Text · preview_url

Send a text with a link preview.

Plain text up to 4,096 characters. Turn on preview_url and WhatsApp unfurls the first link into a card with its title and image.

to and the message ids are n8n expressions that read the WhatsApp Trigger right before this node ($json.messages[0].from / .id). For a manual test, replace them with a number and a message id.

The JSON body

HTTP Request → Body → JSON

  2. Only the first URL gets a preview, and it must start with http:// or https://.

  3. No preview available? WhatsApp shows a plain clickable link; preview_url is optional.

  4. Only inside the 24-hour window after the customer's last message; after that, send an approved template first.

How to set up the credential in n8n
  1. In n8n, open Credentials → Create credential and pick Header Auth.
  2. Fill in the two fields:
    NameAuthorization
    ValueBearer <your token>
  3. Open the pasted node. Authentication is already Generic → Header Auth; choose the credential you just made.
  4. Use a System User token from Meta Business settings; the token on the API Setup page expires within hours.Source (opens in a new tab)Source (opens in a new tab)

Your token lives in n8n only. I never ask for it.
