I am wanting to customise WP rentals theme ‘Request Booking’ feature so the process isn’t reliant on the host issuing an invoice on approval. I want to use stripe auth/capture function so the process is automated. Can I do this using hooks? Do WP rentals themes support hooks? We can’t inject directly into the code as we will lose our ability to upgrade the theme which isnt an option for us.
You can use child-theme for the changes/modifications but better to ask the author about the theme features.
You should request the support from developer
