Using an "if" statement with curl

I am using below curl command to restart the Connectors/tasks. I have scheduled this curl command in Crontab. The purpose of this curl command is to restart the Connectors/Tasks, if their status is "Failure". I would like to incorporate "if" statement in this curl command, so that it attempts only 3 times in order to restart the Connectors/Tasks. After attempting 3 times, it has to stop the restarting the connectors/tasks and send an Email.

curl -s "http://localhost:8083/connectors?expand=status" |
jq -c -M 'map({name: .status.name } + {tasks: .status.tasks}) | .[] | {task: ((.tasks[]) + {name: .name})} | select(.task.state=="FAILED") | {name: .task.name, task_id: .task.id|tostring} | ("/connectors/"+ .name + "/tasks/" + .task_id + "/restart")' |
xargs -I{connector_and_task} curl -v -X POST "http://localhost:8083"{connector_and_task}

Could you please give me the solution
