+#### Using pagination
+
+Pagination can be used when API returns Data as array type.
+There is 2 options: `limit` and `offset`.
+You can find such request example [here](https://dev.mailjet.com/email/reference/contacts/contact/#v3_get_contact).
+Next example returns 40 contacts starting from 50 record:
+
+```python
+import os
+from mailjet_rest import Client
+
+api_key = os.environ["MJ_APIKEY_PUBLIC"]
+api_secret = os.environ["MJ_APIKEY_PRIVATE"]
+mailjet = Client(auth=(api_key, api_secret))
+
+filters = {
+    "limit": 40,
+    "offset": 50,
+}
+result = mailjet.contact.get(filters=filters)
+print(result.status_code)
+print(result.json())
+```
