Does this work for international numbers?

Yes. The action supports phone numbers from any country where WhatsApp is available. Provide the number in international format with the country code (e.g., +44 for UK, +91 for India).

How many credits does it cost?

1 credit per run. You can check your remaining credits in the SyncGTM dashboard.

Can I use this action via MCP with AI tools?

Yes. Configure the SyncGTM MCP server in your AI tool (Claude, ChatGPT, Cursor, Windsurf) and you can validate WhatsApp numbers directly from your AI assistant.

Is the profile information always available?

Display name and profile picture depend on the user's WhatsApp privacy settings. If the user has restricted their profile visibility, only the has_whatsapp status will be returned.
