SummaInstall

Overview

This node integrates with the Summa API to perform various operations related to telecommunications subscriptions and services. Specifically, the "Get All Supplementary Services" operation under the "SS Subscription" resource retrieves all supplementary services associated with a given IMSI (International Mobile Subscriber Identity). This is useful for telecom operators or service providers who need to query and manage subscriber supplementary services such as call forwarding, call barring, or other value-added services linked to a mobile subscriber.

Practical examples include:

• Fetching all active supplementary services for a subscriber to display in a customer portal.
• Auditing or verifying subscriber service configurations during troubleshooting.
• Automating service management workflows based on subscriber data.

Properties

Output

The node outputs JSON data representing the list of all supplementary services associated with the specified IMSI. The structure typically includes details about each supplementary service, such as service type, status, activation date, and any relevant parameters defined by the Summa API.

If the node supports binary data output (not indicated here), it would represent supplementary service data in a binary format, but this is not evident from the provided code.

Dependencies

• Requires an API key credential for authenticating with the Summa API.
• Depends on the Summa API endpoint accessible via HTTP requests.
• Uses internal helper classes for state management and operation execution.
• Requires proper configuration of the "summaApi" credential within n8n to enable authenticated requests.

Troubleshooting

• Missing or invalid IMSI: Since IMSI is required, ensure it is provided and correctly formatted; otherwise, the node will fail to retrieve data.
• Authentication errors: If the API key credential is missing, expired, or incorrect, authentication will fail. Verify the credential setup in n8n.
• API connectivity issues: Network problems or incorrect API endpoint configuration can cause request failures. Check network access and API availability.
• Unexpected API responses: If the Summa API changes or returns errors, the node may throw exceptions. Review API documentation and update credentials or parameters accordingly.
