This gem covers most of the Merchant and eCommerce API functionality provided by AltaPay, formerly Pensio (https://altapay.com).

Ruby 2.7.x or later is required.

First, register your Pensio credentials. For example, if you're using rails, create config/initializers/pensio.rb with the following contents:

PensioAPI::Credentials.base_uri = 'Your pensio gateway URI'
PensioAPI::Credentials.username = 'Your pensio username'
PensioAPI::Credentials.password = 'Your pensio password'

This is sufficient in the simple case where you only have a single integration with Pensio, using a single set of credentials.

If you require support for multiple connections to Pensio's API, using different sets of credentials, you must define named 'credentials sets' - see below under Multiple Credentials Sets.

To query transactions in your Pensio gateway, use the method PensioAPI::Transaction.find. This takes a number of parameters as defined in the Pensio documentation. For example:

PensioAPI::Transaction.find(transaction_id: '123')

This returns an enumerable PensioAPI::Responses::Transaction object as many PensioAPI::Transaction objects as match your criteria.

With a transaction object, you can perform several actions.

• Determine status via .status, .captured? and .reserved
• Refund via .refund
• Expose terminal details via .terminal
• Expose billing address via .billing_address
• Map to a subscription object via .to_subscription
• Map to a reservation object via .to_reservation

The funding list functionality of the Pensio Merchant API is exposed via PensioAPI::FundingList.all which returns an iterable collection of PensioAPI::FundingList objects. Calling .download on any of these objects downloads and parses the CSV file from the Pensio Gateway.

To query terminals, use the method PensioAPI::Terminal.all. This will return an enumerable object containing as many PensioAPI::Terminals as are associated with your gateway.

To create a reservation (via the API call '/merchant/API/reservation') use the class method PensioAPI::Reservation.create.

To capture an existing reservation, use .capture. Likewise to release it, use .release.

To create a subscription, use the class method PensioAPI::Subscription.setup. This takes the arguments documented in Pensio's documentation for the '/merchant/API/setupSubscription' API call.

With an existing subscription, use .reserve_charge to place a charge reservation upon the subscription or .charge to attempt a reservation and charge of the associated transaction.

PensioAPI::Ecommerce is a module which exposes the eCommerce API endpoints. Two module methods .create_payment_request and .create_multi_payment_request can be used to generate payment URLs for a multitude of payment types. Consult the Pensio eCommerce API documentation for parameter details.

PensioAPI::Callback provides two methods .parse_success and .parse_failure. These are designed to parse the callbacks Pensio send to your transaction success and transaction failure endpoints. Each returns a callback response which exposes the transaction details for processing by your app.

The library provides two generic error classes for requests.

• PensioAPI::Errors::BadRequest is raised when the response from Pensio indicates that a request has invalid parameters
• PensioAPI::Errors::GatewayError is raised when the parameters have been provided correctly, but the gateway was unable to process the request

Additionally, a third error class PensioAPI::NoCredentials is raised if credentials have not been provided. See "Getting Started" for more details.

If you require multiple connections to Pensio's API using different credentials, you must set up named credentials sets. For example, if you need separate credentials for your membership payments and ticket sales, you can configure them as follows:

PensioAPI::Credentials.for(:membership).base_uri = 'Your pensio gateway URI for memberships'
PensioAPI::Credentials.for(:membership).username = 'Your pensio username for memberships'
PensioAPI::Credentials.for(:membership).password = 'Your pensio password for memberships'

PensioAPI::Credentials.for(:tickets).base_uri = 'Your pensio gateway URI for tickets'
PensioAPI::Credentials.for(:tickets).username = 'Your pensio username for tickets'
PensioAPI::Credentials.for(:tickets).password = 'Your pensio password for tickets'

In this case, you must also pass the credential set to each request, by including a 'credentials' key in the options hash. The value should be a String or Symbol with the credential set name (e.g. :tickets, 'tickets'), or the PensioAPI::Credentials instance itself (e.g. PensioAPI::Credentials.for(:tickets)). For example, these three examples are equivalent:

PensioAPI::Transaction.find(credentials: :tickets, transaction_id: '123')
PensioAPI::Transaction.find(credentials: 'tickets', transaction_id: '123')
PensioAPI::Transaction.find(credentials: PensioAPI::Credentials.for(:tickets), transaction_id: '123')

Typically if you have multiple credentials sets, the default credentials (i.e. PensioAPI::Credentials.base_uri etc) are ignored, and making any Pensio API requests without explicitly passing a 'credentials' argument will raise PensioAPI::NoCredentials. However, if you have an existing Pensio integration using the simple default credentials approach and now want to also use a named credentials set, you can tell the library to explicitly allow this, by setting:

PensioAPI::Credentials.allow_defaults = true

In this scenario, requests performed without an explicit credentials set will use the default set, and those with named credentials will use those. BE CAREFUL: If you accidentally omit the 'credentials' options key when making a request, it will use the default credentials set, which could lead to undesired behaviour. This is why, by default, if you have multiple credentials sets, the default set is disabled.

• Better documentation - more examples, RDoc docs
• Further API implementation
