Interact with Petstore API

Actions17

Overview

This node allows you to retrieve information about a user by their username. It is useful in scenarios where you need to fetch user details from an external system or API based on the username, such as verifying user existence, retrieving profile data, or integrating user information into workflows.

For example, you might use this node to:

  • Get detailed information about a specific user before processing their data.
  • Validate if a username exists in the system.
  • Fetch user attributes for personalization or reporting purposes.

Properties

Name Meaning
Username The name of the user to fetch. For testing, you can use "user1". This is a required field.

Output

The node outputs JSON data containing the details of the user identified by the provided username. The structure typically includes user attributes such as ID, name, email, and other profile-related fields depending on the API's response schema.

If the node supports binary data output (not evident from the provided code), it would represent any files or media associated with the user, but no such indication is present here.

Dependencies

  • Requires access to an external API endpoint that provides user information by username.
  • Needs proper API authentication configured in n8n credentials (e.g., an API key or token).
  • The base URL and headers are set to interact with the Petstore API (https://petstore3.swagger.io/api/v3), which suggests this example is based on a Swagger Petstore API mock.

Troubleshooting

  • User Not Found: If the username does not exist, the node may return an error or empty result. Verify the username spelling and ensure the user exists in the target system.
  • Authentication Errors: Ensure that the API credentials are correctly configured and valid.
  • Network Issues: Check connectivity to the API endpoint.
  • Invalid Input: The username property is required; leaving it empty will cause the node to fail.
