n8n Workflow: Generate TikTok Ad Copy with OpenAI and Slack Approval

This n8n workflow automates the generation of TikTok ad copy using OpenAI and facilitates a human-in-the-loop approval process via Slack. It provides a structured way to request new ad copy, get AI-generated suggestions, and then approve or reject them, ensuring quality control before final use.

What it does

This workflow streamlines the ad copy creation and approval process through the following steps:

1. Triggers on Form Submission: The workflow starts when a new request for ad copy is submitted via an n8n form.
2. Generates Ad Copy with OpenAI: It sends the form data to OpenAI to generate creative TikTok ad copy.
3. Formats Data: The generated ad copy and relevant details are formatted for clarity.
4. Sends for Slack Approval: The formatted ad copy is then sent to a designated Slack channel for review and approval.
5. Conditional Routing: Based on the approval status in Slack, the workflow can branch to subsequent actions (e.g., if approved, update a database; if rejected, notify the requester, etc. - Note: The provided JSON only shows the Slack approval step and an "If" node, further actions for approved/rejected states would need to be configured.).

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running n8n instance.
• OpenAI API Key: An API key for OpenAI to access its language model capabilities.
• Slack Account: A Slack workspace and a Slack App configured with appropriate permissions to send messages.
• n8n Form: An n8n form configured to trigger this workflow with the necessary input fields for ad copy generation requests.

Setup/Usage

1. Import the Workflow:
   • Copy the provided JSON code.
   • In your n8n instance, click "Workflows" in the left sidebar.
   • Click "New" or the "+" icon.
   • Click "Import from JSON" and paste the copied JSON.
   • Click "Import".
2. Configure Credentials:
   • OpenAI: Set up your OpenAI credential. You will need your OpenAI API Key.
   • Slack: Set up your Slack credential. This typically involves creating a Slack App and obtaining a Bot User OAuth Token.
3. Configure Nodes:
   • On form submission (Form Trigger): Configure the form fields that will be used to request ad copy (e.g., product name, target audience, key message, desired tone).
   • OpenAI: Configure the OpenAI node to use the appropriate model and prompt for generating TikTok ad copy based on the input from the form.
   • Edit Fields (Set): Review and adjust how the data is transformed and prepared for the Slack message.
   • Slack: Configure the Slack node to send the generated ad copy to your desired Slack channel. Ensure the message format includes clear options for approval/rejection (e.g., using Slack buttons or a specific message format that the "If" node can interpret).
   • If: Configure the "If" node to check the response from Slack (e.g., if an "Approved" button was clicked, or a specific keyword was used).
4. Activate the Workflow: Once all nodes are configured and credentials are set, activate the workflow to start listening for form submissions.

This workflow provides a robust foundation for integrating AI-powered content generation with a human review process, ensuring that your TikTok ad copy is both creative and aligned with your brand's standards.
