Caching

Read caching behavior and automatic invalidation on writes.

GET responses for a single subscriber and for subscriber lists are cached for up to 1 hour.

What this means for you

• After creating, updating or unsubscribing a subscriber, the relevant cached reads are invalidated automatically, so your next read reflects the change.
• In the absence of a write, a GET may return data up to 1 hour old.
