Learn how to protect workflow systems from abuse, leaks, and accidental expensive runs.
API keys and private tokens belong on the server. They should not be placed in frontend code, browser storage, URLs, logs, or public repositories.
Webhook endpoints should verify the sender before taking action. Signatures, timestamps, delivery IDs, and replay protection reduce abuse.
Automations should have limits, retries, and human approval points so they do not run unexpectedly or create unnecessary cost.
Review a workflow idea and list every secret, external event, expensive action, and place where logs might contain private data.
