL) + cta_url; CALL takes no url (Google dials the business phone number), every other type requires one. The button is read back from Google's reply and returned as cta_type. image_url attaches a PHOTO to the post itself (not the gallery): it must be a publicly reachable direct image link (Google downloads it server-side), JPG or PNG, at least 250px on the short edge and at least 10 KB. Without a public link, upload_image provides one: source_url re-publishes a photo that already lives on the web (the site, WordPress media, Drive) with no work for the user, or no arguments returns a drop link for up to 10 photos at once. language = post language code (tr|en|…); empty tags the post with the business location's OWN language, read from the profile (en if the profile declares none). SAFETY: confirm=false → preview, confirm=true → publish. location = a gbp_list_locations value or a business name/domain (auto-matched).
