Examples

See the examples folder for complete source code examples using both the useTellerConnect hook and the <TellerConnect /> component.

Using React hooks

Hooks are the recommended method of integrating with Teller Connect in React.

ℹ️ See a how to use the userTellerConnect hook in hook source code example (examples/hooks.tsx)

import { useTellerConnect } from 'teller-connect-react';

// ...

const { open, ready } = useTellerConnect({
  appId: "YOUR_APPLICATION_ID",
  onSuccess: (authorization) => {
    // Save your access token here
  },
});

return (
  <button onClick={() => open()} disabled={!ready}>
    Connect a bank account
  </button>
);

Available configuration options

ℹ️ See src/types/index.ts for exported types.

The Teller Connect Guide remains the canonical reference of Teller Connect's capabilities and supported configurations.

Presenting Teller Connect without user interaction

To present Teller Connect without any user interaction, e.g. immediately when your view is rendered you can use an effect.

import { useTellerConnect } from 'teller-connect-react';

// ...

const { open, ready } = useTellerConnect(config);

// Present Teller Connect immediately on load
React.useEffect(() => {
  if (ready) {
    open();
  }
}, [ready, open]);

return <></>;

Using the pre-built component instead of the useTellerConnect hook

Although the useTellerConnect hook is the recommended integration method a pre-built component is made available if you're unable to use hooks in your application.

ℹ️ See the example at examples/component.tsx

import { TellerConnect } from "teller-connect-react";

const App extends React.Component {
  // ...
  render() {
    return (
      <TellerConnect
        className="CustomButton"
        style={{ padding: '20px', fontSize: '16px', cursor: 'pointer' }}
        applicationId={this.state.appId}
        onSuccess={this.onSuccess}
        onEvent={this.onEvent}
        onExit={this.onExit}
      >
        Link your bank account
      </TellerConnect>
    );
  }
}
