Features

- Dynamically loads the HyperSwitch SDK based on the environment (Sandbox or Production).
- Ensures that only a single script instance is added to the page.
- Provides an easy-to-use promise-based API.

Script URLs

The script URL is determined based on your environment and key:

- Sandbox: https://beta.hyperswitch.io/v1/HyperLoader.js
- Production: https://checkout.hyperswitch.io/v0/HyperLoader.js
- Fallback: Determines based on the prefix of the provided key (pk_prd_).

Integration Warnings

The loadHyper function ensures that the HyperLoader.js` script is added only once to the page. Adding multiple script tags may lead to unexpected behavior. If a script is already present, the function will issue a warning and use the existing script.
