n8n Form Trigger with Google Docs and HTTP Request

This n8n workflow provides a robust solution for processing form submissions, conditionally storing data in Google Docs, and making an HTTP request. It acts as a flexible backend for forms, allowing you to react differently based on the submitted data.

What it does

This workflow automates the following steps:

1. Listens for Form Submissions: It is triggered by an n8n form submission, capturing the data provided by the user.
2. Conditional Logic: It evaluates the submitted data using an "If" node. This allows for branching logic based on specific conditions in the form data.
3. Stores Data in Google Docs (Conditional): If the condition in the "If" node evaluates to true, the workflow proceeds to write the submitted data into a specified Google Doc.
4. Makes an HTTP Request (Conditional): If the condition in the "If" node evaluates to false, the workflow instead makes an HTTP request. This could be used for integrating with other APIs, sending notifications, or triggering external systems.
5. Responds to Webhook: After processing, the workflow sends a response back to the original webhook trigger, indicating completion.
6. Code Execution: Includes a "Code" node, which suggests custom JavaScript logic can be executed at a specific point in the workflow. This node is currently not connected, implying it might be a placeholder for future enhancements or specific data manipulation.
7. Sticky Note: A sticky note is present, likely for documentation or temporary notes within the workflow itself.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running n8n instance to import and execute the workflow.
• Google Account: A Google account with access to Google Docs for the "Google Docs" node. You will need to set up Google OAuth credentials in n8n.
• HTTP Endpoint: If the "If" condition evaluates to false, an external API or service endpoint to which the "HTTP Request" node will send data.
• n8n Form: An n8n form configured to trigger this workflow.

Setup/Usage

1. Import the Workflow: Download the provided JSON and import it into your n8n instance.
2. Configure Credentials:
   • Google Docs: Set up your Google OAuth2 credentials in n8n and select them in the "Google Docs" node. Specify the Google Doc ID and the data you wish to write.
3. Configure the n8n Form Trigger:
   • Access the "n8n Form Trigger" node.
   • Define the form fields you expect to receive.
   • Copy the generated webhook URL to use in your form.
4. Configure the "If" Node:
   • Open the "If" node and define your desired conditions based on the data received from the "n8n Form Trigger".
   • For example, you might check if a specific field contains a certain value.
5. Configure the "HTTP Request" Node:
   • If the "If" node's false branch is used, configure the "HTTP Request" node with the target URL, method (GET, POST, etc.), headers, and body as required by your external API.
6. Activate the Workflow: Once configured, activate the workflow.
7. Submit the Form: Submit data to the n8n form to trigger the workflow and observe the execution path based on your "If" node conditions.
8. Customize Code Node (Optional): If you need custom data processing, connect the "Code" node and add your JavaScript logic.
