  2. Add ProWebLook after your Zap trigger

    Trigger your Zap from Typeform, Meta Lead Ads, Calendly, HubSpot, or Webhooks by Zapier, then add a ProWebLook action step.

  3. Authenticate once with zero credit cost

    Paste your API key into Zapier’s password-protected connection prompt. Zapier runs Get Credit Balance to verify your key and display your account email.

  4. Gate downstream CRM steps with Filter or Paths

Email Verification API

Validate Phone Number

Up to 1 phone credit per check

Standardizes national or international phone inputs into E.164 format and exposes carrier and Mobile, Landline, or VoIP line type.

Frequently asked questions

How does ProWebLook protect my API key inside shared Zapier workspaces?

Your API key is transmitted exclusively in the Authorization Bearer header over HTTPS, and Get Credit Balance returns your normalized account_email so Zapier labels the connection cleanly without showing your secret key.

What happens if Zapier Autoreplay retries a timed-out task?

Rate-limit responses (HTTP 429 ThrottledError) occur before any provider call and do not spend credits. However, if a 5xx or network timeout happens after upstream dispatch, replaying the Zap step may run a new paid lookup. Check Get Credit Balance before mass-replaying tasks.

Does Check WhatsApp Registration accept local numbers without a + prefix?

Check WhatsApp Registration requires an international phone string starting with + and the country calling code (such as +14155552671). If your trigger provides local numbers, run Validate Phone Number with a two-letter Country Code first and map its details.formatted_number output.

Do catch-all email domains return deliverable or unknown?

Catch-all domains return verdict: unknown because an accept-all mail server cannot prove an individual mailbox exists. Route unknown verdicts to manual review or secondary channels rather than high-risk cold outreach.

What is the per-minute request limit on Zapier?

The Zapier adapter allows 60 requests per fixed minute per enabled ProWebLook account in an isolated zapier-rate bucket, separate from your n8n, Make, and Chrome limits.
