Get Started

This guide describes how to get started with the Call Score API.

Before you start

Before you use the API, you must generate an access token. For more information, see Authenticate
The transcript needs to be at least 50 words or longer in order to qualify for call-score processing

Process a conversation

Use the Async API to process a recorded text, audio, or video conversation. You can use following attributes to use Call Score behavior for your business use case.

For additional Async API settings, see the API reference documentation.

features: Enable callScore and insights features to generate the call score.

scorecard: Enables you score the conversation on custom criteria. To learn more about criteria, refer here.

{
    "features": {
        "featureList": ["callScore", "insights"],
        "callScore": {
            "scorecardId": "5463513598865445"
        }
    }
}

metadata: Provide additional context about a call such as sales stage to customize call score algorithm. When setting salesStage, the value must be lowercase. You can choose salesStage as qualification, discovery, demo, negotiation, and general.

{
    "metadata": {
        "salesStage": "qualification",
        "prospectName": "DeepMind AI" 
    }
}

conversationType: Set as sales for sales calls and general for other types of calls.
