Azure Synapse API returns empty array with filters in POST request, but works without them

Question

I'm trying to query pipeline runs in Azure Synapse using the Synapse REST API (queryPipelineRuns). When I make a POST request without filters in the body, it works and returns the expected pipeline runs. However, when I add filters such as lastUpdatedAfter or others (e.g., Status, PipelineName), the response is always an empty array [].

Here’s my POST request body that is returning an empty result:

{

"method": "POST", "headers": { "Content-Type": "application/json" },

"url": "https://WorkspaceName.dev.azuresynapse.net/queryPipelineRuns?api-version=2020-12-01", "connectVia": { "referenceName": "AutoResolveIntegrationRuntime", "type": "IntegrationRuntimeReference" },

"body": { "lastUpdatedAfter": "2024-06-16T00:36:44.3345758Z" },

"authentication": { "type": "MSI", "resource": "https://dev.azuresynapse.net" }

}

Answer 1

According to the MS document lastUpdatedAfter and lastUpdatedBefore are mandatory fields while applying filter. So, in the request body provide the value as below:

{     "lastUpdatedAfter": "2024-06-16T00:36:44.3345758Z",   
  "lastUpdatedBefore": "2025-06-16T00:49:48.3686473Z"   
}
