Interact with mittwald mStudio API

Actions409

Overview

This node allows authenticating a user by providing an access token retrieval key along with the user ID. It interacts with an external API to verify the user's credentials and retrieve an access token, which can then be used for subsequent authenticated requests within a workflow.

Common scenarios include:

  • Automating login processes where a user’s access token needs to be programmatically retrieved.
  • Integrating with systems that require token-based authentication without manual intervention.
  • Validating user identity before performing further actions in a workflow.

Example: A workflow that first authenticates a user by their access token retrieval key and user ID, then uses the returned access token to fetch user-specific data from another API endpoint.

Properties

Name Meaning
Access Token Retrieval Key The key used to retrieve the access token for the user. This is a required string input.
User Id The unique identifier of the user to authenticate. This is a required string input.

Output

The node outputs JSON data containing the response from the authentication API call. This typically includes the access token and possibly additional metadata related to the authenticated user session.

If binary data were involved (not indicated here), it would represent files or media associated with the user or authentication process, but this node focuses on JSON responses.

Dependencies

  • Requires an API key credential for authenticating requests to the external mittwald mStudio API.
  • The node depends on the @devlikeapro/n8n-openapi-node package for handling OpenAPI-based request building.
  • Network connectivity to https://api.mittwald.de is necessary.

Troubleshooting

  • Invalid Credentials: If the access token retrieval key or user ID is incorrect, the API will likely return an authentication error. Verify the inputs are correct.
  • Network Issues: Failure to reach the API endpoint may cause timeouts or connection errors. Check network settings and API availability.
  • Missing Required Fields: Ensure both "Access Token Retrieval Key" and "User Id" are provided; otherwise, the node will not execute properly.
  • API Rate Limits: Excessive requests might lead to rate limiting; handle such errors by implementing retries or backoff strategies.
