If you’re using stripe to accept apple pay you can try this plugin.
Even if you’re not using Stripe you should find away to host the file from that post.
The simple answer is yes, you can host the file.
Just upload the file to bubble and name is it exactly as required by apple (.well-known/apple-developer-merchantid-domain-association).
You will need a paid bubble account to host files.
You don’t need to create a folder, bubble will handle that for you.
When you upload the file, in the file name box, enter exactly below and it will work:
On Chrome or Edge you should have android pay or respectively Microsoft Pay activated on your account.
On safari you should have a apple pay activated.
Ignore step two for now. Should still work without it.
Just make sure you’ve entered your stripe authorization and shared keys in the plugin settings of bubble
