Azure Devops webhook & Grafana


I am using Azure DevOps and I would like to show the result of deployment on Grafana.
Azure Devops has a webhook service and we can easilty add Grafana. Fx if a deploy fails, It post a json event to my grafana endpoint http://*******:3000/api/annotations.

Right now I am able to receive something like that from Azure Devops.

But I am not able to dig into the json data that I get from Azure devOps.
Honesty I start to work with Grafana for 2 weeks and I am very new to it.

Can someone help me in order to get access to a specific json property and show it in a table? Basically I would like to show the result of build if it successful or not.

Appreciat it &
Thanks a lot.
