"content": "## Blog RSS \u2192 Branded Social Visuals (Canvora Autopilot)\n\n### How it works\n\nThis workflow watches an RSS feed for new blog posts and uses the Canvora API to generate branded social visuals from each post. It waits and polls Canvora until the generation is complete, then routes successful outputs to Slack for review or sends a failure notification if the job fails or times out.\n\n### Setup steps\n\n- Create a free Canvora account at [canvora.ai](https://canvora.ai) \u2014 free credits included, no card required.\n- Get an API key from canvora.ai \u2192 Integrations \u2192 API Keys (available on all plans).\n- In the two HTTP Request nodes, create one Header Auth credential: name `X-API-Key`, value your `vd_...` key.\n- Configure the RSS trigger with the blog feed URL to monitor.\n- Set the desired generation options in the Set Branding Configurations node: formats, carousel format and slide count, language, and brand kit ID.\n- Connect Slack credentials and choose the channels for review messages and failure alerts.\n\n### Customization\n\n- Formats: 100+ available (blog_header, quote_card, stat_card, ad_square, \u2026) \u2014 list them with GET https://api.canvora.ai/api/formats.\n- Language: leave empty to auto-detect from the article \u2014 Canvora generates natively in 150+ languages.\n- Brand kits: pass a brandId (from GET /api/brands) so every visual uses your colors, fonts, and logo.\n- Cost: default 2 visuals = 20 Canvora credits per run; a 5-slide carousel adds 75.\n- To publish automatically instead of reviewing, replace the Slack node with LinkedIn/Buffer nodes \u2014 each output has a public fileUrl you can attach directly.\n- Adjust the wait interval, timeout logic, and Slack message formatting to match the publishing process."
