We have a need to go through an API layer to an Azure AI Services (OpenAI ChatGPT) endpoint and cannot use direct key authentication. We have to use OAuth2 to get a token. However, the only web credential available for a Generative AI Service is HTTP Header and there is no option under Web Credentials for a custom authentication procedure. Also, since these are done at the Workspace level, we do not have access to string substitution for Application Items, Processes, and Computations. Has anyone had this problem or a similar issue? Does anyone know how we might work around this? And is there any plan to allow more Web Credentials to be use for Generative AI Services and have Workspace Items, Processes, and Computations?
