question

There's a "Use Steam Payments sandbox endpoint for test transactions" option on the Steam add-on page. Can you make sure that's enabled?

Also, can you share the full flow? How are you calling StartPurchase and PayForPurchase, and can you confirm that the Order ID you're using in ConfirmPurchase is the one you got from that flow?

Finally, you're saying you get "Invalid input parameters" from the Steam callback, which would imply you're getting it from Steam in the MicroTxnAuthorizationResponse_t. Can you also confirm where that's showing up in your flow, if you meant something else?

Yes, the "Use Steam Payments sandbox endpoint for test transactions" option is enabled.

The error comes from the "ConfirmPurchase" function. It enters the error function and it gives me the error message "Invalid input parameters"

Here's my full code:

protected Callback<MicroTxnAuthorizationResponse_t> m_MicroTxnAuthorizationResponse;
public Text text;
	
public string GetSteamAuthTicket()
{
	byte[] ticketBlob = new byte[1024];
	uint ticketSize;


	HAuthTicket hTicket = SteamUser.GetAuthSessionTicket(ticketBlob, ticketBlob.Length, out ticketSize);
		
	Array.Resize(ref ticketBlob, (int)ticketSize);
		
	StringBuilder sb = new StringBuilder();
	foreach (byte b in ticketBlob)
	{
		sb.AppendFormat("{0:x2}", b);
	}
	return sb.ToString();
}

{
	if (SteamManager.Initialized)
	{
		m_MicroTxnAuthorizationResponse = Callback<MicroTxnAuthorizationResponse_t>.Create(OnMicroTxnAuthorizationResponse);


		PlayFabClientAPI.LoginWithSteam(new LoginWithSteamRequest

			CreateAccount = true,

	}
}

	if (pCallback.m_bAuthorized == 1)
	{
		text.text += "\nAuthorized Payment";


		Debug.Log("Authorized Payment");


		ConfirmPurchase(pCallback.m_ulOrderID.ToString());
	}
	else
	{

	}

	});
