Paypal subscription based licensing

Hi,

I am using Paypal+LimeLM solution for selling a perpetual license to our customers. Now, we require a scheme where users can pay monthly. I have gone through your article about creating a custom field - update_expires.

What I am not sure is the interaction between paypal and LimeLM. How and who will update "update_expires" variable on paypal confirmation ?

Many thanks.

You will set the "update_expires" custom license field. See the examples for how to set the custom license field as part of the product key generation.

To do a renewal form you can either modify that existing payment form (letting it accept new orders or renewals) OR create a separate renewal form where the customer enters their product key OR do automatic renewals using PayPal's API.
