Authentication

The Voucherly API uses API keys to authenticate requests. Sandbox mode secret keys have the prefix sk_sand_ and live mode secret keys have the prefix sk_live_. You can view and manage your API keys in the Voucherly Dashboard.

Your API keys carry many privileges, so be sure to keep them secure! Do not share your secret API keys in publicly accessible areas such as GitHub, client-side code, and so forth.

Provide your API key as the "Voucherly-API-Key" header. For example:

-H  "Voucherly-API-Key: sk_sand_BYsZDnaUWfVKGwHFvLop0dc9Fp1mE8py2Mtgm5aU6IrtCiuJg9s4747J"

All API requests must be made over HTTPS. Calls made over plain HTTP will fail. API requests without authentication will also fail.
