Our guide defines what is API in accounting and names some top-rated software choices for efficiently streamlining your accounting and global payment and payout processes as accounting integrations.

What is an Accounting API?

An accounting API (application program interface) is software containing a connector that seamlessly integrates accounting software or an ERP system with third-party software solutions to give accounting professionals access to automation and additional functionality for greater efficiency and other software user benefits. 

The software website has API documentation for developers to connect its software. The documentation may be called an API reference. An accounting API lets other software products or websites access the data of Internet users with the OAuth open standard. APIs require user input for data sharing, whereas webhooks share some data upon a certain action with custom callbacks. JSON (JavaScript Object Notation), an open standard, may be used for transmitting data in web applications software. 

An accounting API may be used to connect an accounting software program to financial and payments automation software, accounting spreadsheets like Microsoft Excel or Google Docs, and multiple third-party add-on apps in an online apps store. Although a CRM software system for customer relationship management isn’t designed specifically for accounting, it interacts with some accounting functions in an ERP system through API integration.
