# Call Studio API

#### Uploading recordings through API

The upload process consists of three steps. After all three steps are completed, you will see the recording in Call Studio and analysis will be completed shortly.

#### 1. Requesting a signed URL

```bash
curl --location --request POST 'https://voicehub.dataqueue.ai/api/v1/playground/signed-url?fileName=file.wav' \
--header 'x-dq-api-key: YOUR_API_KEY_HERE'
```

The request returns a JSON object:

```json
{
    "url": "example-signed-url.com"
}
```

#### 2. Upload the file to cloud storage

Using the URL obtained in the previous step, upload your file using a PUT request:

```
curl --location --request PUT 'example-signed-url.com' \
--header 'Content-Type: audio/wave' \
--data-binary '@/path/to/your/file.wav'
```

#### 3. Request analysis of the uploaded file

Once step 2 is complete, you can request Call Studio analysis of your recording:

```
curl --location 'https://voicehub.dataqueue.ai/api/v1/playground/api-analysis' \
--header 'x-dq-api-key: YOUR_API_KEY_HERE' \
--header 'Content-Type: application/json' \
--data '{
    "fileName": "file.wav",
    "title": "Example Title"
}'
```

The `fileName` parameter must match the `fileName` given in step 1, otherwise the analysis will fail. The `title` field will be shown in the Title column of Call Studio.
