According to Mixpanel's API documentation here: https://mixpanel.com/docs/api-documentation/exporting-raw-data-you-inserted-into-mixpanel
Method: export
URI: https://data.mixpanel.com/api/2.0/export/
Please note: The URI is data.mixpanel.com and not just mixpanel.com
Description
Get a "raw dump" of tracked events over a time period.
Parameters
...
optional event array
The event or events that you wish to get data for, encoded as a JSON array.
Example format: '["play song", "log in", "add playlist"]'
An expression to filter events by. See the expression section on the main data export API page.
...
If I wanted to fetch all events rather than a list of specific events, is there a wildcard syntax that I can use?
Mixpanel support answered my question, if you omit the "events" parameter it will return all types of events:
eg: API call, notice there is no event parameter included

Events of all types will be returned since no "event" filter is specified.
