This n8n workflow streamlines the automated publishing of various media types, including images, videos, stories, reels, and carousels, directly to Instagram and Facebook. The process begins with a manual trigger, allowing users to configure post parameters such as media URLs, captions, and cover images. Depending on the post type, the workflow routes the content through specific handlers for images, stories, reels, or carousels, utilizing HTTP requests and Facebook Graph API nodes for posting media. It incorporates a robust status-checking and retry mechanism to ensure media processing is complete before final publication. For posting, it intelligently chooses between HTTP API and Facebook SDK based on the post type, facilitating versatile and reliable social media automation. This workflow is ideal for social media managers or marketers aiming to schedule and publish diverse content automatically across platforms with minimal manual intervention.
