The project’s alert channels, the same ones as the dashboard’s Integrations page, sorted by name. Any role in the project can call it. A new check or tunnel is linked to every active channel of its project.

A channel’s settings, such as a bot token or a webhook address, are never returned. Making or editing a channel is done in the dashboard, under Integrations.

429

A usage limit was reached, or this IP address made too many requests with a wrong key.

Usage limits are per workspace and plan: per minute (Retry-After: 60), per day (Retry-After: 3600), and per month (no Retry-After). They use their own body shape. An IP address may send 10 wrong keys a minute; one more is allowed every 6 seconds. While that allowance is used up, every request from the address is refused, even one with a valid key.
