The host is the address of the Legitimuz API.
Example: `https://api.legitimuz.com`
The token is your integration token. You can generate an integration token on the
[integrations](https://dashboard.legitimuz.com/dashboard/integrations) page under the `installation` tab in the Legitimuz Dashboard.
The `lang` option sets the language that will be used in the [OCR + Facematch validation](/sdk-reference/legitimuz/ocr-facematch) flow.
The `enableRedirect` option is a boolean that defines whether, after the [OCR + Facematch validation](/sdk-reference/legitimuz/ocr-facematch) flow, the user will be redirected to the link registered in the Legitimuz Dashboard.
The `autoOpenValidation` option is a boolean that defines whether the `popup` for [OCR + Facematch validation](/sdk-reference/legitimuz/ocr-facematch) will automatically open after entering a value in the [cpf input](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/Input).
A opção balanceValue é o valor do saldo do usuário.
```html HTML theme={null}
```
```jsx JSX theme={null}
import { useRef } from 'react';
function Component() {
const sdkInstance = useRef(null);
const handleOnLoadSDK = () => {
sdkInstance.current = Legitimuz({
/* options */
balanceValue: 123,
});
sdkInstance.current.mount();
}
return (
<>
);
}
```
A opção withdrawValue é o valor do saque do usuário.
```html HTML theme={null}
```
```jsx JSX theme={null}
import { useRef } from 'react';
function Component() {
const sdkInstance = useRef(null);
const handleOnLoadSDK = () => {
sdkInstance.current = Legitimuz({
/* options */
withdrawValue: 123,
});
sdkInstance.current.mount();
}
return (
<>
);
}
```
The success callback is triggered when `success` occurs at any stage of the [OCR + Facematch validation](/sdk-reference/legitimuz/ocr-facematch) flow. A [string](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String) with the stage where success occurred is passed as a parameter.
Examples:
```html theme={null}
```
```jsx theme={null}
import { useRef } from 'react';
function Component() {
const sdkInstance = useRef(null);
const handleOnLoadSDK = () => {
sdkInstance.current = Legitimuz({
/* options */
onSuccess(eventName) {
console.log(eventName); // ocr | facematch
},
});
sdkInstance.current.mount();
}
return (
<>
);
}
```
The error callback is triggered when an `error` occurs at any stage of the [OCR + Facematch validation](/sdk-reference/legitimuz/ocr-facematch) flow. A [`string`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String) with the stage where the error occurred is passed as a parameter.
Examples:
```html theme={null}
```
```jsx theme={null}
import { useRef } from 'react';
function Component() {
const sdkInstance = useRef(null);
const handleOnLoadSDK = () => {
sdkInstance.current = Legitimuz({
/* options */
onError(eventName) {
console.log(eventName); // ocr | facematch
},
});
sdkInstance.current.mount();
}
return (
<>
);
}
