Overview

This node integrates with the Summa API to perform various telecommunication-related operations. Specifically, for the MSISDN resource and the Find MSISDN Of IMSI operation, it retrieves the MSISDN (Mobile Station International Subscriber Directory Number) associated with a given IMSI (International Mobile Subscriber Identity). This is useful in scenarios where you have an IMSI identifier and need to find the corresponding phone number.

Practical examples include:

  • Telecom operators looking up subscriber phone numbers based on their IMSI.
  • Systems that manage SIM cards or mobile subscriptions needing to correlate IMSI and MSISDN data.
  • Fraud detection or subscriber management platforms verifying subscriber identities.

Properties

Name Meaning
Imsi The IMSI (International Mobile Subscriber Identity) string for which the corresponding MSISDN is to be found. This is a required input.

Output

The node outputs JSON data containing the MSISDN information related to the provided IMSI. The exact structure depends on the Summa API response but typically includes fields such as the MSISDN number and possibly additional metadata about the subscriber or subscription.

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

Dependencies

  • Requires access to the Summa API via an API key credential configured in n8n.
  • The node uses an HTTP client internally to communicate with the Summa backend service.
  • Proper configuration of the Summa API credentials within n8n is necessary for successful execution.

Troubleshooting

  • Common issues:
    • Invalid or missing IMSI input will cause the operation to fail.
    • Incorrect or expired API credentials will result in authentication errors.
    • Network connectivity problems can prevent communication with the Summa API.
  • Error messages:
    • Authentication failures usually indicate invalid API keys; verify and update credentials.
    • "Resource not found" or similar errors may mean the IMSI does not exist in the system.
    • Timeout or connection errors suggest network issues or API downtime.

Resolving these typically involves checking input values, ensuring valid credentials, and confirming network access.
