Indexing triggers allows immediate reindex of your repositories from remote systems, where near real-time data is sent to Jira whenever your git data changes. This provides Jira with more often up-to-date information. Setting up indexing triggers will result in a much faster indexing time where you don’t have to wait for the regular polling interval (every 5 minutes).
Most git providers will also allow you to create webhooks at an account-level or org-level. For more information about this topic, see About GitLab Webhooks.
Setup webhooks for your configured integration/repositories from remote systems by enabling the feature first.
From your Jira dashboard, go to the Apps menu.
Click Git Integration:Manage Git repositories.
On the sidebar, click Indexing triggers to open the Webhooks configuration page.
Turn on the webhook feature by switching the Indexing triggers enabled setting to ON.
Use the Webhook URL to setup webhook for your remote git host.
The Secret Key is a secure random-generated alphanumeric string at the time of the Git Integration for Jira app installation. The user can change this to a different value by generating another secret token according to your Git host.
