🎬 Create weekly social visuals from OpenAI ideas with Canvora and Slack

⚡ 8 views · 🎬 Content Creation & Video

Description

Quick overview

This workflow runs every Monday and uses OpenAI to generate a social post concept, then sends it to the Canvora API to create on-brand visuals in selected formats and posts the finished image links to a Slack channel for review.

How it works

1. Runs every Monday at 9am on a scheduled trigger.
2. Sets campaign parameters like topic, desired output formats, optional language, and optional Canvora brand kit ID.
3. Uses OpenAI to write a single, specific social post concept based on the configured topic.
4. Sends the concept to Canvora to generate visuals in the requested formats (and applies language/brand settings when provided).
5. Polls Canvora for generation status until it completes or a timeout threshold is reached.
6. If generation succeeds, sorts the outputs and posts a Slack message with the file URLs and a Canvora review link; otherwise, it posts a failure/timeout notice to Slack.

Setup

1. Add an OpenAI API credential and select the model you want to use for generating the post concept.
2. Create a Canvora account, generate an API key, and configure an HTTP Header Auth credential named X-API-Key with your Canvora key for the Canvora HTTP requests.
3. Add a Slack credential and set the target channel (for example, #content) where the review or failure messages should be posted.
4. Update the campaign settings (topic, comma-separated formats, and optional language/brandId) and adjust the schedule time if needed.

Requirements

• • An OpenAI API key (or swap the node for Anthropic/Gemini — any text model works)
• A free Canvora account – canvora.ai, free credits included, no card required; API keys on all plans (Integrations → API Keys)
• A Slack workspace for the review channel

Customization

• Change the topic, formats (100+ available via the Canvora formats API), language (150+ generated natively), or brand kit in one Set node
• Swap Slack for LinkedIn/Buffer nodes to go fully automatic
