Literal AI

Use the Literal AI API

Actions41

Overview

This node integrates with the Literal AI API to manage user data and other resources. Specifically, for the "User" resource with the "Get One" operation, it retrieves detailed information about a single user by their unique user ID. This is useful in scenarios where you need to fetch user profiles or metadata from the Literal AI platform, such as verifying user details before processing or displaying personalized content.

Practical example: You have a workflow that processes user interactions and needs to enrich the data with user profile information stored in Literal AI. Using this node, you can fetch the user’s full details by providing their user ID.

Properties

Name Meaning
User ID The unique identifier of the target user whose details you want to retrieve. It is a required string input.

Output

The node outputs a JSON object under the json field containing the user data returned by the Literal AI API. This includes all available user details such as identifiers, metadata, and any other user-specific information managed by the API.

If the API returns binary data related to the user (not indicated here), it would be included accordingly, but for this operation, the output is purely JSON-based user information.

Example output structure:

{
  "content": {
    "id": "string",
    "identifier": "string",
    "metadata": { /* user metadata object */ },
    // ... other user fields as provided by the API
  }
}

Dependencies

  • Requires an active connection to the Literal AI API.
  • Needs an API key credential configured in n8n to authenticate requests.
  • The node uses the official Literal AI client library internally to communicate with the API.

Troubleshooting

  • Common issues:

    • Invalid or missing User ID: Ensure the User ID property is correctly set and corresponds to an existing user.
    • Authentication errors: Verify that the API key credential is valid and has sufficient permissions.
    • Network or API downtime: Check connectivity and Literal AI service status.

  • Error messages:

    • "User not found": The specified User ID does not exist. Confirm the ID is correct.
    • "Authentication failed": The API key is invalid or expired. Update credentials.
    • JSON parsing errors on metadata inputs (for other operations): Ensure JSON strings are well-formed.
