PayPal Checkout

-- HikaShop version -- : 4.7.2
-- Joomla version -- : 4

I have enabled the PayPal Checkout Plugin at your urging, and the client set up a PayPal Checkout account. I've generated all our keys. Now, how do I configure this payment system? I looked in the documentation, but there appears to be nothing on PayPal Checkout. Several other older PayPal options but not PayPal Checkout. Over at PayPal, I have a lot of configuration options. For basic setup, I chose Standard mode. Correct? I have a suspicion that few if any other parameters matter. I suspect we configure everything in the Hikashop pluigin. It takes over from PayPal Checkout. Correct? Just put in our keys and go. Correct? If you do in fact have some documentation for this newer plugin, please share it with us?
Thank you,

I appreciate your support.
1. For basic PayPal Checkout setup, I chose Standard mode. Correct?
2. I have a suspicion that few if any other parameters matter. We configure everything in the Hikashop plugin. It takes over from PayPal Checkout. Correct?
3. Just put in our PayPal keys and go. Correct?
4. I can enable sandox mode via the plugin or Paypal. I just need to activate in plugin. No need to do the same thing over at PayPal. Correct?
5. PayPal also lets us generate a test card number so we can debug UX. I can use that in live mode, not just sandbox mode. Correct?
I do look forward to having some documentation, but may have a lot of questions, since there is no documentation as of yet. I like what I see but lack clear direction.
Thanks,

Thank you. This answers most of my preliminary questions. Yet, I still want to be totally clear on this following point:
Need I enable sandbox both in the plugin and over at PayPal? I think not. And I think this will always be the case when I encounter a similar instance. The plugin controls everything and whatever settings I select there cascade to PayPal. Correct?
The plugin looks pretty nifty. I see how I'll be able to add the client's branding and add links like a back-to-site button. It'[s more elegant than the usual offsite checkout system. Looks like a development of a plugin I first used years ago with Authorize. Thjey have siknce changfed everything around.
I look forward to the documentation but it's going to come a week too late, as the client wants to go live next week. Please bear with me as I perhaps ask more questions.
Best,,

Thank you.
Now, some more questions about plugin fields.
"Shipping methods." If I activate them in the component, will they appear here? Or, do I have to add them somehow, perhaps with comma-separated text? What do I have to do to make it work?
"Cancel URL" and "Return URL." I want to use a relative URL here because this is a developmental site. When we go live as the new whitewatermarineinc.com, I want everything to still work. Redirecting to the mainpage of our store would be fine. Here is the system URL: index.php?Itemid=122 Can it be made to work this way? What value do I put in?
Thank you,

Thanks for explaining!
Now, we are all set for final testing. Not yet having access to documentation, could someone walk me through this. Step by step, how can I do some test purchases?
Thank you,
