Custom Connector Post Action always endsup with Resource Not Found (404)

Posted on by Stef

I want to create a custom connector which is working perfectly fine with a GET action.

But as soon as i use PUT the test fails with the message:

{
"statusCode": 404,
"message": "Resource not found"
}

for testing purpos i tried ii with request.bin, but still same behavior. I can post to that ressource with postman.

is there something i'm missing?

Hi @Stef,

How you define the PUT (I think you mean POST here? ) action in the OpenAPI file?

Take a try to perform the corresponding actions in PostMan, then export the collection and import it into Custom connector builder.

Follow the article below:

Describe a custom connector with PostMan

Hi @v-micsh-msft

I found the solution. I have to add a body, nevertheless the API doesnt need one. And then its working.

What do you mean when you said I have to add a body? I'm facing the same issue.

@Stef I haven't tried this yet...
I am new to this. Where can I put this empty body to?
Here is my Get Action of the swagger file..

"get": { "summary": "GetContacts", "description": "GetContacts", "operationId": "GetContacts", "parameters": [ { "name": "Content-Type", "in": "header", "required": true, "type": "string", "default": " application/json", "description": "Content-Type" } ], "responses": { "200": { "description": "200", "schema": { "type": "object", "properties": { "@odata.context": { "type": "string", "description": "@odata.context" }, "value": { "type": "array", "items": { "type": "object", "properties": { "@odata.etag": { "type": "string", "description": "@odata.etag" }, "knk_ID": { "type": "string", "description": "ID" }, "No": { "type": "string", "description": "No" }, "Name": { "type": "string", "description": "Name" } } }, "description": "value" } } } } } }

I just wonder where I have to add this body.
I don't know where to put this information to custom connector.

I was getting this error too but my API was working fine on browser and postman. What worked for me was I just waited for 15 minutes and the error was gone. PowerApps takes some time to update the connector so if your API works on browser and still you're getting 404 then don't make any changes to your connector, don't delete and re create the connector, just wait for 15 minutes and it will work.
