The single/check endpoint can be used as a webhook by adding the properties to the end of URI as a query string. This lets you easily add verification to your CRM and existing tools without any complex programming or development time.

To create a webhook follow this link. Once you've created the webhook you'll be giving a URL that looks something like the one below:{email}{email}&address_info=1{email}&credits_info=1

In order to use this webhook simply replace the {email} placeholder with the email you want to verify. Because this is the same endpoint as described in the previous section you can still use the address_info and credits_info parameters here as well.


Webhooks are not safe to use in client-side scripts (e.g. jQuery, Javascript). The URL contains a sensitive API key that should be treated just like a regular API key.
