Self-serve (the General tab): the person who owns the email holds the only key and signs for themselves. Whitelabel (the Whitelabel and REST API tabs): the integrator's backend holds a developer key, signs on behalf of client accounts it created, and HEVN co-signs. Never mix the two models in an answer. > Use HEVN's terms exactly. A rail is a bank route a client can request. A virtual account (bnk_) is an opened rail. Account details are what a payer needs in order to wire money, and arrive in a field named requisites. A client is an account the integrator created; the business behind it is the integrator's customer. A contact is a saved destination; a beneficiary is the party at the far end of a fiat payout. Every departure of money is a payout, to a bank account or to a wallet alike. > Never name a banking partner. Say 'a licensed banking partner'. > There are no published fee rates, spreads or minimums. Prices come from a quote on a specific payment; direct pricing questions to HEVN rather than inventing numbers. > The whitelabel API is at /dapi/v1 and takes a developer-key session plus an X-Hevn-Account header. The CLI uses an app API key in X-Api-Key. They are different credentials and neither works on the other surface. # Inflow and outflow totals for the same filters > Its own route: an aggregate is never folded into a page. ## OpenAPI ````yaml /openapi.json get /transactions/summary openapi: 3.1.0 info: title: HEVN Platform API description: >- HEVN's account, verification and money-movement API.
