 The following page can be retrieved by providing the cursor returned in the previous call response:
 
 ```bash
-curl https://eu.api.ovh.com/v2/iam/policy -H "X-Pagination-Size: 5" -H `X-Pagination-Cursor: xxxyyzzz"
+curl https://eu.api.ovh.com/v2/iam/policy -H "X-Pagination-Size: 5" -H "X-Pagination-Cursor: xxxyyzzz"
