webhook_url = "https://us-central1-xxx-xxxx.cloudfunctions.net/webhook_test/test"

testdata = {"current": {"url": "https://test.com"}, "payload": {"signup": {"method": "home page", "referrer": "https://auth.wehelpcode.com", "destination": "https://test.com"}, "user": {"id": "4465-a4b4-640a81c5bd75", "first_name": "Code", "last_name": "Gray", "email": "test@test.com"}}}
testresponse = request('POST', webhook_url, json=testdata)
print(testresponse.text)
