How to dynamically choose payment gateway?

Hi @tonygao,

Thank you for using Paid Memberships Pro.

We do not have this functionality in PMPro, this would require custom development & may be possible using the ‘pmpro_checkout_before_processing’ action, please see: https://www.paidmembershipspro.com/hook/pmpro_checkout_before_processing/

You can also browse the full database of action and filter hooks?available in PMPro here. If you would like to pursue this further, I recommend reaching out to a local WordPress Developer on https://jobs.wordpress.net for further assistance.

Kind Regards.

Thank you very much.
