Basic Authentication is a method for an HTTP user agent (e.g., a web browser) to provide a username and password when making a request.
When employing Basic Authentication, users include an encoded string in the Authorization header of each request they make. The string is used by the request’s recipient to verify users’ identity and rights to access a resource.
The Authorization header follows this format:
Authorization: Basic <credentials>
We then construct the
credentials like this:
So if your username and password are
ahoy!, the combination is
twilio:ahoy!, and when base64 encoded, this becomes
dHdpbGlvOmFob3kh. So requests made by this user would be sent with the following header:
Authorization: Basic dHdpbGlvOmFob3kh
When your server or Twilio Function receives this request, it can access the Authorization header, decode the credentials, and look up the user to determine if they should be allowed access to the requested resource.
