Custom Connector- 404 Resource Not Found

Dear Sir/Madam,


We have setup the Custom Connector, and we are successfully retrieve the record by calling the GET request to the data services.  However, when we tried to upload the records to the data services and the 404 operation failed was returned.  We had tried to submit the request by using command line curl and it works fine as below:


c:\curl\bin>curl -i -H "Content-Type: application/json" -X POST -d @Test2.json ""
HTTP/1.1 201 Created
Date: Wed, 03 Jul 2019 15:26:28 GMT
Content-Type: application/json
Transfer-Encoding: chunked
Connection: keep-alive

The configuration of the Custom Connector is as attached and please help to fix the issue.  Thanks.

Re: Custom Connector- 404 Resource Not Found

Hi @Makjimmy ,

Is the "" your host name of your API Service?

Which authentication type do you use within your custom connector? No Authentication?

Further, is your data service installed on your local machine?


If your data service is deployed within cloud, you do not need to enable the "Connect via on-premises data gateway" option as below:1.JPG


If your data service is installed within your local machine, please consider provide a proper Authentication type within your custom connector to connect to your data service.


Also please check if you have typed a proper Request URL and Request Body within your custom connector to execute the POST action.


More details about creating a custom connector in PowerApps, please check the following article:
