So i understand that there is an SLA of 15 minutes before the data in the entities who are inserted from Dynamics can be made available in Power Apps Portal. https://docs.microsoft.com/en-us/powerapps/maker/portals/admin/clear-server-side-cache
As per the documentation to get it faster you have to clear the cache i.e. click on browse website from the editor.
I digged a little and found that it actually sends a request to https://portalsitewide-nam.portal-infra.dynamics.com/api/v1/powerportal/ClearCache?portalId=xxx
is it possible to call this API from an external flow? With correct authorization token and other formalities. WE tried doing with the authorization token but didn't get successful maybe we are missing something in the token
