For example, you can just use HCubature.jl with a change of variables to map the domain to a box. For example, see: [2D integration over non-rectangular domain using cubature - #7 by stevengj](https://discourse.julialang.org/t/2d-integration-over-non-rectangular-domain-using-cubature/2991/7)

(You could also do nested calls to a 1d quadrature routine like `quadgk`, though this requires some care for the tolerance of the inner integrals.)
