How to Create a Contact Form using Telegram Bot API

Hello! Welcome to Luxury UI

As we know, Blogger Contact Form API was updated recently and now it requires a token each an every time to successfully submit the form, that means you need to add Contact Form Widget through Layout which results in slow page loading due to blogger widgets javascripts, which we were using in only the form page earlier. Most of Bloggers use Telegram, so I have come up with a new post titled How to Create a Contact Form using Telegram Bot API.

Today, I will share codes which will allow you to receive the form submissions directly to your Telegram Group. You can also add extra fields in this form, i.e. Mobile Number, Website or anything, which was not possible in Blogger Contact Form.

This is an educational tutorial. Please consider using it for good intension.

Before we start let's take a look at its Demo.

Requirements

  1. A telegram bot, if you don't have, you can read documentation here. Bot API token is required.
  2. A Telegram Group's ID, for that create a private group, login to Telegram Web, open the group you will get Group ID in url, i.e. -1200190470, add 100 just after - sign and before 1200190470, now the chat id will be -1001200190470 just note it. Don't forget to add the bot in your group.

It is not recommended to use a supergroup, as anyone having the groupname can easily join and read your visitors' submissions.

Limitations

  1. User cannot send messages containing more than 3000 chars as Telegram has a limit when sending message of more than 4096 chars. To make sure all the submissions are successful, we have to set a limit of less than 4096 chars that is 3000 chars.

How to Create a Contact Form?

Step 1: First of all Login to your Blogger Dashboard.

Step 2: On Blogger Dashboard, click Pages.

Step 3: Either create a new page by clicking on icon or click on the existing page to add codes there.

Step 4: Switch to HTML view.

Step 5: Paste the following codes in it and Publish your page.

Replace the marked parts with correct informations.

It is not at all safe to make your Bot API Token publicly available. Use any javascript obfuscator to obfuscate the Forms Configuration codes after making all the changes. You can revoke and generate new API Token of your bot through Bot Father at any time you think something is going wrong with the bot token.

Conclusion

This is all about making a Contact Form using Telegram Bot API. I hope you enjoy this article. Please do share this article. And if you are facing problem in any section or you have any question then ask us in .
