How prefilled chat links work
The tool builds official chat URLs with encoded text, so users open the conversation with the message already prepared.
WhatsApp links require a phone number. Telegram links can use a public @username or an international phone number.
High-impact usage scenarios
Use these links in CTA buttons, social bios, paid traffic pages, CRM templates, and support signatures.
Prefilled text reduces friction and helps the user send the first message with the right context.
- Click-to-chat button on landing pages.
- Telegram support shortcut in docs and help centers.
- Campaign links with short qualification message.
- Sales triage message for inbound leads.
Practical limits and validation
WhatsApp does not support @username in wa.me format. Use full international number with country code.
For Telegram, @username links are usually more stable when available on the profile.
