n8n Workflow: Basic Webhook Trigger with Conditional Logic

This n8n workflow demonstrates a fundamental setup for receiving data via a webhook, applying conditional logic, and then performing a subsequent action (or doing nothing) based on that logic. It's a versatile template for starting any workflow that needs to react to external events and make decisions.

What it does

This workflow simplifies the process of:

1. Receiving External Data: It listens for incoming HTTP requests (webhooks).
2. Applying Conditional Logic: It evaluates the received data against a defined condition.
3. Branching Workflow Execution: Based on the condition's outcome, it directs the workflow to either a "true" path (where an action like updating HubSpot would typically occur) or a "false" path (where no action is currently defined).

Key Steps

1. Webhook Trigger: The workflow starts by exposing a unique URL that can receive HTTP POST requests. Any data sent to this URL will initiate the workflow.
2. Conditional Check (If Node): The data received from the webhook is then passed to an "If" node. This node is configured to evaluate a specific condition on the incoming data.
3. HubSpot Action (True Path): If the condition in the "If" node evaluates to true, the workflow proceeds to a "HubSpot" node. Note: The specific operation for the HubSpot node is not defined in the provided JSON, but this is where you would configure actions like creating or updating a company, contact, or deal in HubSpot.
4. No Operation (False Path): If the condition in the "If" node evaluates to false, the workflow proceeds to a "No Operation, do nothing" node. This path essentially ends the workflow for items that do not meet the specified condition.
5. Code Node (Unconnected): There is an unconnected "Code" node present in the workflow. This node is typically used for custom JavaScript logic, data transformation, or more complex conditional checks that cannot be handled by standard nodes. It is currently inactive.
6. Sticky Note (Unconnected): A "Sticky Note" is included, likely for documentation or reminders within the workflow canvas. It does not affect workflow execution.

Prerequisites/Requirements

• n8n Instance: An active n8n instance (cloud or self-hosted) to import and run the workflow.
• Webhook Source: An external application or service capable of sending HTTP POST requests to the n8n webhook URL.
• HubSpot Account: If you intend to use the HubSpot integration, you will need a HubSpot account and appropriate API credentials configured in n8n.

Setup/Usage

1. Import the Workflow:
   • Copy the provided JSON content.
   • In your n8n instance, click on "Workflows" in the left sidebar.
   • Click "New" or "Add Workflow".
   • Click the three-dot menu (...) in the top right and select "Import from JSON".
   • Paste the JSON content and click "Import".
2. Configure the Webhook:
   • Open the "Webhook" node.
   • The "Webhook URL" will be automatically generated. Copy this URL.
   • Configure your external application or service to send POST requests to this URL.
3. Configure the If Node:
   • Open the "If" node.
   • Define the condition(s) that the incoming webhook data should meet. For example, you might check if a specific field in the JSON payload equals a certain value.
4. Configure HubSpot (if applicable):
   • Open the "HubSpot" node.
   • Select or create a HubSpot credential.
   • Configure the desired operation (e.g., "Create/Update Company", "Create Contact") and map the data from the incoming webhook to the relevant HubSpot fields.
5. Activate the Workflow:
   • Once configured, toggle the workflow to "Active" in the top right corner of the n8n editor.

Now, whenever your external service sends data to the webhook URL, the workflow will execute, evaluate the condition, and perform the HubSpot action if the condition is met.
