SummaInstall

Overview

This node, named "Summa," is designed to interact with the Summa API (version indicated dynamically). It supports multiple resources and operations related to telecommunications data management. Specifically, for the resource SS Subscription SOAP and operation Get Msisdn By Msisdn, the node retrieves information about a mobile subscriber identified by their MSISDN (Mobile Station International Subscriber Directory Number).

Typical use cases include:

• Querying subscriber details in telecom systems by providing an MSISDN.
• Integrating telecom backend services into workflows that require subscriber verification or data retrieval.
• Automating subscriber data lookups within larger automation pipelines.

For example, a user might input an MSISDN to fetch associated subscription details or validate the number's status via the Summa API.

Properties

Output

The node outputs JSON data containing the response from the Summa API corresponding to the queried MSISDN. The structure of this JSON depends on the API response but generally includes subscriber details linked to the provided MSISDN.

If the API returns binary data (not explicitly shown in the code), it would typically represent raw data such as documents or files related to the subscriber, but this node primarily handles JSON responses.

Dependencies

• Requires an API key credential for authenticating with the Summa API.
• Uses internal helper classes for HTTP requests (HttpClient), state management (State), and operation resolution/execution (ResOpResolver, ResOpExecutor).
• The node depends on the external Summa API service being available and reachable.
• The user must configure the node with valid credentials for the Summa API.

Troubleshooting

• Authentication errors: If the API key or credentials are invalid or missing, the node will fail to authenticate. Ensure the correct API key is configured.
• Invalid MSISDN input: Since the MSISDN property is required, leaving it empty or providing an incorrectly formatted number may cause the API call to fail or return no results.
• API connectivity issues: Network problems or incorrect endpoint configurations can lead to request failures.
• Unexpected API responses: Changes in the Summa API response format could cause parsing issues; verify API version compatibility.
