I have a brand new install of opencart, when I try to add a payment method here - Extensions > Extensions > Choose extension type > Payments > PayPal Checkout Integration > Download
I see the error "Signature hash does not match!"
Can someone please advise what I am doing wrong?

Follow the instructions here on OpenCart's Documentation to setup your Marketplace API: https://docs.opencart.com/en-gb/extension/marketplace/

If after setting up your API user and secret but it's still not working, then you might want to try going to OpenCart Marketplace here: https://www.opencart.com/index.php?rout ... /extension, and purchase/download the extension that you want to install, and install it through the Extension Installer in your OpenCart admin instead.

Thanks for the information
1. I added my store to my Open cart account and obtained my API username and API secret
2. In Extensions > Marketplace I added my API username and API secret in the top right hand button BUT when I click save the error message " Signature hash does not match!"
Can you help me with this?

You could just go to https://www.opencart.com/index.php?rout ... n_id=38358 and download the extension package and don't unzip it. Then, proceed to your OpenCart store's admin dashboard, and go to Extensions » Installer. Click on the "Upload" button at the top-right corner, and upload the ".ocmod.zip" file that you've downloaded earlier on.

OK, thanks for sticking with me on this.
I have downloaded "paypal_commerce_patform_oc_2x_v1.5.0.ocmod.zip" but when I try to upload it to opencart I get the error "File already exists!"

Are you sure that is the correct version for your version of OpenCart?

No! I wrongly assumed that the one at the top of the list with the most recent date would be the latest.
I should have looked at the version number not the date!
paypal.ocmod.zip installed like a dream!
Thanks so much for your help
