# Copy button

Copy button block is needed to provide the user with the referral link, coupon code, etc.

The example of copy button usage to copy invite link. This is needed for users which want to send invite link to WhatsApp or another messenger instead of Telegram:

<figure><img src="/files/pb6n8U6TWzpK0K8zToDb" alt=""><figcaption></figcaption></figure>

In this case, the text for copying is:

`Get 5,500 coins from me for starting in this game. We are agents deploying AI bots into Telegram communities to take over the world. Join our forces ⚡️ {{invitation_link}}`

Keep in mind, that here the [placeholder is used](/tgtaps-docs/features/placeholders.md). `{{invitation_link}}` is a link with referral code to track your friends sign-ups.
