PHP hooks reference

Deprecated: PHP hooks for extensibility have been removed from Veyo. For custom development needs, contact our custom development team or reach out to support@veyodesigner.com.

This documentation is kept for reference only. Server-side extension points for addon bootstrap.php files are no longer supported. Use custom development services for specialized integrations.

Registering a hook

<?php
// plugins/my-addon/bootstrap.php

VeyopHooks::addFilter('veyo_pricing_components', function ($components, $context) {
    $components[] = [
        'label' => 'My Addon Fee',
        'amount' => 1.50,
    ];
    return $components;
}, 10, 2);

VeyopHooks::addAction('veyop_design_saved', function ($design, $context) {
    // e.g. write an audit log entry
});

These calls also work as plain WordPress add_filter / add_action on a WordPress site — VeyopHooks is a thin portable wrapper, not a replacement API you must learn from scratch.

Filters

Filter	Purpose
`veyo_admin_menus`	Add or modify entries in the Product Personalizer admin menu.
`veyo_product_settings`	Modify the designer config payload sent to the front-end Vue app for a product (legacy alias: `veyop_designer_config`).
`veyo_custom_css`	Append or modify custom CSS injected into the designer.
`veyo_inline_styles`	Modify inline style output for the designer shell.
`veyo_calculate_custom_price`	Adjust the computed personalization price for a design.
`veyo_cart_item_data`	Add or modify custom data attached to a WooCommerce cart item.
`veyo_order_item_meta`	Add or modify order line-item meta saved with a design.
`veyo_pricing_components`	Return additional validated pricing line items for a quote. Core owns the final arithmetic — addons only contribute components.
`veyop_addon_should_load_file`	Control whether a specific addon asset file should load for the current request.
`veyop_addon_designer_assets`	Modify the list of designer JS/CSS assets enqueued for enabled addons.
`veyop_export_item_svg`	Modify the SVG fragment generated for a single design item during export.
`veyop_export_composed_svg`	Modify the fully composed SVG for a view before rasterization.
`veyop_export_format_handlers`	Register a custom export format handler (e.g. an embroidery `.dst` writer).
`veyop_design_record_resolve`	Modify how a saved design record is resolved/loaded.
`veyop_design_save_data`	Modify the data payload written when a design is saved.
`veyop_designer_calculate_price`	Lower-level hook into the designer's price calculation, upstream of `veyo_pricing_components`.
`veyop_themes_discovered`	Modify the list of discovered designer UI themes.
`veyop_active_theme_slug` / `veyop_active_theme`	Override which designer theme is active.
`veyop_theme_should_load_file`	Control whether a specific theme asset file loads.
`veyop_theme_designer_assets`	Modify assets enqueued for the active theme.
`veyop_designer_theme_config`	Modify the theme configuration payload sent to the designer.

Actions

Action	Fires
`veyo_before_customer_design_view`	Before the customer-facing designer renders on a product page.
`veyo_after_customer_design_view`	After the customer-facing designer renders.
`veyo_product_personalizer_menu`	While the admin menu is being built — a lower-level companion to the `veyo_admin_menus` filter.
`veyop_addons_discovered`	After core finishes scanning `plugins/` for addon packages.
`veyop_addon_before_include` / `veyop_addon_after_include`	Immediately before/after an enabled addon's server entrypoint is loaded.
`veyop_order_item_design_saved`	After a design is attached to a WooCommerce order line item.
`veyop_design_saved`	Whenever a customer design is saved (draft or final).
`veyop_theme_before_include` / `veyop_theme_after_include`	Immediately before/after a designer theme's files load.

REST route registration

Don't register your own rest_api_init hook. Core dispatches a single veyop_register_rest_routes action from its own rest_api_init handler — hang your register_rest_route() calls off that instead, so every addon's routes register in one place and in a predictable order. See REST API reference.
