Hi how do I sell a merchandise with license key? Ie when the client purchase the product, the pin or key is emailed to him upon payment?

How do I set up something like this?

We have built custom integration plugins here for this, which are not yet ready for sale.

However if you have constant license-keys, or ones which are in e.g. hidden CB-fields, you can do that in the emails of CBSubs or with Emails-integrations plugin using cb substitutions to give the key.
