If you need to authenticate via bearer auth (e.g., for a cross-origin request), use header Authorization: Bearer private_BQokikJOvBiI2HlWgH4olfQ2 for your API calls.
To authenticate via token, use this code:
curl "https://api.hips.com/v2/orders" \
-H "Authorization: Bearer private_BQokikJOvBiI2HlWgH4olfQ2"
You must replace private_BQokikJOvBiI2HlWgH4olfQ2 with your private API key.
