Submit file for the current step of a flow

This endpoint uploads a file for the active step in a flow to confirm the file is correctly uploaded for the current step. Submit the file in the request body using multipart/form-data.

Path parameters in the header must include both the flowId which identifies the workflow, and the x-hf-session which is the UUID for the user state within that workflow.

Optional parameters can also include x-hf-language which is the language for execution of the workflow.

Document Types

The list of allowed documents can be set when adding the File Field to a form in a workflow. When accessing the workflow via API, the Get current step response will contain the list of document types allowed for upload.
