v5.1.1

As of 2020-05-30, Amplitude reported issues with their SSL certificate, so they set up an endpoint and alternate endpoint at https://api2.amplitude.com. Read about it on Amplitude's Status Page and affected devices here.

• Add option to set token endpoint via an environment variable, i.e. AMPLITUDE_TOKEN_ENDPOINT="https://api2.amplitude.com"
• Add option to set token endpoint via constructor options, i.e. https://api2.amplitude.com

v5.0.2

• Convert to typescript (this shouldn't break anything as it's being exported just like before)
• Implement the Amplitude HTTP V2 API

IMPORTANT: There aren't any breaking changes in the code, but the Amplitude V2 API has a few stricter validations server side. For example, in one project where I was using this, I was passing a timestamp generated from Swift, so it was a float. However, the time param only allows type of long, i.e. integer.

From Amplitude's docs:

• Validation on Content-type header (must be set to application/json)
• Validation on proper JSON request body
• Validation on event_type name (cannot be event names that are reserved for Amplitude use)
• Validation on device_id length (must be 5 or more characters unless overrided with min_id_length)
• Validation on user_id length (must be 5 or more characters unless overrided with min_id_length)
• Validation on time field in event payload (must be number of milliseconds since the start of epoch time)
