Call IMS Apis from M3 H5 SDK

Hi all guys!

I'm trying to call an IMS API from M3 H5 SDK but I can't figure out what I can put tu X-ClientID Field.

The API is, for example:

/IONSERVICES/api/ion/messaging/service/v3/{logicalId}/acceptedDocuments

I can call It without problem from Postman ( I've added an authorized app in ION API), but both from "ION API" Try it out function and from M3 H5 SDK I can't call it.
Everything I do, I get

{
  "status": "FAIL",
  "code": 464,
  "errors": "Invalid OAuth keypair for logicalId lid://infor.ims.h5sdk_ims"
}

from ION API, and 

status: "FAIL
code: 471
errors: "Invalid client id provided"

From H5 SDK app, executed in chrome. The authorization token in this case is managed automatically by the SDK, using the same authentication of M3.

I tried with my authorized apps client Id but it doesn't work.

I am in a multi tenant environment.

How Can I solve it ?

Thanks a lot, and have a good night!

Hi, did you manage to find a solution to this? I'm also testing IMS through ION API and the the status FAIL code 471.

It is likely that there is a mismatch in the credentials of the Authorized app and the client id you specified in the ION Connection point; Or a wrong OAuth grant type is chosen perhaps? Please refer: https://youtu.be/RJCEsnzSdIM for more info on how to call an ION API in general. For IMS through ION API, your authorized app must be of the type 'Backend Service'.

I was running my tests through ION API and it actually says like this in the swagger documentation:

I tried through Postman and then it worked, so it just seems you cannot run it through ION API swagger documentation.

That is correct. The ION API swagger page uses the SAML bearer grant of the user who is already logged into the portal; It will not work for APIs that require a client ID (such as IMS APIs).
