Loading HyperSwitch

The main function, loadHyper, dynamically loads the HyperSwitch SDK and initializes it with analytics metadata.

Syntax

const hyperPromise = loadHyper("YOUR_PUBLISHABLE_KEY", {
  customBackendUrl: "YOUR_BACKEND_URL",
  // You can configure this as an endpoint for all the api calls such as session, payments, confirm call.
});

str: A string representing your public key.
option: Optional configuration object (option<JSON.t>).

Example

loadHyper("YOUR_PUBLISHABLE_KEY", None)
->then(instance => {
  // Use the instance for further operations
})
->catch(err => {
  console.error("Failed to load Hyper:", err)
})

Deprecated Function: `loadStripe`

The function loadStripe is deprecated and will be removed in future versions. It is a wrapper around loadHyper with a warning. Please use loadHyper instead.

Example

loadStripe("YOUR_PUBLISHABLE_KEY", None);

Warning: This function will log a deprecation message in the console.

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.
