A chatbot we created in Google DialogFlow needs to make API calls (GET and POST) to obtain important personal data from a remote server, so the connection needs to be secured with an X.509 certificate.
Right now we are utilizing the DialogFlow Inline editor to make data request calls internally to a Firebase database, but puzzled with changing this set-up to connect to a remote server instead.
Would anyone be so kind to provide any guidance how to implement such a secure integration via an X.509 certificate to make API calls, please?
