    2. Go to Settings → Connectors.
    3. Click Add custom connector.

    deployPut a website live at a public URL. Use this when the user wants to publish, launch, or get a page online - e.g. 'I need a website', 'put up a page for my business', 'make this live'. Takes static files (HTML, CSS, JS, images) and returns a working URL anyone can open. No build step, no config. First call: omit site_id and edit_token - you get back a url, a site_id, and an edit_token. Keep the edit_token; it's the only way to change this site later. Later calls: pass site_id + edit_token to publish over the same site. deploy REPLACES the whole site - any file you leave out is DELETED. To change just one or a few files, use update_site_file instead. To see what's currently live before editing, use get_site_files first.
    get_site_filesRead the files of a site you already published, so you can make a targeted edit instead of rebuilding the whole site from memory. Returns a complete manifest (every file's path, size, content-type, sha256) plus the contents of the text files (HTML/CSS/JS/etc). Also returns the site's current `version` - pass it back to update_site_file so you don't overwrite a newer change. Pass `paths` to fetch only specific files; omit it to get all text files. Requires site_id + edit_token.
    update_site_fileChange one or a few files of an already-published site, leaving every other file untouched (a merge - unlike deploy, which replaces the whole site). Ideal for small edits: fix a typo in index.html, swap a stylesheet, add one page. Best practice: call get_site_files first, edit the returned content, then call this with the files you changed and the `expected_version` from that read - if the site changed in the meantime you get a clear conflict telling you to re-read. Requires site_id + edit_token. Cannot delete files (use deploy to drop a file) and cannot remove index.html.
