Dear

I have problem with this message when I used Postman for creating session with login

{"status_code":7,"status_message":"Invalid API key: You must be granted a valid key.","success":false}

i got succed when i generate request token

{ "success": true, "expires_at": "2023-04-08 11:09:11 UTC", "request_token": "123123123123" }

but when i created session with login i was failed

I inputed my username and password correctly with request token, but never succeed.

{ "username": "xxxxxxxxxxxxx*", "password": "wwwwww*", "request_token": "123123123123123123" }

please give me solution for this

It's not a good idea to post your password and TOKEN for all users to see.
I'll change it so other users don't see it.
As your question seems to be a TOKEN usage problem in Postman I will add it in the title.
Maybe other users who use it can help.

I've never used Token, so I don't know how this feature operates.
I can give you the following initial information.

TOKEN - Initial Information
In your profile you will find your API Read Access Token (v4 auth)
https://www.themoviedb.org/settings/api
And here you find the initial instructions.

And here some pages to test

TOKEN Test
You can use test scripts to see how all of this works.
All of this code is frontend only (inspect the source), so it's easy to see what's happening.
Start with v3_auth.html.
