clientKey

What's clientKey and how it’s used by the SPI

The clientKey in Atlassian Connect is an identifying key for the Atlassian product tenant that the app was installed into. It never changes for a tenant except when a Site import is performed on the Jira Cloud instance. This means that there can be multiple clientKeys for the same Jira Cloud instance. More details can be found here.

CMJ Cloud will invoke Apps' REST /wiki/spaces/AppIn/pages/143622222 with the most recent clientKey that corresponds to the base URL of the Jira Cloud instance the migration is running on.
