Hi @klng,
Unfortunately, the Visa Checkout/Click to pay team does not accept direct merchant. You will need to work with a partner in order to integrate Visa Checkout/Click to Pay into your project.
You can find the list of Partners here: Partners to integrate with Visa Checkout: https://globalcheckout.visa.com/visacheckoutPartners
Please note, partners handle integrations on their end and will be able to help you with any technical questions you have, due to the fact that, that they manage a different integration with our API and the Visa Developer Portal.
Thanks,
Illana
