Change a scheduled or draft post before it goes out, or edit a post that is already live on a channel that supports editing (list_platforms features: today Naver Blog, YouTube and some Facebook posts). Fields: content, mediaIds, accountIds, options, scheduledAt or draft. Fields you leave out keep their current value (on a Naver Blog post, see media below); options you pass replace the whole options object (on a post written directly on the channel they are merged per channel key instead). scheduledAt moves the send time (same rules as publish), null turns it into a draft, and draft: true does the same. A thread (chain) can be changed too while it is scheduled or a draft: content replaces the first item and keeps the later items; threadItems replaces the whole chain (one item collapses it to a single post); passing threadItems to a single post turns it into a chain. Pass id of the first item — later items return 409 thread_piece with rootId. Posts that already went out return post_not_editable on channels that cannot edit a live post. A post written directly on the channel (one a link or id resolved to, origin imported) can be edited on YouTube, on the text of Facebook text, link and photo posts, and on Naver Blog: uplika reads the post from the channel first, so fields you leave out keep the channel's current values. Elsewhere it returns post_not_editable with the reason (list_platforms feature update_imported). A Naver post written in Naver's editor is rewritten from its current source, which uplika reads from Naver's edit screen: text, bold, italic, underline, strikethrough and links are markdown; headings and quotes are markdown only when their text has no style at all; every other block (photos, videos, cards, tables, headings or quotes with a font, and whole text blocks that have colors, sizes or alignment anywhere, several paragraphs each) is one @keep(...) line. A line holding only an invisible U+200B character is blank space at the edge of a text block; leave it to keep the spacing. Send the edited source as content together with sourceVersion. Without it, or when the post changed on Naver since, this returns 409 naver_source_required with the current source and its sourceVersion (get_post also shows sourceVersion, but its content is only the source after uplika has read it once). Keep a @keep line to keep that block where it is, delete it to remove the block; text you write directly next to a @keep text block joins that block, and comes back inside its @keep line on the next read. An unknown id returns 422 naver_keep_unknown. This needs extension 0.7.8 or later (422 extension_outdated otherwise). A published Naver post is rewritten in place (same URL, same logNo) when you pass content, mediaIds or options. On a post that goes only to Naver Blog, the media: references in the new body are the post's media list: when you leave mediaIds out, media the new body does not place is removed from the post and the response note says how many. Pass mediaIds only for media to add at the end of the post without placing it in the body. If the body places more photos or videos than Naver takes (list_platforms), this returns 422 naver_media_over_limit with droppedIds and nothing changes. Naver Blog caps how many posts one ID publishes; when it does, this returns 429 naver_rate_limited with retryAfterSeconds. Do not call again before that, the draft is already in Naver. Naver Blog asks which form to publish with, every post: if options.naver_blog.form is missing this returns 400 naver_form_required with forms (id, name, when). The form is the house style to use when the person has no style of their own, so read the conversation first. If they dictated the structure or you laid it out yourself, pass options.naver_blog.layout: "as-is" and the markdown goes out unchanged. Otherwise show them the forms (naver_layout with forms: "all" lays every one out side by side) and call again with the one they pick. Do not pick for them. If the Naver editor shows a "missing image" error when you open an already-published post for editing, calling update_post on that post rewrites it in place and fixes it; the URL stays the same. A Naver draft (a target whose externalId starts with draft:, from options.naver_blog.draftOnly) is not on the blog: update_post publishes uplika's copy as a new post and, with extension 0.7.2 or later, removes the old draft from Naver's draft box. To publish the draft exactly as it is in Naver, call publish_naver_draft. Editing a post that is already live is asynchronous: pass wait: true to hold the response for the result (up to 75 seconds), or read it with get_post. If the account that published the post was disconnected, this returns 409 account_disconnected; reconnect the same account and the post id comes back.
