Passing Parameters to a fabric pipeline via the API

[richanthony]

I have successfully call a data flow from power automate using an HTTP connector and this basic URL https://api.fabric.microsoft.com/v1/workspaces/@{variables('WorkspaceID')}/items/@{variables('Pipeli....

However this won't pass a parameter in to the pipeline which I need it to do, has anyone got any ideas on how to pass an parameter in to a dataflow via the API. the documenation is not great for this.

You would use a POST call instead of a GET and specify your parameters in the body payload.

As @lbendlin says, parameters should be able to be passed in throught the payload of the POST request.
Here's a Medium.com article on it - although I'm trying to use sempy_labs instead.

I am however getting a 404 back from the server and although the pipeline is triggering, it's not passing the parameter in.

FabricHTTPException: 404 Not Found for url: https://api.fabric.microsoft.com/v1/operations/<guid> Error: {"requestId":"<guid>","errorCode":"NotFound","message":"The endpoint or resource could not be found"}

I followed this link and found that the body I was using was not correct this format worked:

{
"executionData": {
"parameters": {
"Param1": "value1",
"Param2": 123,
"Param3": true
}
}
}
