In the first step an iFrame is created, which serves the purpose of sending credit card information to the Espago Gateway. It then fetches the credit card token and submits it to a form.
You can use a mock credit card: 4242 4242 4242 4242, with the expiry date of 02/2025. The CVV code does not matter.

<!-- iFrame Configuration -->
<script 
  async=""
  data-id="EspagoFrameScript"
  data-key="VrYVaA1CjmRooKh63YYv"
  data-live="false"
  data-button="Pay"
  src="https://js.espago.com/iframe-1.0.js">
</script>

<!-- Form with the credit card token -->
<form id="espago_form" 
      action="/charge_client" 
      accept-charset="UTF-8" 
      method="post">
</form>

Next, the true request is sent to the Espago gateway. It consists of user information, the charged amount and currency among other information. Card input contains the credit card token generated by the IFrame.

curl -i https://sandbox.espago.com/api/charges \
 -H "Accept: application/vnd.espago.v3+json" \
 -u ms_771eUTliRiZ:SeCreT_P@ssw0rD \
 -d "amount=10" \
 -d "currency=pln" \
 -d "card=[card_token]" \
 -d "description=Espago docs"

Here is how the response will look like. It is sent using JSON formatting. Id and state are pivotal. More on back requests

1. Submitting the form

By clicking on the submit button, the client sends a HTML form with hidden fields containing the payment details, through the POST method, to the Espago gateway and gets redirected to the secure web page.

<form accept-charset="UTF-8" action="https://sandbox.espago.com/secure_web_page" id="espago_secure_web_page" method="post">
  <input name="api_version" type="hidden" value="3" />
  <input name="app_id" type="hidden" value="ms_771eUTliRiZ" />
  <input name="kind" type="hidden" value="sale" />
  <input name="session_id" type="hidden" value="1559655843622983577" />
  <input name="amount" type="hidden" value="10.00" />
  <input name="currency" type="hidden" value="PLN" />
  <input name="title" type="hidden" value="payment_id:294" />

  <input name="checksum" type="hidden" value="938ee2f7729ac4ba1a7c98f5ead8b167" />
  <button name="button" type="submit" class="btn espago-blue pulse">Pay</button>
</form>

2. Charging the client

The client fillings the card data form and the payment with 3-D Secure strong authentication is proceeded. When the authorization is completed, a back request is sent to the merchant service with the authorization details.

3. Redirecting to the merchant

Depending upon the payment status, the client gets redirected to one of the two URLs (for the positive or negative authorization result). The merchant service should display the payment status and if the payment is rejected - also a recejt reason..

curl -i https://sandbox.espago.com/api/secure_web_page_register /

-H 'Accept: application/vnd.espago.v3+json' \

1. Calling the iFrame

In the first step the client calls the Espago iFrame clicking on a button (the call has to be made in your script, by the function called: showEspagoFrame()). Next, the client enters his credit card information, which get sent asynchronously to the Espago gateway in order to generate a token.

 <script src="https://js.espago.com/espago-1.2.js"></script>
 <script 
   async=""
   data-id="EspagoFrameScript"
   data-key="VrYVaA1CjmRooKh63YYv"
   data-live="false"
   data-button="Pay"
   src="https://js.espago.com/iframe-1.0.js">
 </script>

 <a id="pay_btn">Zapłać</a>

$('#pay_btn').click( () => {
  showEspagoFrame()
})

2. Receiving tokens

After receiving the token, the Espago script searches for a form with an id of: espago_form, and creates a new input therein: <input type="hidden" id="card_token" name="card_token" value="[TOKEN]">. The form is then submitted to the designated URL.

<form id="espago_form" 
      action="/charge_client" 
      accept-charset="UTF-8" 
      method="post">
</form>

If the token was not used, the CVV code from the token will be automatically removed after a maximum of 2 days from creation, and the entire token after 2 months.

