How to post to Bluesky from n8n

Post to Bluesky from n8n, step by step

About eight minutes, on the free plan. On Oct 27, 2026 n8n's list of built-in app nodes ran from Bitwarden and Box straight to Brandfetch: there is no Bluesky node to configure, which is why the steps start with PostWire.

1. Create a free PostWire account

   Open postwire.io/dashboard.html, type your email and press Create my free account. PostWire emails you a link to confirm the address; connecting accounts and publishing unlock once it is confirmed. No password and no card (free plan: 1 business, 10 posts a month, 5 AI drafts a day (about 20 a month), 2 networks per post, 3 scheduled posts at a time — every network connects free, no card).

2. Connect Bluesky with an app password

   In Bluesky, open Settings → Privacy and security → App passwords, add one and copy it: it is not your account password, and deleting it in Bluesky disconnects PostWire. In the dashboard open Accounts, press Connect on Bluesky and paste your full handle (name.bsky.social or your own domain) and the app password. PostWire signs in to Bluesky with them before it saves anything, so a wrong handle or password is refused right there.

3. Copy your API key

   In the dashboard, open API & MCP and press Copy key on the API key card. It is sent as Authorization: Bearer pw_live_… (the X-API-Key header also works). Keep it server-side.

4. Install the PostWire node

   In n8n: Settings → Community nodes → Install, enter n8n-nodes-postwire (version 0.4.3 on npm on Oct 27, 2026), then add a PostWire API credential with the key and press Test, which checks the key at once. Where community nodes cannot be installed, the HTTP Request node further down does the same job.

5. Configure Post → Publish

   Networks: Bluesky. Content: Smart Distribute: Write a Native Post per Network, with the Idea from the previous node (e.g. {{ $json.title }} — {{ $json.link }}): the Bluesky draft stays within 300 characters, conversational, with one or two specific hashtags at most. To send your own words, set Content to Same Text on Every Network. Media: None, or URL / Binary File for an image. For a thread, open Options: Thread lists the posts after the first, in order, and First Comment adds one reply under the last post, the place for a link; or turn on Split Long Text Into a Thread and PostWire cuts a long text into posts itself. Dry Run checks everything without publishing.

6. Or one HTTP Request node

   POST to the REST API with header Authorization: Bearer pw_live_…. per_platform.bluesky.thread takes the posts after the first (up to 9), or true to split the text at a paragraph, then a sentence, then a word and never inside a link. media takes up to 4 images, each with its own alt:

   POST https://postwire.io/api/post
   Authorization: Bearer pw_live_…
   Content-Type: application/json
   
   {
     "platforms": ["bluesky"],
     "per_platform": { "bluesky": {
       "text": "{{ $json.hook }}",
       "thread": true,
       "first_comment": "Full post: {{ $json.link }}"
     } },
     "media": [
       { "url": "{{ $json.image }}", "type": "image", "alt": "{{ $json.image_alt }}" }
     ],
     "idempotency_key": "{{ $json.guid }}"
   }

7. Read the result, or schedule it

   The result carries the post's link (https://bsky.app/profile/…/post/…) and, for a thread, every post's id. If Bluesky refuses a later post of a thread, the earlier ones stay up and the result says which went out. To publish later, use Post → Schedule with When: At a Specific Time or In the Next Free Queue Slot (or POST /api/schedule with run_at).

With an RSS trigger, put the item's guid in Options → Idempotency Key (or idempotency_key): PostWire refuses a second post with the same key for 24 hours, so a re-run never posts the same article twice. A whole workflow, from the trigger to the post, is laid out in n8n social media automation.
