"content": "## AI Writes the Post, Canvora Designs It (Weekly Content on Autopilot)\n\n### How it works\n\nThis workflow runs every Monday morning to generate a weekly social post concept with AI, then sends it to Canvora to create branded designs. It polls Canvora until the generation completes, handles timeout or failure cases, and posts either a review-ready Slack message or a failure alert.\n\n### Setup steps\n\n- Configure the schedule trigger with the desired timezone and weekly run time.\n- Add OpenAI credentials in the OpenAI Write Post Concept node (or swap in Anthropic/Gemini \u2014 any text model works).\n- Create a free Canvora account at [canvora.ai](https://canvora.ai) \u2014 free credits included, no card required \u2014 and get an API key from canvora.ai \u2192 Integrations \u2192 API Keys (available on all plans).\n- In both Canvora HTTP Request nodes, use one shared Header Auth credential: name `X-API-Key`, value your `vd_...` key.\n- Set the campaign values in Set Campaign Parameters: topic, comma-separated formats, optional language, optional brand kit ID.\n- Connect Slack credentials and set the target channel for review messages and failure alerts.\n\n### Customization\n\n- Formats: 100+ available (carousels, quote_card, stat_card, blog_header, \u2026) \u2014 list them with GET https://api.canvora.ai/api/formats. Cost: 10 credits per visual, 15 per carousel slide.\n- Language: set e.g. `es` to run the whole pipeline in Spanish \u2014 Canvora generates natively in 150+ languages.\n- Brand kits: pass a brandId (GET /api/brands) so every visual uses your colors, fonts, and logo.\n- Adjust the polling interval, timeout logic, and Slack wording to fit your cadence."
