Issue description

After calling dropin.create() function the drop-in is created successfully but in the Network tab of dev tools I see a POST request to https://api2.amplitude.com/2/httpapi with response code 400 and response body as
{
"code": 400,
"error": "Invalid API key: a23fb4dfae56daf7c3212303b53a8527"
}

Here is the request body
