Entra ID External - Custom Claims Provider help

Hi,

I'm working with Entra ID External identities, trying to get a 'Token Issuance Start' event in a Custom Claims Provider working correctly. I've got all the pieces in place (SPA, web api with endpoint set and configured, app registrations, basic login working successfully, etc). I just can't get the claims provider to call my claims endpoint. Tried so many different ways, get all different errors, all kinds of hours with and without ChatGPT, and still not working. I'm to the point where I'm ready to pay a consultant to help me get past this. But I'm just a solo dev working on a personal side project, I can't call an enterprise consulting company asking for an hour or two on a Zoom call, they don't deal with such miniscule jobs, at least none that I've called. I'm well past the point of making a stack overflow post or something like that, I need a one-on-one with someone familiar with Entra ID custom claims providers for External identities. But I'm guessing most folks with that knowledge are working for some big consulting firm that won't give me the time of day.

Can anyone suggest a small company that could help me, or maybe a place to post online for someone that might want to make a few bucks moonlighting on the side? I'm not looking for a handout, I'll pay a reasonable rate, I just can't afford (and pretty sure I won't need) more than a couple hours. If anyone knows of some site (or anyone interested yourself) please let me know, I'd be forever grateful, I'm at my wits end :)

Thanks,

Andy
