Integrate with Sage 50 Accounts UK using our RESTful Sage 50 API

You’ve landed on this page because you need a Sage 50 API that provides an easy and reliable way to integrate with Sage 50 Accounts desktop software in real time.

One of the most common integration requirements for most businesses is that of integrating the ‘Business System’ whether that’s a Customer Relationship Management (CRM) system, an Order Processing System or an E-Commerce Website, with the company Financial System. The HyperAccounts Sage 50 API makes even the most complex integrations possible.

You may be frustrated that Sage don’t offer a free REST API for their market leading, small business accounting software package, like their competitors do. The good news is that your search is over. Hyperext have the UK’s only fully functioning REST API for Sage 50 Accounts and Sage 50cloud Accounts (same desktop product). You can find out more about Sage 50 Accounts software on the Sage UK website but you won’t find an API for Sage 50 on there. Don’t get confused by their API for Sage Business Cloud Accounting which although freely available will not solve your Sage 50 Accounts integration problem.

You may also be confused about the relevance of the word ‘cloud’ in the Sage 50cloud Accounts product. We believe this was a marketing tactic that Sage used to compete with the growing trend for cloud accounting software. You may have expected Sage 50cloud Accounts would be a fully online version of the popular small business accounting package. And you would be wrong, because Sage 50cloud Accounts is the same desktop software package as Sage 50 Accounts with the addition of a file synchronisation feature called Remote Data Access (formerly Sage Drive) that allows you to connect to your data in real time from diverse geographical locations via the ‘Sage Cloud’.

Why We Built Our Own RESTful API For Sage 50 Accounts

As a business that develops ‘cloud’ software systems primarily using PHP, the Hyperext team are massive fans of web based accounting software. Over the years we’ve had to solve the Sage Integration problem for many customers, so we’ve invested a lot of time and effort in creating our own set of web services for Sage 50 Accounts. This was difficult because the Sage Desktop software model doesn’t lend itself to web API integrations, but we made it work.

Sage Will Not Support Your PHP Integration

Sage will tell you they don’t support PHP which seems incredibly shortsighted given the millions of software systems, web apps, mobile apps and e-commerce systems that are built in PHP. We originally built our API using PHP, and we ran it successfully for a few years but it was not robust enough to handle multiple concurrent transactions, so we had to take the plunge and rebuild it in .Net using C#. This has vastly improved the connection handling performance and Sage are a bit more helpful since we switched to .Net.
