SummaInstall

Overview

The node named "Summa" is designed to interact with the Summa API, specifically versioned as indicated in its description. It supports multiple resources and operations related to telecommunications data management. For the HLR Subscription resource with the Get Camel Info operation, the node retrieves CAMEL (Customized Applications for Mobile network Enhanced Logic) information associated with a given IMSI (International Mobile Subscriber Identity). This operation is useful in scenarios where telecom operators or service providers need to query subscriber-specific CAMEL service details for billing, routing, or service customization purposes.

Practical examples include:

• Fetching CAMEL service profiles for a subscriber identified by their IMSI.
• Integrating subscriber CAMEL info retrieval into automated workflows for telecom customer support or provisioning systems.

Properties

Output

The node outputs JSON data containing the CAMEL information related to the specified IMSI. The exact structure depends on the Summa API response but typically includes details about the subscriber's CAMEL service settings, such as service keys, triggers, and parameters relevant to customized call handling and charging.

If the node supports binary data output, it would represent any binary attachments or encoded data returned by the API, but this is not explicitly indicated in the provided code snippet.

Dependencies

• Requires an active connection to the Summa API via an API key credential (referred generically as an API authentication token).
• The node uses internal helper classes for HTTP requests, state management, and operation resolution/execution.
• No additional external services are explicitly required beyond the Summa API endpoint.

Troubleshooting

• Common issues:

  • Invalid or missing IMSI parameter will cause the operation to fail.
  • Authentication errors if the API key credential is invalid or expired.
  • Network connectivity problems when reaching the Summa API endpoint.
  • Unexpected API responses or changes in the Summa API schema might cause parsing errors.

• Error messages:

  • Authentication failures typically indicate issues with the provided API key; verify and update credentials.
  • Parameter validation errors suggest missing or malformed IMSI input; ensure the IMSI is correctly formatted.
  • HTTP request failures may require checking network access or API availability.
