+## Pagination
+
+The API uses _keyset pagination model_. It means that there are ids of next and previous page attached to every response, in its `meta` section:
+```json
+{
+  "meta": {
+    "previousPageId": "QVl3ZUp3RzRRTzBBOWdBQUFIaXFJQUVRQVFBQWlKVUJBSitHQVFBPQ==",
+    "nextPageId": "QUl3ZUp3SEJRTzBBZUFBQUFIaXFJQUVRQVFBQWlKVUJBSitHQVFBPQ=="
+  }
+}
+```
+To fetch another page, you have to set `pageId` in your request to one of the returned ids.
+If there is no previous page, `previousPageId` will be `null`. Similarly, the request for the latest page will return `null` as  `nextPageId`.
+
+If `pageId` is not set, the API returns the **latest** page.
+You can set `pageId` to `"earliest"` to fetch the earliest page.
