Does Microsoft Search API(/search/query) work only with delegated access token?

Question

Hi,

I'm facing issues while using Microsoft Search API(https://learn.microsoft.com/en-us/answers/questions/872976/microsoft-search-api-errors-out-with-value-cannot.html).
It is working on Graph Explorer where the token is delegated one.
So, I would like to confirm if Search API only works with delegated access token or it can work with app-only tokens("grant_type":"client_credentials") as well?

Hi @captain_atharv

Yes, search query currently only support delegated permissions, this endpoint is not yet available for application context. You can follow the graph changelog for any updates to this endpoint.
