Filter Hooks

This reference targets APD v1.0.x. Last updated: 2026-02-25.

100+ filter hooks to modify listing data, queries, submissions, fields, templates, emails, REST API responses, and more. Each hook includes its parameters and a code example.

Security notes for integrations

Filter callbacks that trigger write operations should validate a nonce using wp_verify_nonce() or, in REST contexts, wp_verify_nonce( $value, 'wp_rest' ).
Always escape output values returned from filters and sanitize any external input before returning it.

Hook stability: All hooks listed on this page are part of the public API and follow semantic versioning. Hooks will not be removed or have their signatures changed in minor or patch releases. Deprecated hooks will be announced at least one minor version before removal.
