CORE FUNCTIONS

CentralPay provides a powerful payment processing API, enabling you to process multi-channel transactions at local and/or international levels.

If you have any problems, before do a technical support ticket, you can see in user case in doc-api.

Introduction

CentralPay API is a REST based API that allows a fast and easy integration of the payment forms. The API uses HTTP to transport and return all responses encoded in JSON.

To simplify integration and testing, CentralPay provides a sandbox where you can carry out your tests.

Authorisations are simulated in test mode.

Test and production modes can be active at the same time - each mode having separate set of public keys and two API ENDPOINT.

We ensure that the data created in test mode will never reach your customers nor cost you any money.

API ENDPOINT

The following link is the core link used to test the API: https://test-api.centralpay.net/

Presentation

The purpose of this document is to present the features of the CentralPay REST API.

By using our Tokenization service and Token.js, sensitive data will not be handled on your servers. The service is fully secure and simplifies your obligations to comply with PCI DSS rules.

2 integration methods are available:

Push & Pay and Smart Form: Ready-to-use services with automation and pre-integrated functions .
Custom form: A set of tools that allows you to design your own payment form using our Token.js instructions.

Creation of "Customer" and "Card"

"Customer" and "Card" allow you to perform recurring payments and track multiple transactions associated with a unique customer.

Marketplace & Plateforme features

Advanced features to manage marketplaces
Creation of sub-merchants with attributes management
Access to a back office that allows to perform transactions analysis and export the results

This new architecture of the API allows us to continuously improve the platform's functionalities and offer new features such as:

More information on cardholders (issuing country, type of card, category, etc.)
Directing transactions to specific acquiring accounts
Fraud detection
Management of recurring payments
Managing complex business rules
Automation system with templates and prefifined actions.

Glossary

cardTokenId	A dematerialized token of the credit card valid for 5 minutes.

Customer	A consumer or buyer for which means of payment have been registered
Card	A Payment Card : VISA, Visa Electron, Mastercard, Maestro, American Express, Diners, ...
Contract	A Merchant Contract recognized by the card schemes identifying the transactions perfomed
Wallet	A Wallet storing the monetary value

Service access

The test platform url is: https://test-api.centralpay.net/v2/rest/

This test platform allows you to test all the services explained within this documentation.

CentralPay will provide you with connection logs to execute the existing functions.

Functions

All functions use the « MIME » type: "application/x-www-form-urlencoded".

Functions use the following methods:

HTTP POST method for object creation or update
HTTP GET method for object search

Authentication

CentralPay API uses "HTTP Basic authentication" for authentication. All requests to our API have to be authenticated (provide the username and the password given by the platform) and have to be made over HTTPS.

If you only plan on using Pop-in forms, you only need to use your "API Secret Key".
You can find your Secret Key in your account settings once you log into your account.

Example of curl code

curl -v -X POST 'https://test-api.centralpay.net/v2/rest/cardToken' \
-H 'Origin: https://example.centralpay.net' \
-H 'Content-Type: application/x-www-form-urlencoded' \
-H 'Idempotence-Key: aa9c8f8aff6b9dc349898d0622c3b95f7a89aecf' \
-d 'card[number]=4000000000000002' \
-d 'card[cvc]=123' \
-d 'card[expirationMonth]=12' \
-d 'card[expirationYear]=2022' \
-d 'card[check]=true' \
-d 'merchantPublicKey=d4cd748bb30526f9c9ea7d15d376c88b96743776fc9ba76b24e4da295a136935'

HTTP Request

Always use HTTP-Header for serialization formats (user_agent, ...)

The Content-Type (application/x-www-form-urlencoded or multipart/form-data) must be inquire for all the request in the header.

The use of the « Idempotence-Key » field in the HTTP header request allows to authenticate the request that has been sent.

If the same « Idempotence-Key » value is sent again, the request will be considered as already processed and will not be triggered again.

This check allows the merchant to avoid sending duplicate entries.

Note: The key of « Idempotence-Key » is valid for 24 hours.

This key should be built with a sha1 hash of the request parameters (WITHOUT datetime) concatenation like this for this example :

Idempotence-Key = sha1(card[number] + card[cvc] + card[expirationMonth] + card[expirationYear] + card[check] + merchantPublicKey)

Example of curl code

curl -v -X POST 'https://test-api.centralpay.net/v2/rest/cardToken' \
-H 'Origin: https://example.centralpay.net' \
-H 'Content-Type: application/x-www-form-urlencoded' \
-H 'Idempotence-Key: aa9c8f8aff6b9dc349898d0622c3b95f7a89aecf' \
-d 'card[number]=4000000000000002' \
-d 'card[cvc]=123' \
-d 'card[expirationMonth]=12' \
-d 'card[expirationYear]=2022' \
-d 'card[check]=true' \
-d 'merchantPublicKey=d4cd748bb30526f9c9ea7d15d376c88b96743776fc9ba76b24e4da295a136935'

HTTP Response

In each HTTP Response, the « Request-Id » field is written in the HTTP header.

Note: If you have a specific request to be sent via CentralPay REST API, please provide us with this information.

Test tools

All functions described in the documentation can be executed with a HTML form (See examples provided in the documentation)

In order to test CentralPay services, different tools are available to check the behaviour of the API (example: Firefox Rest Easy plugin).
