Step-by-Step Troubleshooting Guide

Now that we’ve identified the potential causes, let’s follow a structured approach to troubleshoot and resolve the 0x8102006d error:

1. Verify Your SharePoint Tenant and Authentication

   Double-check your SharePoint tenant URL, username, and password. Ensure you’re using the correct authentication method, such as OAuth or NTLM. If you’re using OAuth, verify that your client ID and client secret are correct.

   
https://your-sharepoint-tenant.sharepoint.com/_api/web


2. Obtain a Fresh Access Token

   Use Postman’s built-in token generator or a separate tool like Azure AD Token Generator to obtain a fresh access token. Replace your existing token with the new one.

         curl -X POST \
         https://login.microsoftonline.com/{tenantId}/oauth2/v2.0/token \
         -H 'Content-Type: application/x-www-form-urlencoded' \
         -d 'grant_type=client_credentials&client_id={clientId}&client_secret={clientSecret}&resource=https://graph.microsoft.com/'
       

3. Check SharePoint Configuration and Permissions

   Log in to your SharePoint tenant and verify that the necessary permissions are assigned to your account or service principal. Ensure that the SharePoint features and APIs you’re trying to access are enabled and configured correctly.

   Permission	Description
   Read	Required for reading SharePoint resources
   Write	Required for creating or updating SharePoint resources
   Execute	Required for executing SharePoint APIs

4. Update Postman Settings and Headers

   Review your Postman settings and update the following:

   • Set the `Authorization` header to `Bearer {accessToken}`
   • Set the `Accept` header to `application/json;odata=verbose`
   • Set the `Content-Type` header to `application/json; charset=utf-8`

   
GET https://your-sharepoint-tenant.sharepoint.com/_api/web
Authorization: Bearer {accessToken}
Accept: application/json;odata=verbose
Content-Type: application/json; charset=utf-8


5. Test and Verify the Request

   Send the request again using Postman and verify that the error has been resolved. If you still encounter issues, try using a different API endpoint or a simple request like `/_api/web` to isolate the problem.
