Pass input file path in Alteryx Gallery API

snigdha25 — Wed, 14 Feb 2024 11:45:17 GMT

I am using Alteryx Gallery API (POST /v1/workflows/{appId}/jobs) to execute a workflow.
I am passing the file path as value but I keep getting the error - "The Action \"ToolId:3\" has an error: The file name is empty."

How should the file path be passed so that it is read by API.

Attached image of value that I am passing.

Hi,

I think you need to first use this endpoint (POST) - /user/v2/inputfiles/- to publish a temporary file to be used as an input to an Analytic App.

Regards.

API Documentation:

Implementation Notes
Use a MultiPart/Form-Data request to publish a temporary file to be used as an input to an Analytic App. The name of the required form-data section is inputFile.

--FORM-BOUNDARY
Content-Disposition: form-data; name="inputFile"; filename={fileName}
Content-Type: {contentType}
{fileContents}
--FORM-BOUNDARY

Use the fileId returned as an input parameter in an Analytic App.

HI,

I'm joining this thread to ask you: what exactly should I enter in this form?

--FORM-BOUNDARY
Content-Disposition: form-data; name="inputFile"; filename={fileName}
Content-Type: {contentType}
{fileContents}
--FORM-BOUNDARY

fileName is the path of the file I want to upload?

what are "contentType" and "fileContents" fields?

Thank you very much for your help!
