As you may observe, there are actually definitely only 3 steps to making use of the public library:

  • Import the public library.
  • Create a ‘Verifier’ item by giving it your API key that you generated when you signed up for the API company.
  • Run the ‘verify’ procedure, passing in the email handle you would like to verify, as well as a callback function. This callback function is what are going to be run when the confirmation has actually completed.

The records that’ s came back in the callback will definitely look something enjoy this:

Eachreturned JSON value relates different kinds of proof:

    Behind the scenes, the API service is handling all these sorts of confirmation checks for you in a lot of interesting techniques. I’ ll cover this in a potential article.
