I am using sendGrid to send an email verification mail to a user, when user click on a "Verify" button it will be redirected to another link, I have successfully sent an email but I can't figure out how can I make button dynamic?
I read about substitution and don't know how to use this with button
I have added following line to my code
email.addSubstitution(VERIFY_TOKEN_KEY, new String[] { token.getToken() });
And this is my Button code on SendGrid
<a style="background-color:#51a9a4;border:1px solid #333333;border-color:#333333;border-radius:6px;border-width:1px;color:#ffffff;display:inline-block;font-family:arial,helvetica,sans-serif;font-size:16px;font-weight:normal;letter-spacing:0px;line-height:16px;padding:12px 18px 12px 18px;text-align:center;text-decoration:none;"
href="-verifyLink-" target="_blank">Verify</a>
What should I write in href?
