# Make Request

{% hint style="warning" %}
All responses to requests are in the form of objects with the format depending on the [bank's service provider.](https://php-snap-bi.gitbook.io/docs/the-basics/broken-reference)
{% endhint %}

Before use this `SnapBi` make sure to setup [configuration](https://php-snap-bi.gitbook.io/docs/getting-started/configuration#register-config).

```php
<?php

use Otnansirk\SnapBI\Services\SnapBi;
...

$snap = SnapBi::bca();

// Or use chaining method
$snap = SnapBi::for('bca');
```

Actually, apart from the `bca` method and key, there are still several banks that can be used later. Take a look at the [bank support currently available.](https://php-snap-bi.gitbook.io/docs/introduction#bank-support)&#x20;

So, the method or key params `for` method depend on key of  [bank support currently available.](https://php-snap-bi.gitbook.io/docs/introduction#bank-support)&#x20;

### Headers

Headers may be added to requests using the `withHeaders` method. This `withHeaders` method accepts an array of key / value pairs:

```php
SnapBi::bca()->withHeaders([
    "X-EXTERNAL-ID" => "111111"
]);
```

The `withHeaders` method merges new headers into the request's existing headers.

### Body

Body may be added to requests using the `withBody` method. This `withBody` method accepts an array of key / value pairs:

```php
SnapBi::bca()->withBody([
    "X-PARTNER-ID" => "111111"
]);
```

The `withBody` method merges new body into the request's existing body.

### Call available method

```php
SnapBi::bca()
->withHeaders([
    "X-EXTERNAL-ID" => "111111"
])
->withBody([
    "X-PARTNER-ID" => "111111"
])
->vaInquiry();
```
