Automated Multi-Platform Image Posting for Social Media
detail.loadingPreview
This n8n workflow automates the process of fetching multiple images and simultaneously posting them to different social media platforms like Instagram and TikTok via a custom API. It streamlines content distribution, saving significant time and effort for social media managers and marketers.
About This Workflow
This powerful n8n workflow is designed for efficient social media management, enabling users to automatically retrieve and upload multiple images to specified platforms like Instagram and TikTok. By leveraging HTTP requests to fetch images from any URL and a custom external API (api.upload-post.com) for posting, it dramatically simplifies multi-platform content distribution. The workflow intelligently renames and merges binary image data to ensure a smooth multipart/form-form upload, making it a robust solution for anyone looking to automate their visual content strategy across various social channels. Stop manually uploading and start automating!
Key Features
- Automated Image Retrieval: Automatically fetches multiple images from specified URLs, preparing them for immediate social media posting.
- Multi-Platform Publishing: Simultaneously uploads images to multiple social media platforms, with pre-configuration for Instagram and TikTok.
- Custom API Integration: Seamlessly integrates with external posting APIs (
api.upload-post.com) using robustmultipart/form-datarequests. - Dynamic Image Handling: Intelligently renames and merges binary image data across multiple inputs into a single output, optimizing for API requirements.
- Secure API Authentication: Includes API key authorization for secure communication with your chosen posting service.
How To Use
- Trigger the Workflow: Manually activate the workflow by clicking the 'Test workflow' node. For production use, consider replacing it with a scheduled trigger (e.g., 'Cron' node) or a webhook.
- Configure Image Sources: Update the URLs in the "Get Image 1" and "Get Image 2" HTTP Request nodes to your desired image sources. You can add more 'Get Image' nodes if you need to upload more images simultaneously.
- Adjust Image Renaming (Optional): If you add more image sources, you must duplicate the 'Change name to photoX' code nodes for each new image. Ensure you modify the
indexin the code (e.g.,photo3,photo4) and connect these new nodes to the "Merge" node. - Set API Credentials: In the "POST TO INSTAGRAM1" and "POST TO TIKTOK" HTTP Request nodes, update the
Authorizationheader parametervaluewith your actual API key forapi.upload-post.com(or your chosen API). - Customize Post Details: Modify the
titleanduserbody parameters in both "POST TO INSTAGRAM1" and "POST TO TIKTOK" nodes to match your content and user profile. - Add/Remove Platforms: To add more social platforms, duplicate an existing 'POST TO' node, change the
platform[]value, and connect it to the "Send as 1 merged file" node. To remove a platform, simply delete the unwanted POST node.
