My development endpoint is a sub-domain of a domain that has a wildcard certificate from a certificate authority. the signature i am getting is "cezVeGIQZ2acr6cmNOC/SoytfBxk35aZluOMAHFImvD2A3EUdXgN/98zxAnbySet6bWLLRY7nb4gSeM8tERBOPSFhlU8q6pN40hHnYP6ELxk2mpCUeyXJmOIGCaVxAVZBohrr7XM/xgrMmWLDZNVTWmSYw0Tkrg0U7EpS/SpkqiulffVpiZE4fO9btpY1D7zBjBYuu/6GYQElc63OcCTuFH1smXK0jCldWdk1SvZ04uyLitxLcpzpRpjZ5Tii34pP1NtMnJLakf9BX26Ko98N4Q8m1j8H06 uaDiDbKNYt48ZX5jnfPh4pO1KyKVaLT0t45ocPQq91pKR9GSxdjAsQ==";
