Hi, let me help you with this.
payment id does not get reattached again
What do you mean by this?
soft ermine
I mean that I would like to make so that the customer cannot add a new "payment method" if they use the same credit card or other payment methods. for example when I check the customer that I created and I make a new subscription it will add the same card again in the payment method section
and a new payment method id is being created every time I use the same card in test mode

By the "same card" you mean the same card number, right?
soft ermine
Yes for example the visa test card number

It's normal to have multiple different PaymentMethod objects for cards with the same number. You can check if they have the same fingerprint: https://docs.stripe.com/api/payment_methods/object#payment_method_object-card-fingerprint
If you want to avoid this, present the saved PaymentMethods to the customer before allowing them to add a new one. Maybe limit the number of saved PaymentMethods, i.e. "if you want to add a new card, delete one of the old ones".
Payment Element supports displaying saved cards: https://docs.stripe.com/payments/existing-customers?platform=web&ui=elements

Ok thanks you so much, that helps a lot! I will have a look at that 😁
