Optimal Payments offer a range of online, mobile and alternative payment methods using APIs designed to streamline payment integration into applications and websites. The Customer Vault enables developers to store customer information such as credit card numbers and contact information to quickly reference for an expedient shopping and checkout experience. The API can hold multiple payment methods per customer and can be used to create and manager customer profiles, all through a RESTful API using HTTP with JSON formatted requests and responses. Optimal Payments offers a test API endpoint to demo API integrations before publication.
The following is a list of libraries from ProgrammableWeb's Library Directory that matched your search term. Although there many different interpretations of the word "library" among software developers, ProgrammableWeb adheres to a specific definition so as to clearly distinguish libraries from SDKs and frameworks in a way that will facilitate clean search results. In ProgrammableWeb's parlance, the term "library" is strictly used to describe a platform-specific software tool that, when installed, results in the provisioning a specific API. Conversely, SDKs are exclusively for consuming APIs and Frameworks are agnostic to specific APIs. If you think a library, SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
