Matching accuracy depends on which parameters you provide — the more identifying data included, the higher the confidence.
Applies to: Signal API
Answer
The accuracy achieved depends on the specific data and parameters provided when using the Signal API.
For higher accuracy:
- Scoping down to an advertiser or campaign, if that data is available, improves accuracy.
- Providing Caller ID is recommended, though not mandatory — accuracy is lower if only the start time is provided without Caller ID.
- Including call duration as a parameter can also improve accuracy.
For the highest level of accuracy:
- Provide the call ID or transaction ID in the API request.
- If neither is available, combine start time, Caller ID, and duration — this combination is likely to produce very accurate matching.
