Overview
The Summa node for n8n allows you to interact with the Summa API, specifically targeting telecom-related resources and operations. In this configuration, the node is set up to perform the "Get Camel Info" operation on the HLR Subscription resource. This operation is typically used to retrieve CAMEL (Customized Applications for Mobile network Enhanced Logic) information associated with a given IMSI (International Mobile Subscriber Identity). Such functionality is valuable in telecom environments for querying subscriber data, managing roaming profiles, or troubleshooting network services.
Example use cases:
- Fetching CAMEL subscription details for a mobile user based on their IMSI.
- Automating audits of HLR records for compliance or diagnostics.
- Integrating with other systems that require real-time access to subscriber CAMEL info.
Properties
| Name | Type | Meaning |
|---|---|---|
| Imsi | String | The IMSI (International Mobile Subscriber Identity) of the subscriber to query. Required. |
Output
The node returns a json object containing the CAMEL information retrieved from the Summa API for the specified IMSI. The exact structure of the output depends on the API response, but it typically includes fields relevant to the subscriber's CAMEL profile (such as service keys, trigger detection points, etc.).
Note: If the API supports binary responses, the node may also output binary data, representing files or raw payloads returned by the backend.
Dependencies
- External Service: Requires access to the Summa API endpoint.
- API Credentials: Needs valid
summaApicredentials configured in n8n. - n8n Configuration: Ensure the credential type
summaApiis set up and tested (the node uses a built-in credential test).
Troubleshooting
Common Issues:
- Invalid or missing IMSI: If the "Imsi" property is empty or incorrectly formatted, the API call will likely fail.
- Authentication errors: Incorrect or expired
summaApicredentials will result in authentication failures. - Network issues: Connectivity problems between n8n and the Summa API endpoint can cause timeouts or connection errors.
Error Messages & Resolutions:
- "Missing required parameter: imsi" — Ensure the "Imsi" field is filled with a valid value.
- "401 Unauthorized" — Check and update your
summaApicredentials in n8n. - "API request failed" — Verify network connectivity and the availability of the Summa API service.
