When you are processing a Batch Entries or Import Files you might get error message as below
This is because stripe has recently made some changes to their API wherein you have to enable the below setting when you send credit card numbers to their API.
Note: The below changes are only required for Batch Entries or Import Files, normal checkout form uses the updated API and will not require any changes. Stripe allowed users that registered before 2017 to continue using the API without throwing this security issue. Only newly registered users get this warning so they may be able conceive the payment differently using the new token mechanism released in April 2019
Solution:
You need to log a case with them to get it enabled from the backend. Please refer to the following link for how to log a case with Stripe and also what is required as a supporting document: https://support.stripe.com/questions/enabling-access-to-raw-card-data-apis
