Canva Autofill API alternative: n8n and templated.io social graphics
Send a blog URL to a Telegram bot. n8n scrapes the title, description and featured image, fills a design template (imported from Canva) through templated.io's render API, and has GPT-4 write captions. It then publishes the graphic to Facebook, Instagram and X.
Setup steps
- Import a public Canva template into templated.io and mark editable layers with '-change'
- Telegram trigger in n8n; check the message is a valid URL
- Fetch the post and extract title, description and image with CSS selectors
- Map the data to the template layers and call templated.io's render API
- Have GPT-4 write captions, then publish (add an approval step first)

Help me set up this automation using n8n + templated.io + GPT-4 + Telegram: "Canva Autofill API alternative: n8n and templated.io social graphics". Goal: replace Canva Autofill API (Enterprise). How it should work: - Trigger: You send a blog URL to Telegram - Then: n8n scrapes the post - Then: templated.io renders the graphic - Then: GPT-4 writes captions - Result: Graphic posted to Facebook, Instagram and X Setup steps (summarized from the original source): 1. Import a public Canva template into templated.io and mark editable layers with '-change' 2. Telegram trigger in n8n; check the message is a valid URL 3. Fetch the post and extract title, description and image with CSS selectors 4. Map the data to the template layers and call templated.io's render API 5. Have GPT-4 write captions, then publish (add an approval step first) Guide me one step at a time. Ask me for anything you need (accounts, sheet or channel names) before you start. Safety rules: - Build and test with sample data first, and show me a sample result before anything goes live. - Keep anything that goes to other people (emails, posts, replies, record updates) as drafts for my review until I say otherwise. - Never send, post, buy, pay, delete or change records without my approval. - Tell me about any cost (paid plans, API usage) before I'd incur it, and help me set a spending limit. - Keep API keys and passwords out of shared docs and chats. - Privacy: Blog content goes to templated.io and OpenAI; posts go out through a social publishing API.
