Advanced button

This option allows you to direct your client to make a payment using CambioReal with little or no programming needed. We recommend this button for sites that have various types of products and services, which can be accumulated in one purchase. This will work as a shopping cart style checkout. See below:

1. Customer chooses products or services in your store.
2. The form with the CambioReal's checkout button must be inserted in the shopping cart. The customer is directed, along with the purchase data, to CambioReal's website.
3. On CambioReal's website, the customer makes the payment.
4. Customer is redirected back to your site, to a purchase completion page.

HTML Form

In the example you can see an HTML form that directs the buyer to the payment page.

Possible errors:

• Session expired
• Invalid information in HTML form
• Total value less than USD 50.00

Reference

Use the input reference to enter the order reference code to your system. This will be very useful if you want to integrate the backend of your e-commerce with CambioReal, to use our API of query of the status of transactions.

Each transaction generated may be related to a sequential number chosen accordingly to the company's preference, such as the transaction ID or order number.

The use of this parameter is exclusively for internal use of the company. The client does not have access to this information at any point in the checkout process.

The use of this parameter is optional and can be viewed on the transaction details, which can be accessed in the company's account panel, on CambioReal's website.

Configuration

The configuration fields are all optional, some have default values and others have global configuration on the Company Dashboard, in the online account menu.

Base Currency

Use the input currency to set the base currency to perform the payment request calculations.

Default value: USD

Available values: USD, BRL

Session Time

When customers are directed to the CambioReal website, by default, they have 30 minutes to generate the transaction, if they exceed this time, the client will be redirected to url url_error defined above.

Some e-commerces work with time-limited promotions and end-of-stock products, in which they limit and decrease the client's session time to avoid that the client makes a payment of product that has been sold out during a long session, so it is recommended to shorten this time.

CambioReal's Direct API works with any kind of e-commerce, by seamlessly connecting with your shopping cart. When a customer chooses CambioReal's payment method, it will be redirected to the external checkout where very quickly it can complete the payment. Once the customer has completed all fields and successfully paid the order,it will be redirected back to your store.

• Get Transaction Data
• Cancel Payment Request
• Amount Calculator
• Status Notification

Authentication

Authentication in our API is performed in 3 steps to ensure greater security and convenience in transactions:

1. The client's APP ID is first validated.
2. The client's APP SECRET is verified, if it is valid and matches the registration.
3. And lastly, it is validated if the received request comes from an IP or Hostname / Domain identical to the one registered by the client in the panel.

Acquiring your credentials

1. Access CambioReal for business Dashboard.

2. Go to Integration.

   

3. Then click on the Direct API tab.

   

4. Fill in the fields with the corresponding data.

   • Developer name: Person responsible for integrating magento with cambioreal.
   • Developer e-mail: The e-mail we will send instructions and credentials.
   • Select the bank account in which you would like to receive your payments: All payments made through this button will be sent to this account.
   • Select the type of address to restrict access from your website to our API: The authentication will be made via ip or hostname/domain of your website. E.g.: Website IP: 54.208.129.87 / Website Hostname: cambioreal.com
   • Notification URL: It is through this url that our server will send a notification informing that your transactions status changed in our payment system. Format: https://{YOUR_SITE}/cambioreal/payment/notify

Status Notification

With the notification URL set when creating credentials, you can receive notifications from our system every time a transaction changes its status. Our system only sends the transaction identifiers, id and token, the status query should be done upon receipt of the notification.

When your system receives a notification at the configured URL, it should respond with HTTP 200 status so that our system understands that the notification was received correctly. If not, our system will try to notify you two more times.

We recommend saving the data received from notifications and creating a standalone process that performs status queries so that it does not affect performance or data is lost when the notification process runs.

Example Notification:

{
    "id": 530,
    "token": "e82b97cf652e91344f86510907b32daa5df8f13fdda41"
}

Notification data is sent via POST using Content-Type: application/x-www-form-urlencoded, and has the following fields:

To check the transaction status, simply query the transaction data using the method already cited above, Get Transaction Data.

Possible statuses for a transaction:

• PENDENTE_ACCOUNT - Company bank account is pending approval.
• AGUARDANDO_CLIENTE - Waiting for customer to generate the transaction.
• BOLETO_GERADO - Transaction generated.
• BOLETO_EXPIRADO - Transaction expired.
• BOLETO_CANCELADO - Transaction canceled.
• SOLICITACAO_RECUSADA - Customer declined the payment request.
• SOLICITACAO_INVALIDA - Invalid payment request.
• SOLICITACAO_CANCELADA - Company canceled the payment request.
• SOLICITACAO_PAGO - Payment request paid.
• SOLICITACAO_FINALIZADA - Payment request sent for payment to beneficiary.
• SOLICITACAO_EXPIRADA - Payment request expired.
• REFUND_REQUESTED - Refund requested.
• REFUNDED - Refund executed.

Update transaction status for testing

So far, the only test scenarios available are BOLETO_EXPIRADO and SOLICITACAO_PAGO. After the payment request is generated, you must create a transaction in our checkout before requesting a status change.

