How do I retrieve a user's profile picture via Zoho OAuth 2.0 API?

I've been trying to retreive the users profile picture through Zoho OAuth 2.0, testing it with Postman. This API uses authentication through tokens.

First I'm authenticating through:
https://accounts.zoho.com/oauth/v2/auth

and getting the token with:

https://accounts.zoho.com/oauth/v2/token

I used these scopes while testing:

• ZohoCliq.Profile.READ

• ZohoCliq.users.READ

• zohocontacts.contactapi.READ

Endpoints I’ve tried (all return either the default placeholder image or blank):

• https://contacts.zoho.com/file?t=user&ID=\\<zuid>

• https://contacts.zoho.com/file?fs=thumb&ID=\\<zuid>

• https://profile.zoho.com/file?t=user&ID=\\<zuid>

• https://profile.zoho.com/file?fs=thumb&ID=\\<zuid>

• https://accounts.zoho.com/oauth/v2/int/file?zuid=\\<zuid>

Issue:
Every request returns either the default placeholder image or a blank response, even when I’m certain the user has a profile picture set.

Question:
Is there a different endpoint, scope, or parameter required to retrieve the actual profile picture for a user?

Here's what I tried and it worked.

• Authorize the user with profile scope. View Docs →

• Make request to https://accounts.zoho.com/oauth/v2/userinfo with the credentials (access token).

• In the response, there will be photo field, which has the signed-url for the image. You can use it in <img> tags or download it.
