Need help with booking apis

Hi i am making a website where i will list rooms of my hotel for booking online. I have also listed the same rooms on booking.com and few more platforms to generate more business. The problem i am facing is i wouldn’t validate or restrict the booking coming from different sources at the same time.

Is there anything i can implement (any Apis) where i can validate it id the same room is available on my website or somewhere on the other platform?
