Querying Firewall Events with GraphQL

In this example, we're going to use the GraphQL Analytics API to query for Firewall Events over a specified time period.

The following API call will request Firewall Events over a one hour period, and output the requested fields. Be sure to replace CLOUDFLARE_ZONE_ID, CLOUDFLARE_EMAIL, and CLOUDFLARE_API_KEY with your zone tag and API credentials, and adjust the datetime_geg and datetime_leq values to your liking.

API Call

PAYLOAD='{ "query":
"query ListFirewallEvents($zoneTag: string, $filter: FirewallEventsAdaptiveFilter_InputObject) {
viewer {
zones(filter: { zoneTag: $zoneTag }) {
firewallEventsAdaptive(
filter: $filter
limit: 10
orderBy: [datetime_DESC]
) {
action
clientAsn
clientCountryName
clientIP
clientRequestPath
clientRequestQuery
datetime
source
userAgent
}
}
}
}",
"variables": {
"zoneTag": "CLOUDFLARE_ZONE_ID",
"filter": {
"datetime_geq": "2020-04-24T11:00:00Z",
"datetime_leq": "2020-04-24T12:00:00Z"
}
}
}'
curl \
-X POST \
-H "Content-Type: application/json" \
-H "X-Auth-Email: CLOUDFLARE_EMAIL" \
-H "X-Auth-key: CLOUDFLARE_API_KEY" \
--data "$(echo $PAYLOAD)" \
https://api.cloudflare.com/client/v4/graphql/

The results returned will be in JSON (as requested), so piping the output to jq will make them easier to read, e.g.,:

curl \
-X POST \
-H "Content-Type: application/json" \
-H "X-Auth-Email: CLOUDFLARE_EMAIL" \
-H "X-Auth-key: CLOUDFLARE_API_KEY" \
--data "$(echo $PAYLOAD)" \
