# 4. External system integration GeoPrism Registry supports integrating with external systems to help facilitate the exchange of data between systems. Registering an external system enables GeoPrism Registry to send data to an external system instance in a predictable way. This is useful to ensure that data in another system is using updated data from the curated data in GeoPrism Registry. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
