Why did my webhook volume suddenly spike?

Large webhook bursts are expected recovery traffic, not invalid requests.

Large webhook bursts are expected recovery traffic, not invalid requests. They typically follow an interruption: when delivery to your endpoint is down, Terra keeps retrying, and the data accumulated for that period is sent in bulk once your service resumes. This can recur after any future interruption.

Put a queue or buffer in front of your webhook consumer so bursts do not overload your database writes.

If a user_id looks malformed in the dashboard, that is a display-only issue. The actual payload always carries the real identifier, and user_id is documented as an arbitrary string, not strictly a UUID.
