I'm stepping over my line of experience as I do regularly...
Trying to build a private app for Mindbody Online (https://developers.mindbodyonline.com/PublicDocumentation/V6#authentication) but the authentication is killing me.
Somebody told me he's also done it with Session Auth, but I'm fouling that up somehow. Pointers would be greatly appreciated, or if someone had time to do a video call for an hour or so, I'd gladly pay for you time.
Thanks!
