If you do not own a Gladia API key yet, get yours by following our Account Setup guide.

Once you got your API key, to authenticate, you just need to pass it in the header keys, just like this:

curl --request GET \
  --url https://api.gladia.io/v2/transcription \
  --header 'x-gladia-key: YOUR_GLADIA_API_KEY'

The header authentication method ensure that you are able to use Gladia in any environment or any cloud-based third party service.

This is the only authentication method you’ll need to use all the API endpoints.

Next, we’ll see what’s the general transcription flow and how to manage it on your side.
