Tyk enables you to actively monitor both users and organization quotas. The machinery that manages these active notifications is the same as webhooks and provides an easy way to notify your stakeholders, your own organization or the API end user when certain thresholds have been reached for their token.

Enabling Monitors In Your Tyk Node?

Enabling monitors in your Tyk node means adding a new configuration section to your tyk.conf:

"monitor": {
  "enable_trigger_monitors": true,
  "configuration": {
    "method": "POST",
    "target_path": "",
    "template_path": "templates/monitor_template.json",
    "header_map": {"x-tyk-monitor-secret": "12345"},
    "event_timeout": 10
  "global_trigger_limit": 80.0,
  "monitor_user_keys": false,
  "monitor_org_keys": true
  • enable_trigger_monitors: Set to true to have the monitors start to measure quota thresholds.
  • configuration: A webhook configuration object, please see the webhooks documentation for details.
  • global_trigger_limit: This is the global trigger threshold and will be applied to all tokens being measured. This number is a percentage of the quota that the user must reach before the notification is triggered.


From Dashboard v1.8.2, if you are using our Developer Portal, developers registered in the portal will also receive emails about quota threshold limits being reached.

  • monitor_user_keys: Set to true to monitor individual tokens, this may result in a large amount of webhooks.
  • monitor_org_keys: Set to true to have global organization quotas monitored.

Setting custom triggers on a per-key or a per-organization basis

Sometimes you will not want to have every user have a trigger event at the same levels, you can set manual trigger levels by adding a monitor section to the Session Object that defines a key’s access details, this can also be added to the session object of an organization ID:

"monitor": {
  "trigger_limits": [80.0, 60.0, 50.0]

The trigger_limits must be in descending order and represent the percentage of the quota that must be reached in order for the trigger to be fired.

Webhook data

The webhook payload will take the following format:

  "event": "TriggerExceeded",
  "message": "Quota trigger reached",
  "org": "53ac07777cbb8c2d53000002",
  "key": "",
  "trigger_limit": "80",

If the event is triggered by an organization, then the key field will be empty, if it is an auth token, then the key field will have raw representation of the token that caused the quota trigger to fire.
