Processing Free Transactions

Good day @snesson

Yes, you will need to change needs_payment function. In WooCommerce, the transactions with $0 will NOT be allowed and to overcome with that we did the manual change in that function.

In settings if you enable the pre-auth, it will allow user to enter credit card information with $0 transaction.

Hope that answers your question. Let us know if we can be of any further assistance.

Just to confirm - if I check the Allow pre-authorization checkbox, the patron will have to enter credit card information, and the opportunity will be created in Salesforce with $0 and a stage I map to pre-authorized transactions. Do I have to make the manual code change to the needs_payment function in that case as well?

Good day @snesson

Yes, you need to change that in function as well:

To allow for processing free transactions, the following manual change has to be made to the "needs_payment" function in "woocommerce/includes/class-wc-cart.php".
Original code: return apply_filters( 'woocommerce_cart_needs_payment', $this->total > 0, $this );
Modified code: return apply_filters( 'woocommerce_cart_needs_payment', $this->total >= 0, $this );
This code change has to be made after each upgrade of WooCommerce.

Hope that answers your question. Let us know if we can be of any further assistance.

To allow for processing of a free $0 transaction without credit card information in WooCommerce, if I uncheck the Allow Pre-Authorization for $0 balance checkbox in the plug-in, and enable custom payment types in Salesforce C&P Settings, do I also need to make the manual code change to the needs_payment function in the WC plug-in?
