How to verify that post-commit hook worked?

[ahumaidat]

I'm using this request:

/usr/bin/curl -X PUT -H "X-Api-Key: $key" -H "Content-Type: application/json" -m 20 "$URL/fecru/rest-service-fecru/admin/repositories/$repo/incremental-index"

The request returns nothing, and when checking the Maintenance tab for the repo, Last index update shows that it was updated 2 hours ago.

Do I need to stop automatic polling to test the hook?
