Can't add Azure function to flow

[Anonymous]

Good day!

I'v published azure function in Visual Studio 2017. From Internet I know, I must go to Function API definition and push integration button for function creation in ms flow or powerapps. But, what I see, it is the information about: The API definition (Swagger) is not available for application functions in read-only mode.

How to integrate my Azure function with Flow?

I can't do custom user connector. I'v got the error: Internal error.

Hi @Anonymous,

Please make sure your API definition is valid, about creating an OpenAPI definition for a function, please check the following doc:

https://docs.microsoft.com/en-us/azure/azure-functions/functions-openapi-definition

Besides, to call a function from Microsoft Flow, the flowing doc would be helpful:

https://docs.microsoft.com/en-us/azure/azure-functions/functions-flow-scenario

More details about custom connectors in Microsoft Flow, please check it at here:

https://docs.microsoft.com/en-us/flow/developer/register-custom-api

Best regards,

Mabel

Thank you, Mabel!

I have seen this URLs. In my case, the Azure function made in Visual Studio, not in Azure directly. This is why, I can't use instruction from your links. When I go to API definition, I see Information message about read-only function (from VS, all functions are read-only), and have no interface for generate swagger(open api) or other controls for integration.

What about Azure Functions from Visual Studio? My function works, if I fire it URL, but I can't use it in flow or powerapps. I don't know how.

Have you any solution?

Hi @Anonymous and @v-yamao-msft,

I have the exact same issue - I can't export the API definitions to Flow if the function app is created through Visual Studio, because the function is in read-only mode by default. @v-yamao-msft your links are great, but the top one does only work for function apps created in Azure, not in VS. Do you (or anyone else) have a way to export the API definitions for function apps in read-only mode?

Best,
Emilie

Same here, but I know that it worked a couple of weeks ago

I have an bypass way for this issue.

 Call in MS FLOW function url from HTTP action, select post or get method. My Visual Studio function works well. It is do word document from template. You do not need any credentials, URL works without it. I think you can do function with credentials, if you need. Pass and login are post or get params is https request.

I have the same issue. I am trying to call Azure functions in my PowerApps. How I can make it work?

I ran into the same issue. Later figured out that, we need to toggle the switch "Funciton app edit mode" from "Read Only" to "Read/Write". That should work.

@mnikam the solution suggested by you only works for Azure functions authored in the Azure Portal. 

If published through Visual Studio, these app settings / configurations are non-editable.
