Development suggestions
We recommend that you use the V3 SDK to make calls.
Making direct API calls is not recommended because the process is complex and involves handling multiple request parameters and a signing mechanism.
V3 introduces features for multiple subject identification and similarity scores. You can obtain these results using the SDK. For more information, see the SDK code examples.
