Hi @Anton L

Based on Andrey and Thomlin's explanations and the links they shared above, I would like to seek guidance from you.

Question #1:

On this page https://stripe.com/docs/tax/checkout/tax-ids Stripe says:

You can enable tax ID collection on all payment and subscription mode Sessions

In the BxPaymentProviderStripeV3.php file, Line 585-591, there is the following session:

 $aSession = array_merge([
            'payment_method_types' => ['card'],
            'customer_email' => !empty($aClient['email']) ? $aClient['email'] : '',
            'mode' => $sMode,
            'success_url' => '',
            'cancel_url' => '',
        ], $aParams);

My question is: Is this session for both: 'all payment' and 'subscription' mode or just for all payment mode only and there is another separate session for 'subscription' mode somewhere else? I would like to enable the Customer Tax ID for all the sessions.

Question #2:

What are the correct lines to add?

According to the example used by Stripe:

  -d "tax_id_collection[enabled]"="true" \
  -d "customer_update[name]"="auto" \
  -d "customer_update[address]"="auto" \

or

  'tax_id_collection[enabled]' => 'true',
  'customer_update[name]' => 'auto',
  'customer_update[address]' => 'auto',

The way things are in the BxPaymentProviderStripeV3.php file.

I would also like to collect the Real name or Business' legal name and the Billing address to be display on the invoice and receipt documents.

Thanks in advance for helping.
