How To add paypal subscription in my django rest_framework websites

Question

I'm devlopping a website by django rest_framework and react and I want to use the subscription so that the user manager should pay for example 20 dollars per month ,my project contains two types of users the Resident and Manager ,every Resident user should belong to a village or Dwar as I created , the village is created by a Manager so those residents users has the Manager as responsible for them and if the manager didn't pay no user can log in

    territorial=models.CharField(max_length=80)

    is_real=models.BooleanField(default=False)
    is_resident=models.BooleanField(default=False)
    is_manager=models.BooleanField(default=False)
    

    def __str__(self) :
        return self.username
    def fullname(self):
        return f'{self.first_name} {self.last_name}'


class Manager(models.Model):
    user=models.OneToOneField(CustomUser,on_delete=models.CASCADE,related_name='manager')
    village_name=models.CharField(max_length=60)
    manimg=models.ImageField(blank=True,null=True)
