    signature={signature}
    dataString={payload}
    callback={(data: any) => {
        console.log(JSON.stringify(data));
    }}
/>
```

### How to make a payment?

1. first select stage - ```IPGStage.DEV / IPGStage.PROD```
2. Create payment **payload** & **signature** from Server-side and parse signature and base64 encoded payload to *IPGComponent*

    *Note: it's the best practice to create payload and signature from server side. otherwise the data will be compromised.*

#### payload
Payload is a base64 encoded string that created from JSON payload string. Here is a sample object,
```js
payload = {
   merchant_id : "xxxxxx",
   amount : "10.00",
   type : "ONE_TIME",
   order_id : "CP123456789",
   currency : "LKR",
   response_url : "https://test.com/response-endpoint",
   first_name : "Sam",
   last_name : "Perera",
   email : "user@email.com",
   phone : "0712345678",
   logo : "",
};
```
#### signature
Signature is HmacSHA256 hash of the base64 encoded payload string. The **secret** for HmacSHA256 can be found at developer portal.

```js
createHmacSha256Hash(base64jsonPayload, secret);
```

Provide these two arguments to IPGComponent and you'll receive the reponse from *callback* function.
