Hi ERPnext Developers,
I customize the ERPnext for full GYM Management, and complete work,
I use the Customer Doctype in ERPnext as GYM Member,
Ever Member has Expire Date of Subscription, and We have Automatically Open Door, is Open by Member Card, (Old System Not ERPnext),
But now we want to Use and Integrate ERPnext with those door, how we can do this ?