3. Charges

After receiving the token, the Merchant’s server should send a request with the POST method to the following URL: https://sandbox.espago.com/api/charges.

curl -i https://sandbox.espago.com/api/charges \
 -H "Accept: application/vnd.espago.v3+json" \
 -u ms_771eUTliRiZ:SeCreT_P@ssw0rD \    # app_id:pass
 -d "amount=10" \
 -d "currency=pln" \
 -d "card=cc_8a1kqN20X6JYeuD-Y" \    # token

  end

  # @param body [Hash, nil]
  # @param method [Symbol]
  # @return [Net::HTTPResponse]
  def send(path, body: nil, method: :get)
    uri = URI.join('https://sandbox.espago.com', path)
    request = request_class(method).new(uri)
    request.basic_auth(@user, @password)
    request['Accept'] = 'application/vnd.espago.v3+json'
    request['Content-Type'] = 'application/json'
    request.body = body.to_json if body

    Net::HTTP.start(uri.hostname, uri.port, use_ssl: true) do |http|
      http.request(request)
    end

    currency: 'PLN',
    card: 'cc_8a1kqN20X6JYeuD-Y',

$result = curl_exec($ch);
if (curl_errno($ch)) {
    echo 'Error:' . curl_error($ch);
}
curl_close ($ch);

4. The response from Espago

After a successful charge request, Espago returns data about the current payment in JSON formatting. The state parameter is key. executed means that the payment has succeded.
Example of a response from Espago:

{
 "id":"pay_772FThyrtalisvgk",
 "description":"Espago docs",
 "channel":"elavon",
 "amount":"10.00",
 "currency":"pln",
 "state":"executed",
 "client":"cli_772coQy1BaW3F0Zn",
 "created_at":1559649971,
 "card":

  "company":"VI",
  "last4":"4242",
  "year":2020,
  "month":2,

  "created_at":1559649956
 },
 "issuer_response_code":"00",
 "reversable":true,
 "transaction_id":"tr_7728ogw8v"
}

5. Response - information for the client

After completing the payment it is necessery to inform your clients about the status of their transaction, together with the reason of rejection (if that is the case). Error codes are available in the ‘Downloads’ section.

  "currency": "pln",

1. Calling the IFrame

The client calls our IFrame suited for gathering CVVs, enters his code and sends it to Espago

<script src="https://js.espago.com/espago-1.2.js"></script>
 <script 
   async=""
   data-id="EspagoFrameScript"
   data-key="VrYVaA1CjmRooKh63YYv"
   data-live="false"
     data-cvv-only="true"
   data-button="Pay"
   src="https://js.espago.com/iframe-1.0.js">
 </script>

 <a id="pay_btn">Pay</a>

$('#pay_btn').click( () => {
  showEspagoFrame()
})

Receiving the token

After the user filled in the form with his card details, the script sends this data directly to Espago Servers. In case of creating a token, the script (by default) returns it form of an input to a form named `espago_form` (this form has to be present on your site, for the script to work!).

You can change this behaviour in these parameters: data-target or data-success in IFrame.

<form id="espago_form">
  <input type="hidden" id="cvv_token" name="cvv_token" value="cvv_xxxxxx">
</form>

Creating a charge

Creating a charge with an additional parameter: cvv=cvv_token_id.

1. Request with data to perform the transaction

Sending a request to Espago Terminals API with terminal data and transaction information to terminals.espago.com/api/charges.

{
  "amount": 12.00,
  "currency": "EUR",
  "description": "Payment #5656",
  "terminal": "1234567",
  "kind": "mobile"
}

2. Response

After submitting the correct data, Espago Terminals will send payment on terminal, and respond with information about the created payment.

{
  "payment_guid": "tp_4455rgT6Ve",
    "state": "sent"
}

When the terminal is not connected or wrong params are provided, then the error message will be given.

3. Sending payment to the payment terminal

After successful API request the transaction will be sent immediately. At this moment client can pay on device, according to terminal payment instructions.

4. Response with transaction status

Once the transaction is completed, the status of transaction will be displayed on the terminal. Transaction information will be sent to the address provided as a back request.

{
  "payment": {
    "id": "tp_7d7z-noWFPW",
    "description": "Payment #5656",
    "state": "success",
    "amount": "12.00",
    "currency": "EUR"
  }
}
