The Stripe block allows you to collect payment. You first need to add your Stripe:

​
Connect Stripe account

After clicking on Select an account > Connect new, a configuration popup appears:
Stripe configuration
Test keys will be used in the preview for testing purposes. Live keys will be used in the published bot. If you’d still like to still use the test keys in the published bot you just need to also fill in the test keys into the live keys inputs. If you would like to simulate a successful payment, use test cards from the following list in Stripe -> https://docs.stripe.com/testing?testing-method=card-numbers#cards

​
Input configuration

Once you have a Stripe account, you can select it and configure your input:
