Overview
This node, named "Summa," integrates with the Summa API to perform various operations related to telecommunications data management. Specifically, for the resource IMSI and operation Find IMSIs Of Sim, it retrieves IMSI (International Mobile Subscriber Identity) numbers associated with a given SIM card identified by its ICC ID.
Common scenarios where this node is beneficial include:
- Telecom operators or service providers needing to query IMSI details linked to a specific SIM card.
- Systems that manage subscriber information and require synchronization or validation of SIM-related identities.
- Automation workflows that involve SIM card inventory or lifecycle management.
For example, a workflow could use this node to input an ICC ID from a SIM card scanned during activation and retrieve all IMSIs tied to that SIM, enabling further processing or verification steps.
Properties
| Name | Meaning |
|---|---|
| Icc Id | The unique identifier of the SIM card (Integrated Circuit Card Identifier). This string is required to find IMSIs associated with the SIM. |
Output
The node outputs JSON data containing the IMSI information retrieved from the Summa API for the specified SIM card. The exact structure depends on the API response but typically includes one or more IMSI entries linked to the provided ICC ID.
If the node supports binary data output (not explicitly shown in the code), it would represent any non-JSON data returned by the API, such as files or encoded payloads related to the IMSI query.
Dependencies
- Requires an active connection to the Summa API via an API key credential configured in n8n.
- Uses internal helper classes for HTTP requests, state management, and operation resolution.
- The node depends on the
summaApicredential to authenticate requests to the Summa backend service.
Troubleshooting
- Missing or invalid ICC ID: Since the ICC ID is required, ensure it is correctly provided; otherwise, the node will fail to find IMSIs.
- Authentication errors: If the API key credential is missing, expired, or incorrect, the node will not connect to the Summa API. Verify credentials in n8n settings.
- API connectivity issues: Network problems or API downtime can cause request failures. Check network access and Summa API status.
- Unexpected API responses: If the API changes or returns unexpected data, the node might not parse results correctly. Review API documentation and update the node if needed.
