Getting Started with Shell Card Management APIs

Introduction

The Shell Card Management API provides secure and structured access to the Shell Card Platform, enabling integration with Shell’s internal systems for managing card-related resources.

This REST-based API uses the POST method for all operations—including retrieval, creation, update, and deletion of resources. It supports flexible search capabilities through JSON-encoded request bodies and returns JSON-formatted responses. Standard HTTP status codes are used to indicate the outcome of each request.

Authentication is handled via OAuth 2.0 using the Client Credentials flow. Access tokens must be included in the Authorization header of each request.

All resources are managed within the Shell Card Platform, which abstracts the complexity of backend systems. Some operations may be processed asynchronously, and clients should be prepared to handle delayed responses or polling mechanisms where applicable.

Go to the Shell Developer Portal: https://developer.shell.com

Install the Package

Install the gem from the command line:

gem install card-management-sdk -v 2.0.0

Or add the gem to your Gemfile and run bundle:

gem 'card-management-sdk', '2.0.0'

For additional gem details, see the RubyGems page for the card-management-sdk gem.

Test the SDK

To run the tests, navigate to the root directory of the SDK in your terminal and execute the following command:

rake

Initialize the API Client

Note: Documentation for the client can be found here.

The following parameters are configurable for the API Client:

Parameter	Type	Description
environment	Environment	The API environment. Default: Environment.SIT
connection	Faraday::Connection	The Faraday connection object passed by the SDK user for making requests
adapter	Faraday::Adapter	The Faraday adapter object passed by the SDK user for performing http requests
timeout	Float	The value to use for connection timeout. Default: 60
max_retries	Integer	The number of times to retry an endpoint call if it fails. Default: 0
retry_interval	Float	Pause in seconds between retries. Default: 1
backoff_factor	Float	The amount to multiply each successive retry's interval amount by in order to provide backoff. Default: 2
retry_statuses	Array	A list of HTTP statuses to retry. Default: [408, 413, 429, 500, 502, 503, 504, 521, 522, 524]
retry_methods	Array	A list of HTTP methods to retry. Default: %i[get put]
http_callback	HttpCallBack	The Http CallBack allows defining callables for pre and post API calls.
proxy_settings	ProxySettings	Optional proxy configuration to route HTTP requests through a proxy server.
client_credentials_auth_credentials	ClientCredentialsAuthCredentials	The credential object for OAuth 2 Client Credentials Grant

The API client can be initialized as follows:

require 'shell_card_management_ap_is'
include ShellCardManagementApIs

client = Client.new(
  client_credentials_auth_credentials: ClientCredentialsAuthCredentials.new(
    o_auth_client_id: 'OAuthClientId',
    o_auth_client_secret: 'OAuthClientSecret'
  ),
  environment: Environment::SIT
)
