Two ways to exercise a webhook endpoint without touching production data: the dashboard’s Send test event button, and pivotal_test_ API keys.
Test events from this button carry livemode: false and a fake resource id. They will not appear in your Pivotal app’s activity feed.
pivotal_test_… keys write to the same workspace, but outbound integration side effects (Slack, Resend, downstream webhook deliveries to your live receivers) are suppressed. Webhook endpoints flagged test_mode: true receive these events; live endpoints do not.
See Test mode for the full rules.
Pair the Webhooks dashboard with a local tunnel — see Local tunneling. The flow:
localhost:8787.
