Is there a way to send the verification email with the Firebase Admin SDK from my Node.js server?

Question

Is there a way to send the email verification email from my server ?

This is how it's done on the client:

authData.sendEmailVerification().then(function() {

Is there a way to do it on the server ?

@FrankvanPuffelen Similar indeed although I think it's important to point out that my issue is with Email verification, the other gentleman's issue being with Phone authentication. – Datha

Whoops, good point. Given that we just launched phone auth, I tend to over-interpret things as that. :-) – Alumina

@FrankvanPuffelen ^^ Regardless, Gio from Firebase Support told me there was currently no way to send the verification email from the server. Is this a feature that's on Firebase's radar or not at all ? I already ended up reworking my code to to send the email using the firebase client SDK, but I am still curious :-) – Datha

I just checked all the docs, because I fully expected to be able to send those verification messages from the Admin SDK. But indeed: it doesn't seem to be there. I'd recommend you file a feature request. – Alumina

@FrankvanPuffelen Done ^^ – Datha

Answer 1

To my surprise there currently is no option to send verification email from within the Admin SDK. I'd recommend you file a feature request.

What you can do from the Admin SDK is update a user profile to mark their email as verified. This allows you to take control of the entire verification flow if you want to, finishing with a call to admin.auth().updateUser(...) (on Node.js, see the link for other supported languages).

Hi, was this added in the end ? – Datha

I cannot find evidence that it was added, and the more I thought about the problem, the more it made sense to keep this client-side, and the more my server-side admin approach seemed unnecessary. Re-sending of verification emails should really be handled by an error / button generated client-side when authentication is checked client-side. – Jun

Answer 2

I just came across the same problem as you. There is a function to generate the verification link using user's email address.

I used this function on an array of email addresses, then load the result to my mail automation API to send mails out. This function is weirdly not documented:

admin.auth().generateEmailVerificationLink([EMAIL_ADDRESS])

Answer 3

You can use :

axios.post('https://identitytoolkit.googleapis.com/v1/accounts:sendOobCode?key=[API_KEY]',
    { requestType: 'VERIFY_EMAIL', idToken: response.data.idToken }
)
