@Rira18 Have you entered your payout information on your account? If so, it is all automatic- you don't have to do anything. Airbnb retains the guest payment until 24 hours, sometimes a bit more, after the guest checks in. Then they release the funds to the host- it will be transferred to the payout account you have registered and can take a few days to appear.
I would suggest you read all the information for hosts provided on the Help site on the Airbnb main site. How you get paid is really basic information, so there are probably a lot of other things about how the platform works that you need to be aware of.
