You'll need to use the COMAPI with Dotnet C# or VB.

thank you for your reply.

what about REST API?
is it exist?

Nope

As mentioned, we do have a rich set of API's in our ComAPI layer. In the 2016 version with our Web Screens, we have introduced a small set of RESTful API's. This list will be increased to include all of the models that we expose via our Web Screens in our August 2016 release (named as our 2017 release).

I'm brand new to Sage, taking over a product that was written for Timberline. Can i get a pointer to the documentation for the ComAPI documentation?
Thanks.

There is no good documentation. Record macros in Sage 300 to see how it does its thing, that's how we all learned.

Hi John
where can i find RESTful API's for 2017 release ?

we need to integrate with sage 300 with PHP

thanks

For the 2017.1 release, we have wrapped our RESTful API's with OpenAPI or Swagger. Visit our Web SDK Open Source on GitHub at github.com/.../sage300-sdk ('master' branch is the current release 2017.1). In the 'samples' folder you will find some WebApi samples (C# using Postman) and in the 'docs/webapi' folder you will find a word document that references our WebApi Endpoints. the OpenAPI is very useful in seeing how the WebApi's work, the payloads, etc.

I hope this helps!
