Hi @rjctukan,
Greetings. Hope you are doing well. Really sorry for the inconvenience.
Regarding your query, I am really sorry but it would be great if you could please explain a bit more about the recopy API key issue, actually where you are recopying the API key. It would help me to assist you further.
In our BetterPayment settings, we have global settings for payment methods with API keys. Once you set up the API keys from the WordPress Dashboard -> BetterPayment -> Settings -> Payment it will automatically work for all the BetterPayment widgets. For reference please check this screencast – https://d.pr/v/fZWtEx
Again, I am really sorry for the inconvenience. You can also share a screencast of the issue so that I can check and help you out.
Please feel free to reach out anytime you have issues or queries. We are always here to assist you.
Thanks and Regards.
