UpdatePaymentMethod: unable to delete properties

I’m unable to delete properties at all when trying to update a PaymentMethod. I’ve all 4 of the following approaches. I will use the address.city as an example:

• PaymentMethodUpdateParams.BillingDetails.Address.builder().setCity(null)
• PaymentMethodUpdateParams.BillingDetails.Address.builder().setCity(“”)
• PaymentMethodUpdateParams.BillingDetails.Address.builder().putExtraParam(“postal_code”, null)
• PaymentMethodUpdateParams.BillingDetails.Address.builder().putExtraParam(“postal_code”, “”

I’ve also tried mixing-and-matching these 4 cases, but nothing works.

I get this error when it’s empty string: com.stripe.exception.InvalidRequestException: You cannot set 'billing_details[address][line2]' to an empty string. We interpret empty strings as null in requests. You may set 'billing_details[address][line2]' to null to delete the property.

It seems to be roughly the same issue as: https://github.com/stripe/stripe-java/issues/788.

I would reckon that the PaymentMethod.update is almost completely useless without the ability to delete values.

@decoursin You are correct, this is a bug in the library. There should be a setFooter(EmptyParam value) override, but it doesn’t exist currently. We’ll look into it and release a fix.

Hi @decoursin. Fields that can be unset have an overload method that accepts an EmptyParam value, e.g.: https://github.com/stripe/stripe-java/blob/4a7a241288cc626a6ef0142a1c3ec79ba5174857/src/main/java/com/stripe/param/CustomerUpdateParams.java#L255

The only valid EmptyParam value is EmptyParam.EMPTY. So for instance this is how you’d unset the address field on a customer:

Customer customer = Customer.retrieve("cus_123");
CustomerUpdateParams params = CustomerUpdateParams.builder()
  .setAddress(EmptyParam.EMPTY)
  .build();
Customer updatedCustomer = customer.update(params);

In the case of PaymentMethodUpdateParams, none of fields in billing_details[address] nor the parent field billing_details[address] itself are unsettable in the API, so the Java library does not provide overload methods to pass EmptyParam.EMPTY for any of these fields.

I will raise this issue internally, but I also recommend you reach out to support at https://support.stripe.com/email to request this feature and give some details about your use case.
