This document describes the Interinstitutional Agreement CNR API. This API can be implemented by all EWP partners, and will be called by some other EWP partners whenever related IIAs are changed on their side. It allows the partners to listen for changes in other copies of their IIAs kept in the EWP Network.
CNR stands for Change Notification Receiver. For a detailed introduction on how CNR APIs work, please read this page.
- Requests MUST be made with HTTP POST method. Servers MAY reject all other request methods.
Parameters MUST be provided in the regular application/x-www-form-urlencoded
format.
Identifier of the IIA which has recently been changed (created, updated or deleted) by the calling HEI.
This version of this API uses standard EWP Authentication and Security, Version 2. Server implementers choose which security methods they support by declaring them in their Manifest API entry.
-
General error handling rules apply.
-
Servers MUST return a valid (HTTP 200) XML response whenever the request has been properly received. Unless HTTP 200 is received, clients are RECOMMENDED to automatically retry the request after some time.
Servers MUST respond with a valid XML document described by the response.xsd schema. See the schema annotations for further information.
It is NOT guaranteed that all notifications will be delivered to you promptly. Some notifications may also not reach you at all, e.g. due to implementation errors on the sending institution's server.
