The Pull from file queue step receives a file URL (CSV, PDF, or Excel) along with associated metadata, and triggers the flow to run. It’s the right pattern when you need to process many files in sequence, fanning out from another flow, or being driven by an external system. Available on the Advanced plan.

Sending a file to your Prowork flow

The file queue processes files that are accessible by URL. To send a file in, make a POST to the file queue endpoint shown in the step’s settings modal:
Any valid POST triggers a flow run. The flow uses the file parsing settings on the step to read the file. Additional requests queue up and run in order. You can also trigger the queue from another Prowork flow. Use the Run another Prowork flow step set to Run once per row with a file URL: every column from the originating row is “splatted” onto each row fetched by Pull from file queue, so the downstream flow has full context from upstream.
