The Square Register iOS API mediates communication between iOS apps and Square’s payments processing apps. The API’s provider is the vendor of Square payments processing hardware that include the Square contactless and chip reader. Developers can choose between the Android and iOS versions of the Square Register API, although the Android option provides access to only native apps while the iOS option provides access to both web and native apps. The API that requires OAuth 2.0 authorization transmits requests and responses in HTTP and JSON formats.
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.
