How to write custom connector that accepts a POST body?

(0) ShareShare

Posted on by camer314 173

I am writing a custom connector that has a very very simple POST method that just bounces back the exact content you sent it in the body. This works fine from everywhere except within PowerApps itself.

 

Here is my server side code:

This is the resulting Swagger:

And this is the error I get in Flow when I try and use it.

Does anybody know whats going on? It seems like the most basic of use cases ever!

    Hi @camer314 :

    In the screenshot you provided, I noticed that the error message "invaild input parameters".Could you check the setting of the parameter 'body' in the custom connector?

    whether the parameter value {"A":"B"} you expected is a string or an object?As far as I know,parameter does not support value of type object.

    I found some related links, hope they are useful to you:

    Create a custom connector from an OpenAPI definition 

    Custom Connector: Header "content-type" not sent to service 

    Custom connector action with x-www-form-urlencoded content-type 

    Best Regards,
