n8n Conditional Webhook Responder

This n8n workflow demonstrates a basic conditional logic setup for responding to incoming webhooks. It receives data via a webhook, applies a condition to that data, and then responds to the webhook based on whether the condition is met.

What it does

1. Listens for incoming data: The workflow starts by waiting for an HTTP POST request to its webhook URL.
2. Applies conditional logic: It then evaluates the data received by the webhook using an "If" node. This node can be configured to check for various conditions (e.g., specific values in the payload).
3. Responds to the webhook: Regardless of the condition, the workflow uses a "Respond to Webhook" node to send a response back to the caller.
4. Includes a Sticky Note: A sticky note is present for documentation or temporary notes within the workflow.
5. Includes a Code node: A "Code" node is present, allowing for custom JavaScript execution, though it is not connected in this particular workflow.

Prerequisites/Requirements

• An n8n instance (self-hosted or cloud).
• No external API keys or accounts are strictly required for this basic structure, but they would be needed if the "If" condition or the "Respond to Webhook" node were configured to interact with other services.

Setup/Usage

1. Import the workflow:
   • Copy the provided JSON code.
   • In your n8n instance, click "New" in the workflows list.
   • Click the "Import from JSON" button and paste the JSON.
   • Click "Import".
2. Configure the Webhook:
   • Click on the "Webhook" node.
   • The "Webhook URL" will be generated automatically. You can copy this URL to send test requests to it.
   • Ensure the "HTTP Method" is set to POST (or GET if you intend to send data via query parameters).
3. Configure the "If" node:
   • Click on the "If" node.
   • Define your desired conditions. For example, you might check {{ $json.someProperty === 'someValue' }}.
   • The workflow currently has no connections from the "If" node's TRUE/FALSE outputs, meaning the "Respond to Webhook" node will always execute regardless of the "If" condition's outcome in its current state. You would typically connect the TRUE/FALSE outputs to different subsequent actions.
4. Configure the "Respond to Webhook" node:
   • Click on the "Respond to Webhook" node.
   • You can customize the "Response Mode" (e.g., Last Node to send the output of the previous node, or Specify Output to send a custom JSON or text response).
   • Customize the "Response Body" as needed.
5. Activate the workflow:
   • Toggle the "Active" switch in the top right corner of the n8n editor to enable the workflow.
6. Test the workflow:
   • Send a POST request to the Webhook URL (e.g., using Postman, curl, or a simple HTML form).
   • Observe the execution in n8n to see how the "If" node evaluates the incoming data and how the "Respond to Webhook" node replies.
