feat: add Sender (sender.net) email marketing integration

[RishadAlam]

Description

Adds a new Sender (sender.net) action integration. Users can connect a Sender account with an API token and push trigger data into Sender as subscriber and group operations. The free plugin handles authorization, group/custom-field fetching, and field mapping; the actual API calls are delegated to Bit Integrations Pro via hooks.

Motivation & Context

Extends the available email-marketing destinations so users can automate subscriber and group management in Sender directly from any Bit Integrations trigger.

Key Changes

Integrations (Backend)

• Added SenderController — API-token authorization (verified against the /groups endpoint), refreshGroups and refreshFields AJAX handlers, and the Flow execute() entry point.
• Added RecordApiHelper — builds request data from the field map and routes each of the 9 actions to Pro via Hooks::apply(), with success/error logging through LogHandler.
• Added Routes.php — registers the auth/refresh AJAX endpoints.
• Added Custom-field token handling — converts Sender {{slug}} tokens to {$slug} personalization form and excludes default fields (email/firstname/lastname/phone) from custom-field mapping.

Supported Actions

• Create or update subscriber, update subscriber, delete subscriber, remove phone from subscriber
• Add/remove subscriber to/from group
• Create group, update group, delete group

Frontend

• Added Sender wizard — Sender.jsx, SenderAuthorization.jsx, SenderActions.jsx, SenderIntegLayout.jsx, SenderFieldMap.jsx, EditSender.jsx, SenderCommonFunc.js, staticData.js.
• Added Integration registration in NewInteg.jsx, EditInteg.jsx, IntegInfo.jsx, SelectAction.jsx, plus tutorial link and sender.webp icon.

Checklist

• Code follows project style guidelines
• Self-review completed

• README updated if needed

Changelog

• New Actions: Sender (sender.net) — manage subscribers and groups (create/update/delete subscriber, remove phone, add/remove subscriber to group, create/update/delete group)

Code Review

This pull request introduces a new integration for Sender (sender.net), adding backend PHP controllers, helpers, and routes, alongside frontend React components for authorization, field mapping, and action configuration. A critical issue was identified in RecordApiHelper.php where a potential WP_Error response is accessed as an array without validation, which can lead to a fatal error in PHP 8.0+.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

In PHP 8.0+, accessing a WP_Error object as an array (e.g., $response['success']) will trigger a fatal error. Since Hooks::apply can return a WP_Error object, you must validate the response using is_wp_error() before attempting array access.

        $responseType = !is_wp_error($response) && isset($response['success']) && $response['success'] ? 'success' : 'error';

References

1. In PHP, when handling responses that may return a WP_Error object, always use the is_wp_error() function to validate the response before accessing it as an array or object. This prevents fatal errors in PHP 8.0+.

[RishadAlam]

Good catch — verified on PHP 8.4 that isset($wpError['success']) throws Error: Cannot use object of type WP_Error as array, so this was a real fatal risk when the Pro hook returns a WP_Error. Added an is_wp_error() guard:

$responseType = !is_wp_error($response) && isset($response['success']) && $response['success'] ? 'success' : 'error';
