Versapay Authentication API

Visit your account settings in `UAT` (https://uat.versapay.com/account) or `Production` (https://secure.versapay.com/account) to setup API credentials needed for authentication as well as webhooks to receive relevant callbacks from Versapay transaction processing. You can generate/disable your API credentials as often as necessary for security reasons. If you do not have an account, please contact Versapay Support for support & setup of AR invoicing integration, hosted checkout and/or payment acceptance for partner and/or API credential setup. ## API Token and API Key API requests are authenticated using `API Token & Key` via [HTTPS Basic Access Authentication](https://en.wikipedia.org/wiki/Basic_access_authentication). Security Scheme Type HTTPS HTTPS Authorization Scheme basic Simply provide the `API Token & Key` values as the `user` and `password` parameters, using cURL for instance: `curl -u "Nvax...:UN0I..." -X POST https://secure.versapay.com/api/...` ## JWT Token Alternatively, API requests can also be authenticated using `JWT Token` via [HTTPS Bearer Authentication](https://en.wikipedia.org/wiki/JSON_Web_Token).
