OrderID variable

When a customer purchases a plan, what kind of variable is generated like OrderID, and how could we use this to pass it back to a 3rd party system we are using?

Hello

There are many information available like ID of the subscription record, plan id, first name, last name, email, amount, discount amount, tax amount, gross amount

You can look at #__osmembership_subscribers table to see all fields stored in database for each subscription.

If you want to pass this information to third party, you will have to develop a plugin to send the data to the services you want
