curl \

--header "Content-Type: application/json" \

you can get the webhook url in google chat by gchat channel -> Apps & Integrations -> manage webhooks

&threadKey=pipeline-notifications

if you want all notification in the same thread add a freely chosen value for “threadKey” (eg. pipeline-notifications)

problem: sequential jobs If you are running your jobs sequentially it is not possible to run a final job unconditionally. https://discuss.circleci.com/t/how-to-always-run-a-sequential-final-job-e-g-slack-notification/35362

solution: add the notify_failure at the end of EVERY job’s steps list
