Hi,
I have a web based application for which I would like to include the clover iframe checkout process into my cart. This is for this ONE client only, and it is thus a private app. I am not using any webhooks. How can I go about getting it working?
I have been working in the sandbox environment, and I was using the private key token successfully, until recently it is no longer working - authentication fail. I believe it is changing. I am trying to set up the oAUTH if I need, or can I work around this as this is a private app?
