Webhook and application links

[Amali]

Team,
I'd like to understand the difference between webhook and application links and how different it is from each other.
We have a requirement where if one Jira instance creates/updates an issue, the other instance should create/update accordingly.
Emailing back and forth wouldn't really work here. I'm trying to understand the difference between webhooks and application links and their application specifically to this use case.

Hi @Amali 

thanks for your question. I'm trying to explain the differences:

webhooks can be configured to push the whole issue data (status, custom fields, ...) to a specific URL. They can be configured to specific issue updates like create or update for example.

application links work as a connection between two (Jira) instances. They allow to link issue ABC-1 from instance A to XYZ-1 from instance B. 

If you want to sync two instances, there are several apps in the marketplace that solve this exact problem. Two examples are:

Backbone Issue Sync

Issue Sync - Synchronization for Jira

Hope this helps.
