Hi, is it possible to trigger sending the email verification mail through the backend sdks?

Yes it is. There should be a function to generate an email verification token and another function to send the email with that token. Which recipe are you using?

I've overwritten the sendEmail function for reset password mail and email verfication mail to send a custom mail... I was using `sendVerificationMail` on the frontend to trigger the send mail function, but I would like to trigger it in the backend within an api handler.

The usecase is: I wan't to send a email verification mail after the user has completed the other custom auth stuff (in my case, setting a username...)

```ts
let userInfo = await ThirdPartyEmailPassword.getUserById("<userId>");
if (userInfo !== undefined) {
    let resp = await ThirdPartyEmailPassword.createEmailVerificationToken(userInfo.id);
    if (resp.status === "OK") {
        let token = resp.token;
        await ThirdPartyEmailPassword.sendEmail({
            // you can use your own websiteDomain / websiteBasePath
            emailVerifyLink: `http://localhost:3000/auth/verify-email?token=${token}&rid=thirdpartyemailpassword`,
            type: "EMAIL_VERIFICATION",
            user: {
                email: userInfo.email,
                id: userInfo.id
            },
            userContext: {} // this doesn't matter
        })
    }
}
```

Alright, thanks a lot.... However, I wonder what the fronentSdk exactly does... because maybe it's more efficient to just do the same thing the `sendVerificationMail` does on the backend.

that function calls the API on the backend that sends the email verification email. You can see the logic of that API here: https://github.com/supertokens/supertokens-node/blob/master/lib/ts/recipe/emailverification/api/implementation.ts#L51

It's pretty much the same thing as the above code.

Yes will implement the above code! Thanks for the most amazing support ❤️
