Apex Embedded Components - Enterprise Payment Solutions

Complete reference of all VisaAcceptance SDK methods and instance lifecycle controls.

Initialization

`init(config)`

Initialize the SDK with global configuration. Must be called before render(). Calling it a second time is a no-op and logs a console warning.

VisaAcceptance.init({
  locale: 'en-US',
  theme: { preset: 'anet', mode: 'light' },
  onEvent: (type, payload) => analytics.track(type, payload),
  onError: (error) => errorReporter.capture(error),
});

Prop

Type

Rendering

`render(component, container, config?)`

Mount an embedded component into a DOM element. Returns an EmbeddedInstance for lifecycle control.

const instance = VisaAcceptance.render('transactions', '#my-container', {
  onReady: () => console.log('Component loaded'),
  onAuthRequired: () => refreshToken(),
});

Parameters:

Parameter	Type	Description
`component`	`ComponentName`	One of: `transactions`, `invoices`, `payment`, `pay-by-link`, `subscriptions`, `customers`, `merchant-boarding`, `fraud-manager`, `reports`, `login`
`container`	`string \| HTMLElement`	CSS selector or DOM element reference
`config`	`RenderConfig`	Optional mount configuration

Prop

Type

Runtime Updates

`updateConfig(config)`

Merge partial configuration at runtime. Propagates theme, locale, and permission changes to all live instances.

VisaAcceptance.updateConfig({
  locale: 'fr-FR',
  theme: { mode: 'dark' },
});

Instance Methods

Each render() call returns an EmbeddedInstance:

Method	Returns	Description
`getInstanceId()`	`string`	Unique instance identifier
`getState()`	`ComponentState`	Current lifecycle state
`destroy()`	`void`	Tear down iframe, listeners, and transition to `DESTROYED`
`updateTheme(theme)`	`void`	Push a partial theme update to this instance
`authenticate(config?)`	`Promise<void>`	Trigger re-authentication. Optional `{ timeout }` in ms
`sendToIframe(type, payload?)`	`void`	Send a custom message to the component iframe

const instance = VisaAcceptance.render('invoices', '#container');

// Update appearance
instance.updateTheme({ mode: 'dark' });

// Re-authenticate after token refresh
await instance.authenticate({ timeout: 10000 });

// Cleanup
instance.destroy();

Utility Methods

Method	Returns	Description
`getConfig()`	`VisaAcceptanceConfig \| null`	Current global config snapshot
`getEnvironment()`	`Environment`	Auto-detected: `'local'` \| `'dev'` \| `'cte'` \| `'prod'`
`getVersion()`	`string`	SDK semver string
`getInstances()`	`EmbeddedInstance[]`	All currently mounted instances
`destroyAll()`	`void`	Destroy all instances and reset state

Testing Helpers

These methods are available in all environments but intended for development and testing only.

Method	Description
`init({ noAuth: true })`	Bypass authentication for all components (sandbox mode)
`render(component, container, { noAuth: true })`	Bypass auth for a single component
