Custom connector: dropdown advanced options

(1) Share

Report

Posted on by Kol

I'm creating a connector in which one of the fields is about a language ID. Our API takes an integer, where for instance 1 is for English, 2 is for French etc.

It's not practical for users to have to research what is the ID of their language, so I wanted to do a dropdown where they would select the name of the language and it would send the corresponding ID to the API.

Eg: "English => 1", "French => 2", etc.

However, I don't understand if I can do that in Flows.

We don't have an API call that would return this information, so I can't create an action about it, and thus I can't use a dynamic dropdown.

Is there a way to do this in a static dropdown?

Hey @Kol
How are you creating your endpoint for the connector?
We typically use .Net Core Web APIs (C#)... if you're doing the same you should just be able to use an enum, the default JSON serialization would simply support this approach, your swagger defintion would simply contain something like. which flow would render has a drop down.
"HorizontalAlignment": { "default": "Center", "enum": [ "None", "Left", "Center", "Right", "Justify", "FullJustify" ],

Hi @Kol,
You may add following editor option extension to parameter properties to support your scenario:
{ "name": "language", "in": "query", "required": false, "x-ms-summary": "Language", "type": "string", "default": "1", "enum": [ "1", "2" ], "x-ms-editor-options": { "items": [ { "title": "English", "value": "1" }, { "title": "French", "value": "2" } ] } }

Doesn't work with flag enableOpenApiConnection. If it is set to true, the titles are not being displayed, only the values.

I wonder, when MS will start documenting all this?
