405 error updating password with API

[Kelvoshbogobog]

Hi,

I copied the update an existing password powershell from the API manual, put in the API and url fields, have checked and double checked that the API key is the one that has permission over the password...

 

I get a 405 error every time I try to run the script:

Invoke-Restmethod : The page you are looking for cannot be displayed because an invalid method (HTTP verb) is being used.

 

Can anyone point me in the right direction please?

 

Thanks
