The Web SDK targets first-party browser apps. It ships with TypeScript types for autocomplete and inference. The SDK is tested against the latest versions of:
  • Chrome (Desktop, iOS, Android)
  • Safari (macOS)
  • Safari (iOS)
  • Firefox
Building a React Native app? Use the React Native SDK instead. For iOS, Android, or Flutter, drive frames directly — see the manual integration overview.

​
Install

Install the SDK package: 
pnpm i @moonpay/platform-sdk-web

​
Result<T, E>

Most SDK functions return a Result<T, E> instead of throwing.
FieldTypeRequiredDescription
okboolean✅Whether the operation succeeded.
valueTPresent when ok is true.
errorEPresent when ok is false.
Use this pattern to branch on success vs failure: 
const result = await someSdkCall();

if (!result.ok) {
  // Handle error
  console.error(result.error);
  return;
}

console.log(result.value);
