You can integrate Hunter with your service or create custom connections with our API functionality.
To get started with the API, you can have a look at your API overview page, where you will also find your API secret key needed to perform any calls.
Features
Our API service includes the following features:
Domain Search
Email Finder
Email Verification
Email Count
Leads
Lead Lists
Campaigns
Request usage
When using the API, requests are counted in the same way as on the website, and the same pricing is applied.
Rate limits
When using our API, we ask that you follow our rate limits which are as follows:
The Domain Search API call is rate limited to 15 requests per second.
The Email Finder and Email Verifier API calls are both rate limited to 300 requests per minute, with bursts of 10 requests per second.
API calls in bulk
Each API call needs to be performed with one piece of data at a time (1 contact, 1 domain, 1 email, etc.). We don't currently offer "bulk" API calls.
Webhooks
Hunter supports the Webhooks integration which can be configured to be added to all your campaigns by default, or you can create a webhook linked to a specific campaign only.
Webhooks are notifications about various events that occur for your sent emails in Hunter Campaigns. These notifications can be used to integrate Hunter Campaigns with other applications.
