Add Card - Send Out Cards
Sendout Cards decided to no longer keep their API public and instead keep everything in house. Therefore, our affiliation with Sendout Cards has ended, we are working to remove it off of our system while we search for a suitable replacement. Our apologies for any confusion or inconvenience.
