Hi all, we are building remote teams bonding platform called Karma (https://karmabot.chat) and planning to hook up Karma Rewards to gift cards through some neat API. Ideally, it should be as simple and pleasant as working with Stripe API. If you had any experience with that, which API should we use:<p>- https://business.gyft.com/gift-card-catalog/<p>- https://www.tangocard.com/gift-card-api/<p>- https://flexawards.com/api/digital-gift-card-api<p>- https://tremendous.com/products/gift-cards<p>- https://www.rybbon.net/pricing/<p>Other suggestions?<p>Note: most of Karma's teams are in the US, but at least a 1k of them is elsewhere. It would be preferable to have at least some cards available to them.
