Quick overview
Quick overview This workflow runs daily, reads a Google Sheets content calendar for the next row marked todo, sends the idea to Canvora to generate branded visuals, then posts the finished image links (or a failure/timeout alert) to a Slack channel. How it works Runs every day at 8am on a schedule. Reads rows from a Google Sheets spreadsheet and keeps only items where the status column equals todo. Takes the first eligible row and submits its idea (plus optional format, language, and brandId) to the Canvora Generations API. Waits 30 seconds and repeatedly polls Canvora for the generation status until it completes or a timeout threshold is reached. If the generation completes successfully (including partial success), sorts the returned outputs and posts a Slack message with ordered image links and a Canvora review URL. If the generation fails, is cancelled, or times out, posts a Slack alert with the status and a link to the Canvora dashboard. Setup Connect Google Sheets credentials and select the target spreadsheet and sheet in the Google Sheets read step. Create a Canvora account, generate an API key, and add an HTTP Header Auth credential that sends X-API-Key: for the Canvora requests. Connect Slack credentials and set the destination channel for the review and failure notifications (for example, #content). Ensure your Google Sheet has headers that match the workflow fields (idea, format, language, brandId, status) and mark rows you want processed with status=todo. Adjust the schedule time and the timeout/polling behavior if you want a different daily run time or maximum wait duration. Requirements A free Canvora account (API keys on all plans).
