Call an external service when the database changes to Read-Only mode
Business case
A 3rd party system is used to add and modify data in real time using Mambu's REST APIs. In certain cases, such as during regular scheduled maintenance or for updates, the database may be switched to read only mode. In a 'fire and forget' style implementation this could cause data to be lost as the sending system will have no persistent records. Using a webhook that is triggered when the database access state changes, you could queue calls or pause this system until write access has been reenabled.
Configuration
