This n8n workflow automates the process of posting images and a caption to Bluesky, a decentralized social network. It streamlines image upload and post creation, making it ideal for users who want to efficiently share multiple images with a caption. The workflow is triggered manually for testing or scheduling.
The process begins with a manual trigger, allowing user-initiated execution. Credentials for Bluesky are defined, and a session is created via an HTTP request to Bluesky’s API. The workflow then specifies a set of image URLs, which are downloaded individually. Each image is uploaded as a blob to Bluesky’s server through separate requests, capturing the necessary identifiers for embedding.
Using a code node, the workflow compiles the uploaded images into the required format for embedding in a post. A caption is set in a dedicated node, and all data is aggregated for the final post. The post, including the caption and embedded images, is created on Bluesky via an HTTP request, authenticated with the session token.
This setup is practical for content creators or social media managers aiming to automate multi-image posts on Bluesky, saving time and ensuring consistent formatting.
