Create a Telegram bot using @BotFather
Get your bot token
Find your chat ID using one of these methods:

Method 1 - Using getUpdates API: Send a message to your bot (e.g., /start), then call:
https://api.telegram.org/bot{your_bot_token}/getUpdates
Look for the "chat" object in the JSON response and find the "id" field. Note: Group chat IDs are typically negative numbers.
Method 2 - Using helper bots: Add @userinfobot, @ShowJsonBot, or @getidsbot to your chat - they will display the chat ID automatically
Method 3 - For groups: Add your bot to the group, send a message, then use getUpdates API to retrieve the group chat ID

Add the bot token and chat IDs in the form settings
Enable "Send to Telegram" option

How do I integrate with Google Sheets?

Can I use this with custom themes?
Yes! The plugin is designed to work with any WordPress theme. Forms are displayed using shortcodes and can be styled with CSS.
Is the plugin secure?
Yes, the plugin includes comprehensive security measures:
* Input validation and sanitization
* Nonce verification
* Capability checks
* Rate limiting protection
* SQL injection prevention
Can I submit forms via AJAX?
Yes! The plugin provides REST API endpoints for AJAX form submissions. Check the REST API section for details.
Can I use custom forms from my theme without configuring fields?
Yes! Enable "Accept any fields from frontend" in form settings (Advanced Settings section). This allows submitting any field names without defining them in Fields Configuration - perfect for custom forms where you control the HTML. All fields are still sanitized, but type validation is skipped. You can also use the mksddn_fh_allowed_fields filter in your theme's functions.php to dynamically allow specific fields or all fields (return ['*']).
Can I redirect users after form submission?
Yes! Configure a redirect URL in form settings (Display tab). You can use:
* Absolute URLs (same domain only for security)
* Relative paths (e.g., /thank-you)
External domains are blocked by default for security. To allow external redirects, use the mksddn_fh_allowed_redirect_hosts filter to whitelist specific domains.
