I want to check for the date in which a user had subscribed to plan for the first time.
Example:
I subscribed on 15th of November
I get charged on 15th of December
I get charged again on the 15th of January
When I retrieve a subscription I get the “start_date” but that is the start day of the current billing period (e.g. 15th of January) or is that the 15th of November?
