I am trying to figure out if we have options within CA Agile Central to be able to trigger a call to an external application when a defect is updated. Does anyone know?
This might be possible using Webhooks. Of course your external application would need to handle the JSON result appropriately. Here is a link to the Webhooks help page, which also contains the API documentation.

Let me know if that helps.
We have an Agile Central integration point to our CRM system for exactly this purpose but we didn't build it ourselves. We had CA Technical Services build out a connector that's based on similar architecture to the TFS connector and others that they've done before. It wasn't an enormous effort so if you don't have in-house resources to build something off the WSAPI then I'd advise contacting CA for a quote and more details. Hope that helps.
