SummaInstall

Overview

The node named "Summa" integrates with the Summa API (version indicated in the node description) to perform various operations on different resources. Specifically, for the HLR Subscription resource and the Remove USSD Profile operation, this node allows users to remove a USSD profile associated with a subscriber identified by their IMSI (International Mobile Subscriber Identity). This is useful in telecom environments where managing subscriber profiles and services dynamically is required.

Practical examples include:

• Removing outdated or incorrect USSD profiles from subscriber accounts.
• Automating subscriber profile management as part of a larger workflow for telecom service provisioning or deprovisioning.
• Integrating with backend systems to maintain up-to-date subscriber data without manual intervention.

Properties

Output

The node outputs JSON data representing the result of the Remove USSD Profile operation. This typically includes confirmation of success or failure, status codes, and any relevant messages returned by the Summa API. The exact structure depends on the API response but generally confirms whether the USSD profile removal was successful.

No binary data output is indicated for this operation.

Dependencies

• Requires an active connection 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.
• Proper credentials must be set up in n8n to authenticate requests to the Summa API.

Troubleshooting

• Common issues:

  • Invalid or missing IMSI value: Ensure the IMSI provided is correct and formatted properly.
  • Authentication failures: Verify that the API key credential is valid and has necessary permissions.
  • Network or connectivity errors: Check network access to the Summa API endpoint.
  • API errors due to invalid state or non-existent USSD profile: Confirm that the USSD profile exists before attempting removal.

• Error messages:

  • Authentication errors usually indicate problems with the API key; reconfigure or update credentials.
  • Validation errors related to IMSI suggest checking the input value.
  • HTTP errors from the API may require reviewing API documentation or contacting support.

Links and References

• Summa API official documentation (refer to your organization's internal or public API docs).
• n8n documentation on creating and using API credentials.
