I have created a custom connector by exporting it from Azure Logic Apps. At the time of using the connector in Power Automate Flow, I am getting the below mentioned error in the Manual-Invoke step of Custom connector.

Error:

The api-version query parameter (?api-version=) is required for all requests.

{

"error": {

"code": "MissingApiVersionParameter",

"message": "The api-version query parameter (?api-version=) is required for all requests."

}

I have tried this again by exporting the Logic App From Azure again to power apps as a new custom connectror. But when i am attaching my custom connector here , I am getting the same api version error. However, in the POST URL in the logicapp, the api-version is mentioned.(?api-version=2016-10-01&) .

Can anyone please help in identifying the main cause of this error or any kind of modifications that can be done to solve this issue.

Thanks in advance.

Is there any solution to it? If my flow is not used for some number of days, i get this error and it stops calling Logic app.

Hi,

I got this to work by manually adding these parameters to the swagger definition in the custom connector editor.

In your Power Platform Environment, open up Dataverse and Custom Connectors.
Click the Edit button for the Logic App connector
Toggle the Swagger Editor switch at the top
In the "Parameters" area add these parameters. Be sure the indentation is correct:

- {name: api-version, in: query, description: request version, required: true, type: string} - {name: sp, in: query, description: method, type: string, required: true} - {name: sv, in: query, description: method, type: string, required: true} - {name: sig, in: query, description: signature, required: true, type: string}

Go back to your flow and edit the manual-invoke action to add the required parameters from the URL in the Logic App. Decode the URL encoding from that url:

I was able to call the Logic App after this.

Hi,

Still the same problem. I've managed it by creating policies..
The values can be taken from the URL of the logic app:
