n8n Form Triggered Workflow

This n8n workflow automates a process initiated by a form submission, potentially involving API interactions, conditional logic, and looping through data. It's designed to handle a single item at a time, performing specific actions based on certain conditions.

What it does

This workflow is triggered by an n8n form submission and processes the submitted data through a series of steps:

1. Listens for Form Submissions: The workflow starts when an n8n form is submitted, capturing the data provided in the form.
2. Makes an HTTP Request: It then sends an HTTP request, likely to an external API, using the data from the form submission.
3. Splits Out Data: The response from the HTTP request is processed, and specific items or arrays within the data are split out for individual handling.
4. Loops Over Items: For each item split out, the workflow enters a loop to process them sequentially.
5. Applies Conditional Logic: Inside the loop, an "If" node evaluates a condition based on the current item's data.
6. Executes Custom Code (Conditional): If the condition in the "If" node is met (TRUE branch), a "Code" node is executed, allowing for custom JavaScript logic to be applied to the data.
7. Waits (Conditional): After the "Code" node, the workflow pauses for a specified duration using a "Wait" node. This suggests a rate-limiting or timing requirement for subsequent actions.

Prerequisites/Requirements

• n8n Instance: A running n8n instance to host and execute the workflow.
• n8n Form: An n8n form configured to trigger this workflow.
• External API: Access to an external API that the "HTTP Request" node interacts with. You will need the API endpoint, method, and any required authentication or body parameters.
• JavaScript Knowledge: For customizing the "Code" node, basic JavaScript knowledge is required.

Setup/Usage

1. Import the Workflow: Import the provided JSON into your n8n instance.
2. Configure the n8n Form Trigger:
   • Open the "On form submission" node.
   • Configure the form fields as needed for your use case.
   • Share the form URL to collect submissions.
3. Configure the HTTP Request Node:
   • Open the "HTTP Request" node.
   • Set the URL, Method (e.g., GET, POST), and any Headers or Body parameters required by your external API. You will likely need to reference data from the "On form submission" node using expressions (e.g., {{ $json.form_field_name }}).
   • Configure any necessary Credentials for API authentication.
4. Configure the Split Out Node:
   • Adjust the "Split Out" node to correctly target the array or items you wish to process iteratively from the "HTTP Request" node's output.
5. Configure the If Node:
   • Open the "If" node.
   • Define the Conditions that will determine which branch of the workflow is executed. This condition will likely use data from the items being looped over.
6. Configure the Code Node (Optional):
   • If you need custom logic, open the "Code" node (connected to the TRUE branch of the "If" node).
   • Write your JavaScript code to transform or manipulate the data as required.
7. Configure the Wait Node (Optional):
   • Open the "Wait" node.
   • Set the desired Wait Time (e.g., seconds, minutes) to introduce a delay in the workflow.
8. Activate the Workflow: Once configured, activate the workflow to start listening for form submissions.
