Webhook API email verification with ValidReach
Webhook routing and payload trigger utility for custom email verification pipelines. Connect Webhook API to ValidReach via REST API webhooks, workflow automation (n8n, Make, Zapier), or CSV/XLSX batch exports to verify email addresses before sending or syncing.
How it works with Webhook API
Connect via HTTPS webhooks, automation runners (n8n, Make, Zapier), or CSV/XLSX batch exports.
- 1
Add a ValidReach verification step inside Webhook API right after any trigger that collects or updates an email address.
- 2
Call POST https://validreach.dev/api/v1/verify/single with Authorization: Bearer YOUR_API_KEY.
- 3
Branch the workflow on data.status (valid, invalid, disposable, catchall, role, unknown).
- 4
Pass verified contacts to your ESP or CRM and log rejected addresses to an audit sheet or Slack channel.
When to use ValidReach with Webhook API
Three common patterns teams deploy to stop hard bounces and protect domain reputation.
Protect Webhook API sender reputation
Remove hard-bouncing and deactivated mailboxes before Webhook API dispatches newsletters, lifecycle flows, or announcements.
Real-time signup & webhook verification
Validate new addresses at capture so typos and disposable domains never enter your Webhook API audience.
Scheduled list re-verification
Audit aging Webhook API segments before seasonal campaigns using bulk CSV/XLSX verification with full column preservation.
Mapping ValidReach fields into Webhook API
Call POST /api/v1/verify/single from your webhook or workflow runner and route contacts based on the returned status.
POST https://validreach.dev/api/v1/verify/single
Authorization: Bearer YOUR_API_KEY
Content-Type: application/json
{
"email": "contact@example.com"
}validreach_status | Recommended Webhook API Action |
|---|---|
| valid | Allow into active Webhook API campaigns & flows |
| catchall / role | Tag for low-volume sending or manual review |
| unknown | 0 credits billed; retry later or require opt-in click |
| invalid / disposable | Suppress or reject before Webhook API send |

Webhook API email verification questions
- Does ValidReach require a native plugin inside Webhook API?
- No. ValidReach connects to Webhook API through standard HTTPS webhooks, our REST API (POST /api/v1/verify/single and /api/v1/verify/file), or automation runners such as n8n, Make, and Zapier—so you can inspect and control every field mapped into Webhook API.
- How should I handle catch-all or unknown results in Webhook API?
- Route confirmed valid addresses directly into active Webhook API flows, suppress invalid and disposable addresses immediately, and tag catchall or unknown records for low-volume sending or a later retry. ValidReach never charges credits for unknown results.
- Can I verify an existing Webhook API export without losing custom columns?
- Yes. Upload your Webhook API CSV or .xlsx export to /dashboard/lists or POST /api/v1/verify/file, then download results with include_original=true to keep every original Webhook API column alongside the verification status and reason code.
- What is the fastest way to automate Webhook API verification?
- Use Webhook API's built-in HTTP Request module (or the n8n-nodes-validreach community node in n8n) to call POST https://validreach.dev/api/v1/verify/single with your Bearer API key.
