POST /Service.asmx/Delete HTTP/1.1
Host: localhost
Content-
Type: application/x-www-form-urlencoded
Content-Length: length

customerId=
string
HTTP/1.1 200 OK
1) According to this, your URL should be
B4X:
http://192.168.1.239/Service.asmx/Delete
not
B4X:
http://192.168.1.239/WebServicesula/Service.asmx?op=Delete
2)
Your posted string should be in the format
B4X:
customerId=string
which in your example than should be
B4X:
"customerId=1003"
instead of just
B4X:
"1003"
3) Finally, you need
Content-Type: application/x-www-form-urlencode
which you can do by placing this code
B4X:
Job2.GetRequest.SetContentType("application/x-www-form-urlencoded")
after your
B4X:
Job2.PostString(...)
line.
Note, you need to include the OkHttp library to access the SetContentType method of the GetRequest object.
