@mkudev Glad to hear you got it working.
For the record:
1. You should not normally have to supply an IPN endpoint to the CoinPayments platform settings. The default one should work. If it’s working now, don’t change it.
2. The complete howto article for debugging these issues is: https://www.dashed-slug.net/howto-debug-an-incoming-deposit-coinpayments-adapter/
3. If you experience any more issues with the plugins, please open a new thread.
