n8n Workflow: Create Evergreen Content with GitHub Dynamic Images & URL Redirects

This n8n workflow automates the process of generating dynamic images and URL redirects for evergreen content, leveraging GitHub for storage and version control. It's designed to streamline the creation and management of visual assets and short URLs, making your content more engaging and trackable.

What it does

This workflow simplifies the following tasks:

1. Triggers: The workflow can be initiated in several ways:
   • Manually: By clicking 'Execute workflow' in the n8n editor.
   • On Schedule: At predefined intervals (e.g., daily, weekly).
   • On Form Submission: When data is submitted through an n8n form.
2. Image Editing: Processes and manipulates images using the Edit Image node. This could involve blurring, cropping, resizing, adding borders, compositing, drawing, or adding text to images.
3. GitHub Interaction: Interacts with GitHub, likely to store the generated images or content metadata. This allows for version control and easy access to your assets.
4. HTTP Requests: Makes HTTP requests, which could be used for various purposes such as:
   • Interacting with external APIs for data enrichment.
   • Creating or updating URL redirects on a custom service.
   • Publishing content to other platforms.
5. Gmail Integration: Sends emails via Gmail, potentially for notifications, approvals (Human-in-the-Loop), or sharing the generated content/redirects.
6. Sticky Notes: Includes a Sticky Note for documentation or internal comments within the workflow itself, helping to explain specific parts of the logic.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running n8n instance to import and execute the workflow.
• GitHub Account: With appropriate repository access for the GitHub node.
• Gmail Account: Configured with credentials for the Gmail node.
• External API/Service (Optional): If the HTTP Request node is used to interact with a specific service (e.g., a URL shortener API, an image hosting service), you will need an account and API key for that service.

Setup/Usage

1. Import the workflow: Download the JSON provided and import it into your n8n instance.
2. Configure Credentials:
   • Set up your GitHub credentials (e.g., OAuth App, Access Token) in n8n.
   • Set up your Gmail credentials (e.g., OAuth2) in n8n.
3. Configure Nodes:
   • Edit Image: Adjust the image manipulation operations (e.g., resize, add text, composite) according to your needs.
   • GitHub: Specify the repository, file paths, and commit messages for where images or content should be stored.
   • HTTP Request: Configure the URL, method, headers, and body for any external API calls (e.g., to create URL redirects).
   • Gmail: Customize the recipient, subject, and body of the emails to be sent.
4. Set up Trigger:
   • If using Schedule Trigger, define the desired interval for execution.
   • If using n8n Form Trigger, customize the form fields and share the webhook URL.
5. Activate the Workflow: Once configured, activate the workflow to start automating your content creation and redirect management.
