H5 Scripting - IonApiService is not defined

Hello,

I am new to H5 Scripting and I'm working on an on-premise M3 environment. When I try to call IonApiService on cloud environment it does not give me any error but on premise it show me a "IonApiService is not defined at <my function>". Does anyone have an idea why?

Code I'm trying to run:

let baseUrl = IonApiService.Current.getBaseUrl();

Thanks.

There is no support for IonApiService in on-premise M3. That is why this fails. The reason is that the version of the Infor Grid that the on-premise M3 is using has a version that is too old and it's not possible to get a token to authenticate against the IonAPIService. If you want to call IDM there is a proxy application that you can install and use to access IDM with a relative path.

Thank you for the quick reply.

Is there any documentation that I can follow to implement this workaround?

My usecase will be to call APIs that are available in ION API mostly as IDM and M3 apis.

Which API You need in IONAPI?

IDM APIs such as Add an Item or Count (/items , ?/items?/count) and for M3 apis related to Invoice.

Thanks.

This is the KB article for the IDM Proxy. https://support.infor.com/espublic/EN/AnswerLinkDotNet/SoHo/Solutions/SoHoViewSolution.aspx?SolutionID=1929652

If you are calling IDM and M3 from a H5 Script you don't have to use ION API, and on premise you cannot, you can call the services with a relative path since your script (both for IDM, with proxy, and for M3) is calling against the same server as M3 / H5 was loaded from.

As for the documenation for IDM APIs and M3 APIs I don't have any links. I suggest that you check the documentation or ask a new questions specifically regarding those APIs. If this was for cloud I would tell you to check the swagger documenation in ION API. You can potentially still do that, as long as you remeber to not call the APIs through ION API, but have your code go directly to the host where you have IDM and M3. If you use the developer tools in the browser you will see that the H5 client and the IDM client calls to these endpoints directly. Just one reminder to have a relate path, something like "/the-root/" and not a full URL with the hostname.
