1.8 EHI Data Feeds

The EHI can be used as a source of read-only transactional data. For each transaction that Thredd processed, the EHI sends a notification message to your external host system (i.e., to the external host URL endpoint you have requested for your programme). The notification message contains all key attributes of the processed transaction. As with the authorisation advice, the notifications are sent to the external host in real time.

The sections below list the most important fields for each type of message. For details of all the fields in the GetTransaction message, see GetTransaction Messages. For details of the fields in the Cut Off message, see Cut Off Message.
