To authenticate, use your GHL Contacts API key and include it in the Authorization header as a Bearer token. The key controls the contacts.readonly scope.
Authenticate Veriphone requests with your Veriphone API key. Include it as a Bearer token in the Authorization header or as Veriphone-Api-Key for added security.

When a new contact is created in GoHighLevel, Veriphone immediately validates the phone number.
Mark as verified, update verification_status, and enrich the profile with a risk score.
GET /contacts/:contactId
phone, contactId, name
On bulk import or list sync, Veriphone can verify all numbers in the batch.
Process batch, annotate results, notify on errors.
POST /contacts/
list of contacts in payload, including phone and name
When a contact is updated, re-verify critical fields.
Revalidate phone, refresh verification_status
PUT /contacts/:contactId
contactId, phone, name
Set up takes minutes—no coding required; use built-in endpoints.
Improve data quality and deliver better segmentation with verified data.
Automations and workflows can trigger verifications without custom development.
Learn the core concepts behind API authentication, endpoints, requests, and responses used in this integration.
Application Programming Interface: a set of rules that enables applications to talk to each other.
A call made to an API endpoint to fetch or modify data.
A specific URL path that performs a defined operation.
The data sent in a request, usually in JSON format.
Automatically verify phone numbers when new leads enter GoHighLevel to improve deliverability and reduce churn.
Append verification results and risk scores to contact profiles for smarter segmentation.
Run nightly batch checks on contact lists to maintain clean data.
Sign up for Veriphone and GHL, generate your API keys, and set access scopes.
Add the keys to your app, set headers, and test with curl or Postman.
Use a sandbox or staging environment to validate all flows before going live.
Veriphone can verify phone numbers, detect invalid or disconnected numbers, and provide a verification score. It can also flag high-risk numbers for manual review. The results are returned in the API response and can be saved to your Contacts records.
No heavy coding is required. Use standard REST calls and webhooks. If you can make HTTP requests, you can connect Veriphone with the Contacts API.
Rate limits depend on your plan. Start with a low rate and increase as you scale. Cache results where possible.
Errors are returned with standard HTTP status codes and an error object. Check status, message, and code to diagnose.
Yes. Use batch endpoints to verify multiple contacts in a single job and update records in one pass.
Real-time verification is supported for individual lookups and can be integrated into live forms and lead captures.
Verification results appear in the API response and can be surfaced in your GoHighLevel dashboards or stored in contact fields.
Due to high volume, we will be upgrading our server soon!
