Export (express mode) azure function api to Flow, missing security scheme

I try to follow this tutorial where you can create an Azure Function, define it as an api. And then export the api to Flow in express mode. At this last step I see in the tutorial you need to select the security scheme "API Key". But in my situation I do not see "API Key" in the dropdown.

Why I dont see the security scheme "API Key"?

When I export the azure function api manual I can see the security scheme "API Key". Here's a tutorial of how you can export it manual:

Hi @khalidinio,


I have made a test on my side and don't have the issue that you mentioned. 


Please check if you have obtained the API key for your custom API. If you have obtained the API key on your side, please consider refresh your browser or clear the cache of your browser and check if he issue is solved.

We are facing the same issue.

Unable to select APIKey for security, I only see "None".


Please let me know how you resolve this?


Thank you.

I used the manual export of the azure function. That will generate an json file. You can import that json file as a custom connector in flow.

I have the same issue... I feel doing a manual export is not exactly a solution to this problem.


I would like to see a "real" solution making the API Key option available in the dropdown.
