## Notes



* API Key is like a password to your account. You must never send this information to browser or application clients. Also, do not publish your API Key in publicly accessible areas such as Git repositories, Android/iOS clients, support forums, etc..
* Use [https://sandbox.juspay.in](https://sandbox.juspay.in) endpoint for testing on the staging server.
* For the full set of our API please go through [https://docs.juspay.in/api-reference](https://docs.juspay.in/api-reference).
* To get **auth_account_id**  you have to set up your authentication provider detail with us. Please update provider’s credential at [https://merchant.juspay.in/settings/direct-acs](https://merchant.juspay.in/settings/direct-acs) and use the “Account Id” generated by us as auth_account_id while initiating OTP request.
* To get the list of gateway_id visit this [http://faq.juspay.in/15704-express-checkout/ec_pa_gateway_id](http://faq.juspay.in/15704-express-checkout/ec_pa_gateway_id).
* Since these API’s are authenticated all non-PCI-DSS certified merchants should use card tokenization to handle card data.
