The Banco Inter PHP client provides convenient access to the Banco Inter API from applications written in the PHP language.

Other languages

Requirements

PHP 7.4.0 and later.

Composer

You can install the package via Composer. Run the following command:

composer require potelo/inter-php

Or simply add it to your composer.json dependences and run composer update:

"require": {
    "potelo/inter-php": "dev-main"
}

To use the client, use Composer's autoload:

require_once 'vendor/autoload.php';

Dependencies

The library require the following extensions in order to work properly:

• Guzzle
• json

If you use Composer, these dependencies should be handled automatically. If you install manually, you'll want to make sure that these extensions are available.

Usage

• Getting Authorization
• Bank Slip
• Immediate Charge
• Pix

Getting Authorization doc

$privateKey = 'you-private-key-path.key';
$certificate = 'you-certificate-path.crt';
$clientId = 'you-client-id';
$clientSecret = 'your-client-secret';

$client = new \Potelo\InterPhp\InterClient($privateKey, $certificate, $clientId, $clientSecret);

$scopes = ['cob.read'];
$client->authorize($scopes);

You can get new token with new scopes using the same client instance:

$scopes = ['cob.read', 'cob.write', 'pix.read', 'pix.write'];
$client->authorize($scopes);
