    "card_type": "visa",
    "cardholder_name": "JOHN DOE",
    "service_code": "123",
    "expiration_month": "12",
    "expiration_year": "2021"
  }

Card operations

To send card to a 3rd party service (e.g. Payment Gateway), you can use the the Send Card method:

Request

POST https://pci.channex.io/api/v1/cards/{card_token}/send?api_key={YOUR_API_KEY}&method={HTTP_METHOD}&url={TARGET_ENDPOINT}

{
  "card": {
    "card_number": "%CARD_NUMBER%",

    "expiration_year": "%EXPIRATION_YYYY%"
  }
}

Send card to Stripe

POST https://pci.channex.io/api/v1/cards/<card_token>/send?api_key=<api_key>&method=post&url=https%3A%2F%2Fapi.stripe.com%2Fv1%2Fpayment_methods

Arguments

Argument	Descriotion
card_token	Credit Card token at Channex
method	HTTP Method to send request to target endpoint. One of: get, post, put, delete, patch, head, options
url	Encoded URL of Target Endpoint, should use https protocol

Query Body is optional and depends to Target Endpoint API. Basically, it should contain structure expected by Target Endpoint. To insert real card data into request you can use Drop Ins.

Method with return response from Target Endpoint.

Authorize Card

By PCI DSS rules, we should remove Service Code immediately after the card is Authorized. Some operations at our API call this action automatically. But, because you can catch some problems with Send Card method (3rd party service provide error response), we do not remove Service Code automatically after using the Send Card Method. If your application successfully sent the card info to the 3rd party service, please call Authorize Card method.

Please use this method to remove the service code once you have successfully sent the card to the payment gateway. This is an important part of PCI-DSS.

Request

POST https://pci.channex.io/api/v1/cards/{card_token}/auth?api_key={YOUR_API_KEY}

Success Response

Status: 204 No Content

Remove Card from Storage

If card is not longer required for your business processes, you should remove it from storage by calling this method:

Request

DELETE https://pci.channex.io/api/v1/cards/{card_token}?api_key={YOUR_API_KEY}

Success Response

Status: 204 No Content

Show Card Form

To implement the ability to Show Card at your application you can use method Show Card. This method will return HTML Page with credit card information that you can insert into your application.

GET https://pci.channex.io/api/v1/show_card?card_token={CARD_TOKEN}&session_token={SESSION_TOKEN}&service_code_token={SERVICE_CODE_TOKEN}

Arguments

Argument	Description
card_token	Card token at Channex.PCI
session_token	One-off Session token with scope show_card
service_code_token	One-off Session token with scope show_service_code to show Card Service Code

By default, Channex PCI will return a HTML page where user can see Card Number, Expiration Date, Card Type and Cardholder Name, but Service Code (CVV, CVC) will be hidden. To be able to see Service code, you should provide the service_code_token which will be used to request Service Code.

Service Code will be hidden by a button, by clicking this button the user will load Service Code and it will be immediately removed from Storage.

Our iframe to show card information makes the user click to see the service code (CVV/CVC). This is helpful because once it is viewed it must be deleted.
