Hello,
Thank you for your inquiry. I found out that there's no formal plan to open up the Preauthorized Payment Cancellation Service (PPCS) API to United Kingdom customers just yet; but in about 12 months time we can expect VEPSS (Visa Europe payment Stop Service) customers in United Kingdom to have transitioned to using Preauthorized Payment Cancellation Service (PPCS)/Visa Resolve Online (VROL).
I think you've submitted an inquiry to developer@visa.com, and I received confirmation today that someone from the Visa Developer team will be directly reaching out to you to discuss this.
Thank you,
Diana
