Pre-filled message to a Telegram number

Question

Here I found a very useful answer showing how to send a pre-filled message from a website using whatsapp.

Can we do the same with Telegram?

Answer 1

You can try to use open a Telegram chat with:

1. https://t.me/username
2. tg://resolve?domain=username

And send a message to your contact with tg://msg?text=Text&to=+(user mobile number)

But sending not works for me.

Answer 2

All of these URLs should be valid...

https://t.me/share/url?url={url}&text={text}
https://telegram.me/share/url?url={url}&text={text}
tg://msg_url?url={url}&text={text}

The official API documentation source: Core.Telegram.org: Widgets -> Sharing Button

They suggest the t.me format. You may prefill the following fields:

• url : The URL you want to share.
• text : Text to accompany the URL you want to share.

So, for instance, you might have...

https://t.me/share/url?url=http%3A%2F%2Fwww.revoltlib.com%2F&text=Revolt+Library
