Cannot use the CustomFunction API to call a CloudScript(Function), returns "This API method does not allow anonymous callers"

I am using an API

https://{ {TitleId}}.playfabapi.com/cloudscript/ExecuteFunction

to execute a CloudScript(Function) from Unity to Playfab, this playfab function is connected to an URL of an AzureFunction(has anonymous access). On Paper this should work, but when I do through PlayFab SDK using the

PlayFabCloudScriptAPI.ExecuteFunction

it works, otherwise, this does not work, I would like to know why for my own edification.

And yes I use an anonymous login to authenticate the session API and that too with a REST API

https://{ {TitleId}}.playfabapi.com/client/LoginWithCustomID

Server-Side Cloud Script - Execute Function - REST API (PlayFab CloudScript) | Microsoft Learn requires an Entity Token, when you use PlayFab SDK, SDK will manage the Entity Token automatically. If you want to use REST API, you need to set the X-EntityToken header manually. You can obtain the Entity Token in the response of Authentication - Login With Custom ID - REST API (PlayFab Client) | Microsoft Learn.

Yea I did that and used the entity token received from the Anonymous login, that is why it tells me This API method does not allow anonymous callers.

This error "This API method does not allow anonymous callers" means you don't set the EntityToken. The entity token obtained from anonymous login methods like Authentication - Login With Custom ID - REST API (PlayFab Client) | Microsoft Learn can be used to call Server-Side Cloud Script - Execute Function - REST API (PlayFab CloudScript) | Microsoft Learn. You can do some tests with Postman (REST) SDK - PlayFab | Microsoft Learn to get familiar with the process.

Thank you for the support, you are right I have replacedthe Entity Token with the Session Token, they seem to be two different things :))
