Getting Started

Requirements

• WordPress 6.4+
• PHP 8.0+
• A Cloudflare-proxied domain (orange cloud ☁️ enabled in DNS)

Installation

1. Download RelayWP from the WordPress plugin repository:

   wp plugin install tagpurge --activate
   

   Or install via Plugins → Add New and search for “RelayWP”.

2. Go to Settings → RelayWP in your WordPress admin.

3. Enter your Cloudflare Zone ID and API Token.

   • Zone ID: Found in your Cloudflare dashboard under Overview → Zone ID
   • API Token: Create one at Cloudflare → My Profile → API Tokens. Required permissions: Zone.Cache Purge (Edit) + Zone.Zone (Read)

4. Click Test Connection to verify your credentials.

Cloudflare Page Rules

Ensure your Cloudflare cache level is set to Cache Everything for your origin (or use a Cache Rule). RelayWP only purges — it does not control what gets cached.

Cache-Tag header

After activation, visit any post and check the response headers:

Cache-Tag: post:42,author:7,category:news,feed:post,page:home

This confirms tag injection is working.
