Build Your First API Endpoint with n8n: A Simple Webhook Example
detail.loadingPreview
Learn to quickly create a functional API endpoint using n8n's intuitive Webhook and Respond to Webhook nodes. This workflow demonstrates how to receive data, process it, and return a custom response, perfect for integrations and simple API creation.
About This Workflow
This n8n workflow showcases the power and simplicity of building your own API endpoint. By utilizing the Webhook node, you can expose a unique URL that listens for incoming requests. The workflow then processes the data from the request, in this example, creating a Google search URL based on provided first and last names. Finally, the Respond to Webhook node sends back a dynamic response, confirming the action taken and providing the generated URL. This is an excellent starting point for anyone looking to integrate external services or build quick, custom API functionalities without writing extensive code.
Key Features
- Instant API Endpoint Creation: Set up a webhook to receive incoming HTTP requests in minutes.
- Dynamic Data Processing: Transform and manipulate incoming data with n8n's powerful expression engine.
- Customizable Responses: Return tailored text or JSON responses to your API callers.
- No-Code Integration: Build functional APIs without writing traditional backend code.
How To Use
- Execute the Workflow: Run this n8n workflow to activate the
Webhooknode and make it listen for incoming requests. - Obtain the Test URL: Copy the unique URL provided by the
Webhooknode. - Send a Test Request: Paste the test URL into a new browser tab. Append query parameters to simulate data, for example:
?first_name=bob&last_name=dylan. - View the Response: The browser will display a response similar to:
The URL of the Google search query for the term "bob dylan" is: https://www.google.com/search?q=bob+dylan.
