How do you get a software developers kit? Is there a phone number to call or someone to email?
Hi Best Business Strategies,
Thanks for reaching out. Did you ever find an answer to your question? The SDK is a free download, however, to sign up as a development partner or to get support for the Software Development Kit (SDK) there is an enrolment procedure.
To access Sage 50 US's SDK visit the knowledgebase article titled Sage 50—U.S. Edition: SDK Download Portal. In order to access this article, note that you will need to log into the Customer Portal / Sage KB with a Sage ID login tied to an account that has a Sage 50 US license.
To sign up for the Sage SDK program, visit

Information on the APIs available for our other product lines which are completely cloud based, can be found here.
Hope this helps!
Warm Regards,
Erzsi
