Gave integrator API

Cashback for stablecoin cards. You send your users' card transactions; Gave computes their rewards from your programs, reserves them in your vault, and tells you with signed webhooks.

Authenticate every request with your API key, in the x-api-key header. Retry a request that failed, unchanged: the same request again changes nothing, except a secret rotation, which makes a new secret each time. Amounts are integers in strings, in the currency's or the token's smallest unit.
