The step that gives the error is the Invoke an HTTP request. As far as I can tell my configuration is correct. I have provided the raw input and output below in case this helps at all. +++++++++ RAW INPUT: +++++++++ { "host": { "connectionReferenceName": "shared_webcontents", "operationId": "InvokeHttp" }, "parameters": { "request/method": "POST", "request/url": "/api/data/v9.0/ExportToExcel", "request/body": "{\n \"View\": {\n \"@odata.type\": \"Microsoft.Dynamics.CRM.savedquery\",\n \"savedqueryid\": \"00000000-0000-0000-00aa-000010001004\"\n },\n \"FetchXml\": \"\",\n \"LayoutXml\": \"\",\n \"QueryApi\": \"\",\n \"QueryParameters\": {\n \"Arguments\": {\n \"Count\": 0,\n \"IsReadOnly\": true,\n \"Keys\": [],\n \"Values\": []\n }\n }\n}" } }
