Add subscription data field: sequence number of subscription renewal
I use WooCommerce, WooCommerce Zapier and Learndash.
What I would like to do is for every subscription renewal add an additional product (course) to a persons account. So:
1. Initial purchase: course A (this happens already via the WooCommerce product set up)
2. First Renewal: add course B (I am currently doing this via Zapier using the Subscription Renewed trigger)
3. Second Renewal: add course C (this does not work via Zapier at the moment because the renewal email/product name is exactly the same as for the first renewal, meaning Zapier cannot distinguish between the two)
4. And so on
Is there a way to make sure that for the second renewal course C is added, that is not solely based on the product SKU as I have done at the moment, but rather on the sequence number of renewals.
