Requirements for Connecting to the PayJunction API

In order to connect and send requests to the PayJunction API, you will need the following: A PayJunction Application Key, An API Login and Password, TLS 1.2 Support*
Development Sandbox

The following information will allow you to process transactions via the PayJunction test account (i.e. sandbox). Additionally, you will be able to login to the test account in order to view all test transactions. All transactions that are processed via the test environment are for testing purposes only and no money will be collected.
Transaction Processing Workflow

Keyed, Swiped and Recharged (Instant) Transactions: these types of transactions work in a traditional, synchronous manner: an HTTP request is sent to the PayJunction API and a success or fail response is immediately returned.
Available Webhooks

Webhooks can be subscribed to via the PayJunction REST API. Webhooks, like all parts of the API, are tied to the PJMID for an account in PayJunction. If a merchant processes through two different PJMIDs your service will have to subscribe to webhook events for both accounts to receive all data.