PUT /service/v1/checkout/{token}

Setup

To use the CambioReal PHP library you need to setup your app id and app secret.

<?php

\CambioReal\Config::setAppId('your-app-id');
\CambioReal\Config::setAppSecret('your-app-secret');

If you need to change other settings, you can use the following function call:

<?php

require_once __DIR__ . '/../src/autoload.php';

\CambioReal\Config::set([
    'appId'      => 'your-app-id',
    'appSecret'  => 'your-app-secret',
    'testMode' => true,
]);

You can change the following settings:

• appId: your app id. It will be different in test and production modes.
• appSecret: your app secret. It will be different in test and production modes.
• testMode: enable or disable the test mode. The default value is false.

To create a new API request, just call one of the following methods on the \CambioReal\CambioReal class and supply it with the request parameters:

• \CambioReal\CambioReal::cancel
• \CambioReal\CambioReal::get
• \CambioReal\CambioReal::request

Request and Payment

With the library installed and configured, you must call the method \CambioReal\CambioReal::request, which will create a payment request in our system and return the redirect URL for your customer to access our checkout where they will make the payment.

In this step you should also enter the return URL to your site (url_callback field) where the customer will be directed after payment.

Example Request:

{
  "url_callback": "https://seudominio.com/callback_cambioreal_success", // URL to return to when the customer successfully pays.
  "url_error": "https://seudominio.com/callback_cambioreal_error", // URL to return to when an error occurs in the payment process.
  "client": {
    "name": "John Test",
    "email": "john@test.com"
  },
  "currency": "USD",
  "amount": 1605.0,
  "order_id": "_your_control_number_",
  "duplicate": 0, // Allow to customer generate another transaction after expiration. Not required, if not informed the account configuration will be used.
  "due_date": 1, // Number of days the payment request will be valid to. It's not mandatory.
  "products": [
    {
      "descricao": "Laptop i7",
      "base_value": 800.0,
      "valor": 1600.0,
      "qty": 2,
      "ref": "_your_control_number_for_the_product_"
    },
    {
      "descricao": "Frete",
      "base_value": 5.0,
      "valor": 5.0,
      "ref": "São Paulo - SP"
    }
  ]
}

Notification and Status

This is how our proccess of notification of status change happens:

When a transaction changes status in our system, it notifies your site via a form-data POST by informing the transaction id and token.

Your application will receive this data as a normal POST, as if receiving data from a form (form-data, not json or xml):

• $request->input('id');
• $request->input('token');

With this information it's possible to make a query through our API to request what is the current status.

In the response received from this query you can identify what is the transaction within your system through the reference passed at the time the request was generated.

Example of data sent in notification:

{
  "id": 5,
  "token": "88ba76feb3b6623e6aaa03d88e1620f55a9d4b8790500"
}

To query the notified transaction status, use the get method, which performs a GET request to endpoint /service/v1/checkout/get/{YOUR_TOKEN}, where {YOUR_TOKEN} is the identifier of the transaction to query.

Example query response from a transaction:

{
  "status": "success",
  "message": null,
  "errors": null,
  "data": {
    "id": 5,
    "token": "88ba76feb3b6623e6aaa03d88e1620f55a9d4b8790500",
    "code": "BRSL03051005",
    "ref": null,
    "currency": "USD",
    "amount": 150,
    "take_rates": false,
    "duplicate": false,
    "expired": false,
    "expires_in": null,
    "expires_at": null,
    "status": "BOLETO_GERADO",
    "created_at": "2019-03-13 11:20:07",
    "payment_method": "boleto"
  }
}

The ref field will be the order reference within your system previously passed through the field order_id in the creation of the request.

Amount simulator

The customer sees the simulation in our checkout, but if you want to make it available on your system there is an endpoint to it.

To perform a simulation of values, call the \CambioReal\CambioReal::simulator method or send a request using the POST method to endpoint /service/v1/checkout/simulator.

Simulation Example:

{
  "currency": "USD", // Simulation Currency
  "amount": 30, // Amount to be converted
  "take_rates": 1, // Option if the company wants to assume the fees (shipping fee, iof, ...)
  "payment_method": "boleto" // Payment Method (boleto, ted)
}

Example of the response received:

{
  "status": "success",
  "message": null,
  "errors": null,
  "data": {
    "currency": "USD",
    "amount": 30, // Amount requested
    "price": 13.87, // Total cost price (taxes)
    "fee": 1.99, // USD service fee charged
    "method_fee": 3.95, // Amount charged in BRL according to payment method
    "iof": 1.3613, // IOF to be paid
    "iof_percentage": 1.1, // IOF percentage (1.1%)
    "rate": 4.3023, // Rate of the moment
    "result": 129.07, // Total Conversion Amount
    "vet": 4.81964 // VET (Total Effective Value)
  }
}

4. Woocommerce Settings

In some cases, Woocommerce orders automatically expire after some period if not paid. This happens if inventory management is enabled on the platform, to get around this problem, you must disable the "Hold stock" timeout or increase it to a considerable amount of time. But beware, boletos can take up to 3 business days to be paid, so if you are using this payment method, it is important to disable this Woocommerce automation.
