Familiarity with InputContactMessageContent in the Telegram Bot API
Hello! Today we want to talk about one interesting concept in the Telegram Bot API. The name of this concept is InputContactMessageContent. This capability offers bots the ability to send information related to a contact. In general, if you have a Telegram bot and want to introduce a contact to users, this capability will be highly useful.
Imagine that you have a service bot and want to show the contact number to users. Instead of users manually entering their number, you can use InputContactMessageContent to send a contact in a proper way along with all the necessary information. This task provides users a more comfortable experience and also reduces input errors.
Using this capability is relatively easy. You need to format the contact information such as name, phone number, and... in a specific structure. Then send this information to your bot to be sent as a message. In this way, whenever the user clicks the contact button, they can directly use that contact number. This capability is especially useful for business and service bots.
In addition, we will review an example code of how to use InputContactMessageContent. This code includes an example message that sends contact information to the user. In the code below, you will see all the necessary steps to create and send this message.
Example Code
{
"chat_id": "@my_channel",
"reply_markup": {
"inline_keyboard": [[
{
"text": "Contact Us",
"callback_data": "contact"
}
]]
},
"text": "Contact us on Telegram",
"reply_to_message_id": 123,
"content": {
"type": "contact",
"first_name": "Ali",
"last_name": "Mohammadi",
"phone_number": "09121234567"
}
}Code Descriptions
