Who is this workflow for?
This workflow is the baseline workflow for anyone who needs to automate the process of posting 1-4 images to Bluesky using the Bluesky API. It is ideal for anyone looking to streamline their social media posting process, saving time and ensuring consistent content delivery.
Use Case / Problem Solved
Manually posting images and captions on Instagram can be time-consuming, especially for businesses and content creators managing multiple accounts. This workflow automates the process from image preparation to publishing, reducing manual effort and increasing efficiency.
What this workflow does
- Trigger Initialization: The workflow starts with a manual trigger that can be adapted to other triggers (e.g., HTTP webhook or schedule).
- Set Parameters: The workflow includes a node that sets essential parameters, such as the Bluesky account ID, image URLs, and caption.
- Prepare Bluesky Session: A node creates the authenticated session data used by the upload and post operations later in the workflow.
- Publish Media: Nodes retrieve image files from the specified URLS and uploads them as blobs to Bluesky, a necessary pre-requisite for a Bluesky post to have images attached.
- Post text caption + images: A node does the final call to the Bluesky API, including the text caption and relevant image references.
Setup
- Sign-in to Bluesky and create an App Password
- Add your username and App Password to the Define Credentials node.
- Set the caption (text content) of your post in the Set Caption node.
- Set 1-4 image URLs in the Set Images node
- Adapt the initial trigger as needed to fit your workflow's requirements (e.g., schedule, webhook).
- Adapt the caption and images nodes to accept dynamic parameters.
Limitations
This workflow assumes a minimum of 1 image URL to function. If you want a text-only post, remove the whole embed section from the JSON in last Post to Bluesky node, as well as relevant image attachment nodes.
The 300-character limit in Bluesky includes the caption + hashtags + image alt text. Going over 300 will return a Record/description must not be longer than 300 graphemes error.
