How to send form data in ReactNative web view?

Question

I want to send form data values to my webview url before it loaded. I'm getting this values from redux.

This is what I tried. But It's not working

    let token=this.props.usersData ? this.props.usersData.token : null
    let currencyValue=this.props.usersData ? this.props.usersData.currencyValue :null
    let paymentValue=this.props.usersData ? this.props.usersData.paymentValue : null

    let formdata = new FormData();

    formdata.append("token", token)
    formdata.append("currencyValue", currencyValue)
    formdata.append("paymentValue", paymentValue)

    return (
        <WebView
            style={styles.webView}
            scrollEnabled={true}
            source=
            {{uri: 'https://myweb.com/tokenization?type=datasave&test=yes', 
            headers: { 'Content-Type': 'application/x-www-form-urlencoded', body:formdata }}}

        />

    );

Please note that props values are getting without any issue (no null values there)

You must use injectedJavaScript and pass a string, try this:

return (
    <WebView
        style={styles.webView}
        scrollEnabled={true}
        source={{ uri: 'https://myweb.com/tokenization?type=datasave&test=yes' }}    
        injectedJavaScript={`window.token=${token}; window.currencyValue={currencyValue}; window.paymentValue=${paymentValue}`}
    />

);

then in your myweb.com you can get this variables with window.token , window.currencyValue , window.paymentValue
