Is it possible to change orgs via API key and not basic auth?

UPDATE: Seems as though this is not possible and API keys are tied to one specific org.

I read that this is possible using Basic Auth like this:

/api/user/using/:orgid

And I have tried the same endpoint with an API key and I get a 404.

Background Info: I need to pull panels from specific dashboards associated with specific orgs. However, I am only able to do this when a dashboard is associated with the current org. Therefore, I need to switch the current org to the org that has the pertinent dashboard before I query the API for a panel.

Does this help: http://docs.grafana.org/tutorials/api_org_token_howto/

Yes, thank you. I’ve realized that an API key won’t work for the functionality I need. I’ve edited the original post.
