SummaInstall

Overview

This node, named "Summa," is designed to interact with the Summa API (version indicated in the node description). It supports multiple resources and operations related to telecommunications data management. Specifically, for the resource Send Protocol and operation Send Cancel Location To Current VLR, the node sends a cancel location request to the current Visitor Location Register (VLR) associated with a subscriber's ICC ID. This operation is typically used in mobile network management scenarios where it is necessary to update or clear subscriber location information in the network.

Practical examples include:

• Cancelling the location of a subscriber in the current VLR when they deregister or move to another network.
• Managing subscriber mobility and session state in telecom backend systems.
• Automating network operations that require signaling updates to the VLR.

Properties

Output

The node outputs JSON data representing the response from the Summa API after attempting to send the cancel location request. The exact structure depends on the API response but generally includes status information about the success or failure of the operation.

If the node supports binary data output, it would typically represent any raw protocol messages or logs returned by the API, but this is not explicitly shown in the provided code snippet.

Dependencies

• Requires an API key credential to authenticate with the Summa API.
• Depends on the @digital-boss/n8n-designpatterns package for resource-operation resolution and execution patterns.
• Uses internal helper classes for HTTP requests (HttpClient), state management (State), and operation methods (operationMethods).
• The node expects proper configuration of the Summa API credentials within n8n.

Troubleshooting

• Common issues:

  • Invalid or missing ICC ID input will cause the operation to fail.
  • Authentication errors if the API key credential is incorrect or expired.
  • Network connectivity problems when reaching the Summa API endpoint.
  • Unexpected API responses due to version mismatches or unsupported operations.

• Error messages:

  • Authentication failures usually indicate invalid credentials; verify and update the API key.
  • Validation errors on the ICC ID suggest checking the input format and ensuring it matches expected values.
  • Timeout or connection errors imply network issues or incorrect API endpoint configuration.

Resolving these typically involves verifying input parameters, ensuring valid credentials, and confirming network access to the Summa API.
