Summary

Verifies whether a phone number exists on WhatsApp through the selected ZAP Gateway instance. Returns the gateway’s check result with a Chatwoot-ready phone number; the Full Fallback variant also accepts formatted input and checks number variations and profile data.

Inputs

  • Instância (required) — Select the WhatsApp instance configured in ZAP Gateway.
  • Número de Telefone (required) — Number to check. The standard check expects digits or a supported group ID; Full Fallback accepts formatted numbers such as +55 (81) 98744-9911.
  • Incluir Resposta Completa — When enabled, includes all gateway response fields and metadata. Otherwise, the output is limited to selected fields such as exists, phone, phoneChatwoot, profile, and variants when present.

Output shape

One n8n output item per input item, containing a JSON object with the phone-check result.

The operation adds phoneChatwoot in E.164 format when the number exists, or null when it does not. Available fields depend on the gateway response; enabling Incluir Resposta Completa preserves all returned fields. With Continue On Fail enabled, errors are returned in an error field.
