 Additionally, any path parameters must be URL encoded. For example, any slashes in the parameter value must be replaced with `%2F`. If you don't properly encode any slashes in the parameter name, the endpoint URL will be misinterpreted.
 
+You should also confirm that you are using an HTTP method that the endpoint supports. If you send a request with an HTTP method that the endpoint does not support, you will receive a `404 Not Found` response instead of `405 Method Not Allowed`. For example, sending a `DELETE` request to an endpoint that only supports `GET` will result in a `404 Not Found` response. You can refer to the reference documentation for the endpoint to confirm the supported HTTP method.

 ## Missing results
 
 Most endpoints that return a list of resources support pagination. For most of these endpoints, only the first 30 resources are returned by default. In order to see all of the resources, you need to paginate through the results. For more information, see [AUTOTITLE](/rest/using-the-rest-api/using-pagination-in-the-rest-api).

 If an endpoint supports the `per_page` query parameter, then you can control how many results are returned on a page. For more information about query parameters see [AUTOTITLE](/rest/using-the-rest-api/getting-started-with-the-rest-api#query-parameters).
 
+For most endpoints, the maximum value of `per_page` is `100`. If you specify a value greater than the maximum, {% data variables.product.company_short %} does not return an error. Instead, the value is automatically reduced to the maximum, and the response includes no more than the maximum number of results per page. Because the request still succeeds, you may receive fewer results than you expect without any indication that the `per_page` value was reduced. To confirm the default and maximum `per_page` values for an endpoint, see the reference documentation for that endpoint.

 For example, this request uses the `per_page` query parameter to return two items per page:
