Javascript SDK - No 'Access-Control-Allow-Origin' header is present on the requested resource 1

Hello,

We have a Clover Development Kit (Clover Flex). We have associated and activated the device with Clover App. When we try to connect with Clover Device, we get this error:Access to XMLHttpRequest at 'https://sandbox.dev.clover.com/v2/merchant/YYYYYYYYY/remote_pay?access_token=xxxxxxxxxxxx' from origin 'https://syncoria-payments.odoo.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Things we have done:
1. Allow Insecure Content in Browser
2. Try with multiple browsers
3. Sandbox Url: 'https://sandbox.dev.clover.com/v2/merchant/YYYYY/remote_pay?access_token=xxxxxxxxx'

I am sharing some screenshots. Can you help us regarding this?

Please don't post access tokens in a public forum, even if this is just sandbox. It is likely your access token is not valid. Please make sure your app has read merchant permissions. If it does then you aren't obtaining it correctly. You should be installing your app on your test merchant and navigating to your app by selecting your app in the merchant dashboard.

Hello David,

Thank you for your reply. I already have read permissions for merchant. I can fetch the devices from the Clover Merchant Account. Please see screenshots below.

For now, I am getting Websocket Connection Error.Screenshot from 2021-08-13 06-23-53.png

I would suggest using one of our examples which can be found in our documentation. Also, please don't display an access token in your app.
