logs/received
https://api.cloudflare.com/client/v4/zones/<ZONE_ID>/logs/received?start=<unix|rfc3339>&end=<unix|rfc3339>[&count=<int>][&sample=<float>][&fields=<FIELDS>][×tamps=<string>][&CVE-2021-44228=<boolean>]
logs/rayids/<RAY_ID>
https://api.cloudflare.com/client/v4/zones/<ZONE_ID>/logs/rayids/<RAY_ID>?[&fields=<string>][×tamps=<strings>]
The following table describes the parameters available:
| Parameter | Description | Applies to | Required |

| count | - Return up to that many records - Do not include if returning all records - Results are not sorted; therefore, different data for repeated requests is likely - Applies to number of total records returned, not number of sampled records | /logs/received | No |
| sample | - Return only a sample of records - Do not include if returning all records - Value can range from - - Results are random; therefore, different numbers of results for repeated requests are likely | /logs/received | No |
| fields | - Comma-separated list of fields to return - If empty, the default list is returned | /logs/received /logs/rayids | No |
| timestamps | - Format in which timestamp fields will be returned - Value options are: - Timestamps returned as integers for | /logs/received /logs/rayids | No |

Fields
Unless specified in the fields parameter, the API returns a limited set of log fields. This default field set may change at any time. The list of all available fields is at:
https://api.cloudflare.com/client/v4/zones/<ZONE_ID>/logs/received/fields
The order in which fields are specified does not matter, and the order of fields in the response is not specified.
Using bash subshell and jq, you can download the logs with all available fields without manually copying and pasting the fields into the request. For example:
curl -s \ -H "X-Auth-Email: <EMAIL>" \ -H "X-Auth-Key: <API_KEY>" \ "https://api.cloudflare.com/client/v4/zones/<ZONE_ID>/logs/received?start=2017-07-18T22:00:00Z&end=2017-07-18T22:01:00Z&count=1&fields=$(curl -s -H "X-Auth-Email: <EMAIL>" -H "X-Auth-Key: <API_KEY>" "https://api.cloudflare.com/client/v4/zones/<ZONE_ID>/logs/received/fields" | jq '. | to_entries[] | .key' -r | paste -sd "," -)"
