May I confirm you followed this process to approve the application? Note - there are different tabs for JWT/CCG apps vs Oauth ones. 

May I have the client id of the application? 

Hi Alex,

Good day,

please find the client ID of the APP: fb2fg9kfxry219fc2yfyhf7lhbp59l3r

On my side - I don't see that the admin has followed the instructions at the link I shared earlier.

Yeah Please find the below APP, After doing all the configurational changes resubmitted the APP for Approval. 

Since a month its "pending for Authorization" and Dropped email to Admin but getting out of office response(box-admin+developer@apple.com).

App name: OGCPortal

Client ID: cd0h41a9t3xs98x6562dzcpvqhs77iin

So - Box doesn't control the custom application approval process. That is done in the individual instance's admin console. Someone at Apple would - probably your IT org. We have no visibility into the owner of box-admin+developer@apple.com. 

yeah thats the reason I am stuck here, connecting with org members still no luck.

One clarification required:

Once the App gets approved the error which I am getting will be resolved ?

App name: OGCPortal

Client ID: cd0h41a9t3xs98x6562dzcpvqhs77iin

(The API returned an error code [400] unauthorized_client - This app is not authorized by the enterprise admin)

Correct. The error will no longer be there. Unfortunately, Box doesn't have a way to get you in contact with your own organization's IT department. Let us know if you get another error after the app is authorized. 

Yeah Sure, I will let you once I progress. Thank you :)
