Do I need a domainKey if I'm hosting my own chatkit endpoint?

[azambuilds]

I'm confused here because I have a custom /chatkit endpoint so I don't see why I need to supply a domainKey.

But if I omit the domain key param I get:

index-DXTbcclM.js:217  Uncaught InvalidFrameParamsError: Invalid frame params: ChatKit.create():
✖ Invalid input

Yes, domainKey is required when hosting your own ChatKit backend.

I understand this requirement appears confusing, but this is helps ensure you have a relationship with OpenAI Platform for your integration.

This check is disabled in testing environments, but enforced in all others (e.g., staging/production).
