Question

I need help with MS Graph API for SharePoint. I am getting an error during retrieving the Authentication token when the password has special characters. I am passing the details in the body as parameters. I tried HTML encoding and URL encoding but they both fail, probably because the controller at Microsoft end isn't configured to decode.

Hi @Prasanna Chaturvedi ,

What are the specifics of the reported error? In order to better help you solve the problem, if it is convenient, you can describe your problem in more detail, such as the error content and your operation steps or screenshots.

You can try using the Microsoft Authentication Library (MSAL) for access token acquisition. Additionally, make sure that the access token is valid and that you have requested the correct set of permissions based on the Microsoft Graph APIs your app calls.
