In case of the installation secret being out of sync
There are various of reasons that the installation secret can be desynchronized. In such a case, consider going with the following viable options upon your requirements:
Action | Resolution time | Blast radius | End-user interactions |
|---|---|---|---|
Bump up the micro version of your app so that the daily lifecycle event can send a newly issued secret | Up to 33 hours | All sites where the app is installed | Not required |
Request an administrator of the site to uninstall and reinstall the app, which will send a new secret immediately | As soon as the app is reinstalled | Only one specific site | Manual operation from the administrator is required |
Submit a Developer Support ticket requesting a single site to be reset | Depends upon the ticket's resolution time | Only one specific site | Not required |
