I would start with the REST Technical Reference Guide on EpicWeb. Mark W. ---

Where is that at in EpicWeb? I did a search and found nothing on these lines. ---

@Mark_Wonsil I found an Implementation guide, but not a technical reference. I am assuming the tech reference would be like this API does/affects this. Correct? ---

[https://epicweb.epicor.com/doc/Docs/Epicor10\_RestImplementation\_102200.pdf](https://epicweb.epicor.com/doc/Docs/Epicor10_RestImplementation_102200.pdf) Yes, this is with the other Tech Reference Guides. Not sure why Implementation in the name other than this is how Epicor implements REST/OData. Mark W. ---

@Mark_Wonsil Is there a guide for 10.1.500? ---
**Author:** ![Mark\_Wonsil](https://www.epiusers.help/user_avatar/www.epiusers.help/mark_wonsil/32/51594_2.png) [@Mark\_Wonsil](https://www.epiusers.help/u/Mark_Wonsil)\ **Post date:** [June 27, 2018, 4:12pm UTC](https://www.epiusers.help/t/web-services-api-documentation/45670/7 "2018-06-27T16:12:26Z")
No. 10.1.500 was a technical preview although fairly complete. The first supported version was 10.1.600. Mark W. ---

So, I would need to upgrade to 10.1.600 in order to use rest then, correct? If so, is there a guide for that or is it the same as 10.2? ---

There’s only one guide but gist is similar. You can still use REST in 10.1.500 but it’s not an officially supported version. ---

Ok, that sounds interesting. I tried doing seomthing liek this in Postman [https://server](https://server) name/ERP101500/2017R/api/v1/Erp.Bo.SalesOrderSvc/SalesOrders?$filter=372984$expand=OrderDtls/OrderRels And getting told the resource could not be found. HTTP 404. That is what makes me wonder that I either have the line wrong, or it is not available in 10.1.500. ---

I recommend starting easy before going into a big hairy example like that. Do you get anything at [https://servername/ERP101500/api/help](https://servername/ERP101500/api/help) ? or [https://servername/ERP101500/api/v1](https://servername/ERP101500/api/v1) The other thing is do not forget the BAQ version of the call. If you create a BAQ with a parameter, you can call the BAQ with parameters and just retrieve the columns you want. It’s more resilient to BO changes too. Mark W. ---

Yeah, I tried the easy one earlier. Got Server Error in ‘/ERP101500’ Application. The Resource cannot be found. ---

So you have some setup work to do first… Check out Bart’s REST Novella thread. Lot’s of info there as most of it was written during 10.1.500. > **[REST Overview Novel](https://www.epiusers.help/t/rest-overview-novel/36260/26)** > > I am thinking it might be just a little more involved that a checkbox in the app server configuration 😕 The following errors occurred while attempting to load the app. No assembly found containing an OwinStartupAttribute.

Well, I got it to work till [http://servername/ERP101500](http://servername/ERP101500), but when I add the /api gives me the error, HTTP Error 404.0 Not Found ---

Yes, I did. Makes sense. To be honest, I am not sure what to look for in the Web.config. ---

Fixed! Got it working. I rebuild the appserver and that fixed it! ---

You have to login into EpicWeb. Do you know your login credentials?
