Sourcing API (/quote_requests)

Use the Coupa Sourcing API to create new RFx events, see supplier responses, and award suppliers at the line level.


Use the sourcing API to:

  1. Create RFP, RFI, or RFQ type events.
  2. Extract supplier responses to the event.
  3. Award events to suppliers at the line level.

For the Coupa back end, a sourcing event is known as a quote request.


The following endpoints are available for sourcing API.

Resource Path Description
Sourcing events


Endpoint for creating new sourcing events and managing existing events
Supplier responses


Endpoint for working with supplier responses
Sourcing suppliers


Endpoint for getting info about suppliers on a sourcing event

Example calls

Create a new sourcing event

POST /api/quote_requests/

To create a new event, you can send a basic POST. Include the <event-type> element or else Coupa will default to an RFI.


<?xml version="1.0" encoding="UTF-8" ?>
	<event-type type="symbol">RFQ</event-type>
