Documented steps
Get the zone ID (zone Overview tab) and an API token carrying the 'Cache Purge' permission group scoped to that zone.
Send POST https://api.cloudflare.com/client/v4/zones/{zone_id}/purge_cache with headers `Authorization: Bearer $CLOUDFLARE_API_TOKEN` and `Content-Type: application/json`.
Purge everything: body {"purge_everything": true}.
Purge individual files: body {"files":["https://www.example.com/css/styles.css"]}. Entries may instead be objects {"url":"...","headers":{"CF-IPCountry":"US","CF-Device-Type":"desktop","Accept-Language":"zh-CN"}} to target cache keys that vary on those headers.
Purge by cache-tag: body {"tags":["a-cache-tag","another-cache-tag"]}. This only works if the origin sent a Cache-Tag response header when the content was cached. Tags are case-insensitive printable ASCII, max 1,024 chars per tag, with a 16 KB aggregate Cache-Tag header cap (~1,000 unique tags).
Purge by hostname: body {"hosts":["www.example.com","images.example.com"]}.
Purge by prefix: body {"prefixes":["www.example.com/foo","images.example.com/bar/baz"]}.
Supply exactly one purge mode per request — purge_everything, files, tags, hosts and prefixes cannot be combined in a single call.
Read the envelope {"success":bool,"errors":[],"messages":[],"result":{"id":"<32-char-id>"}}. success:true means the purge was accepted; propagation across the edge is asynchronous.

Known gotchas
Only one purge mode is accepted per API call; mixing files and tags in one body is rejected.
Hostname / tag / prefix / purge-everything share an account-wide token-bucket rate limit that differs by plan (Free 5 req/min, Pro 5 req/sec, Business 10 req/sec, Enterprise 50 req/sec), each capped at up to 100 operations per request.
Single-file purge has separate, higher limits (Free 800 URLs/sec, Pro/Business 1,500 URLs/sec, Enterprise 3,000 URLs/sec) with up to 100 operations per request on Free/Pro/Business and up to 500 on Enterprise.
Purge-by-tag only affects content that was cached with a Cache-Tag response header; adding the header after the fact does not make already-cached objects purgeable by tag.
A purge forces a MISS on the next request (CF-Cache-Status: MISS) rather than synchronously deleting content — verify with a subsequent request, not with the API response alone.
Plan gating differs from rate-limit headroom; check the current plan-specific limit table rather than assuming tag/prefix/hostname purge is Enterprise-only.
