SummaInstall

Overview

The node named "Summa" provides integration with the Summa API, specifically supporting various telecommunication-related resources and operations. For the HLR Subscription resource with the Remove PDP operation, this node allows users to remove a Packet Data Protocol (PDP) context associated with a subscriber identified by their IMSI (International Mobile Subscriber Identity). This is useful in scenarios where a mobile data session needs to be terminated or cleaned up on the network side.

Practical examples include:

• Terminating a subscriber's active data session remotely.
• Managing subscriber sessions during troubleshooting or service changes.
• Automating network management tasks related to subscriber data connectivity.

Properties

Both properties are required inputs when performing the Remove PDP operation on the HLR Subscription resource.

Output

The node outputs JSON data representing the result of the Remove PDP operation. This typically includes confirmation of the removal action, status codes, or any error messages returned by the Summa API. The exact structure depends on the API response but generally confirms whether the PDP context was successfully removed.

There is no indication that the node outputs binary data.

Dependencies

• Requires an API key credential for authenticating with the Summa API.
• Uses an HTTP client internally to communicate with the Summa backend services.
• The node depends on the Summa API version indicated in the node description (v. from the bundled code).
• Proper configuration of the API credentials within n8n is necessary for successful execution.

Troubleshooting

• Common issues:

  • Invalid or missing IMSI or PDP values will cause the operation to fail.
  • Authentication errors if the API key credential is incorrect or expired.
  • Network connectivity issues between n8n and the Summa API endpoint.
  • API rate limits or permission restrictions may prevent successful PDP removal.

• Error messages:

  • Authentication failures usually indicate problems with the provided API credentials; verify and update them as needed.
  • Validation errors related to IMSI or PDP parameters suggest checking the input values for correctness.
  • Timeout or connection errors require checking network access and API availability.

Resolving these issues typically involves verifying input parameters, ensuring valid API credentials, and confirming network connectivity.
