We don’t currently have tools to automatically build bulk action endpoints (although I’d very much like to do this).

So for this you’d need to define a generic action

defmodule YourCustomMapTypeOfFields do
  use Ash.Type.NewType, subtype_of: :map, constraints: [
    fields: [
     field1: [type: :integer, ...]
     ....
    ]
  ]
end

action :bulk_create, {:array, __MODULE__} do
  argument :inputs, {:array, YourCustomMapTypeOfFields}, allow_nil?: false

  run fn input, _ ->
    # use Ash.bulk_create with `input.arguments.inputs` 
  end
end

Then you can use route/3 to make a generic action route:

route :post, "/path/to/your/route", :bulk_create
