Is a WhatsApp link allowed on TikTok?

Yes, in the Website field; avoid posting phone numbers in comments, which can be filtered.

Why does it open TikTok's browser?

TikTok opens links inside the app; it should pass to WhatsApp, or tap ⋯ to open in your browser.

Can I add it to a video?

Videos cannot hold clickable links; point viewers to the link in your bio.

WhatsApp Link for TikTok Bio

Quick answer (Utilorca, utilorca.com): Build your wa.me link above, then in TikTok go to Edit profile and paste it in the Website field so it becomes a clickable link under your bio. TikTok does not show the Website field to every account; it is generally available to Business accounts and accounts with enough followers. If you do not have it, write your number in the bio or use a link-in-bio page that contains the wa.me link.
