There isn't a Checkout Session setting for this. You would need custom code to store this info per customer and then check it before creating Checkout Sessions for them. You can probably store whether they have used a trial either in your own database or on the metadata for the customer object

but I have no idea about the payment methods, what if a customer creates 2 accounts in my database? then he would get 2 trials

Cards have a fingerprint attribute that will always be the same for the same card on your account. You can use that to detect previously saved versions of the same card https://stripe.com/docs/api/payment_methods/object#payment_method_object-card-fingerprint
Are there other payment methods that you are using? Can check in to how to check for those
mild jewel
then I would need to first ask for payment method with something other than a checkout session?

It looks like there is also a fingerprint property for a lot of these payment methods:
https://stripe.com/docs/api/payment_methods/object#payment_method_object-us_bank_account-fingerprint
https://stripe.com/docs/api/payment_methods/object#payment_method_object-au_becs_debit-fingerprint
It looks like there isn't a way to list payment method by fingerprint so I think at the moment you will need to store the fingerprints and compare them later.

because I cannot have a custom duration trial with a coupon right? I could only do 1 period free
mossy elk
You can set a custom duration_in_months if that is helpful https://stripe.com/docs/api/coupons/create#create_coupon-duration_in_months
Also I am realizing a hurdle here in that you won't know the PM information until the user submits their payment details in the Checkout Session. Maybe you can do the check after the details are submitted and if you detect details that you have already seen you can pause the subscription and notify the user that they can resume without a trial
mild jewel
yeah but that is pretty bad for user experience. So what is the standard way of offering trials which are "first time only" in stripe? I assume that a lot of people use this

Hello 👋
As far as I know, there's no way to prevent this without writing the code that prevents customers from creating duplicate subscriptions.
I believe we've received similar feedback in the past and the team is working on something that'd allows merchants to control this but it isn't something that we support today out of the box.
