KV Store is a lightweight, server-side key-value database for your app. Use it to cache data, ensure webhook idempotency, or store transient server state. It’s available in server functions, webhook handlers, and event handlers.
The KV Store is experimental and may change in the future. Please don’t use it in production versions of your app. We do not guarantee backward compatibility, or that the API will remain stable.

​
Example: Caching a response from an external API

When your app calls an external API, you don’t always need to fetch fresh data every time. With the KV Store, you can cache the response and set a TTL so it clears itself after a certain period of time.
get-users.server.ts
import { experimental_kv } from "attio/server";

export default async function getAllUsers() {
  const users = await experimental_kv.get("users");

  if (users !== null) {
    return users.value;
  }

  const response = await fetch("https://api.emailsequence.com/v1/users");
  const data = await response.json();
  await experimental_kv.set("users", data, { ttlInSeconds: 60 * 60 * 24 * 30 });
  return data;
}
