Tyk Policies API
Policies are a template that enable you to create access rules, usage quota and rate limits that can be applied to multiple keys. They are a useful way to manage large groups of users, and to enforce quota changes on a global scale across any number of keys that are using a policy. When used in conjunction with the portal, developers that enroll for API access will be given a key that is attached to a specific policy. The policy settings are refreshed every time a key attempts access, meaning that updating a policy will have an effect across any keys that are attached to it.
