    Hello @yelenabuck,

    Generally this error means you are not using the correct API credentials. If you are convinced your credentials are correct then take a look at your endpoint. Sandbox credentials will not be valid in the production environment and live credentials will produce this error in the sandbox

    Thanks!

    Hi @wpgateways, thanks for your reply. I am pretty sure my credentials are correct as I have re done them a few times now, whether I click the Enable/Disable Sandbox button, this does not make a difference and still is coming up with the same error message. I must say I am slightly confused about the live and sandbox options, as I am quite a beginner.

    Thanks.
