Web Service API Business Central OnPrem

Within an On Prem BC18 Installation I' have exposed a new api page to my web service and I'm attempting to connect via web service.

What settings and url would I need to connect to the following:

page 50120 MyCustomerApi
{
PageType = API;
Caption = 'My Customer API';
APIPublisher = 'contoso';
APIGroup = 'app1';
APIVersion = 'v2.0', 'v1.0';
EntityName = 'customer';
EntitySetName = 'customers';
SourceTable = Customer;
DelayedInsert = true;

layout
{
area(Content)
{
repeater(GroupName)
{
field(id; Rec.systemId)
{
Caption = 'ID';
}
field(name; Rec.Name)
{
Caption = 'Name';
}
}
}
}
}
