Hey @Denish,
Thanks for reaching out to the Retool community!
Would you mind helping me understand where the Stripe processing you are with some screenshots? Any extra details about the issue here would be appreciated. I can help better after that.
What sounds like you are using is the "Stripe Card Form" module which lets you embed payment options into the app and submit that to Stripe. The module and its details can be found on this page here: The Stripe Card Form component for Retool Apps | Retool Docs
I think this Community page may be relevant, as well. Bob walks through this process on how to set it up, test it, and use it for payments. He mentioned "you'll need to enable 'Storage and cookies' for the custom component before it renders" which might be what you are missing here: Credit Card Payment - #6 by bobthebear
Jack walks through a similar process and how this gets configured here: Stripe and payment link
Looking forward to hearing back and getting this resolved together.
Regards,
John | Retool Support
