I'm trying to add passwordless email signin to my Firebase app, so the first thing I did was to whitelist my domain:

whitelisted domain

Next, I tried to create the dynamic link:

enter image description here enter image description here enter image description here

At this point, when I pressed the Create button, I got the error. Anyone see what I'm doing wrong?

I also tried what was suggested in this video with the same result.

One last thing and then I've run out of ideas: In the Chrome developer console, I see the Create is failing with an error 400, suggesting that I needed to update the whitelisted URLs. I did that by adding the following URL:

enter image description here

and also enter image description here

This problem has been driving me crazy. I've tried everything, I think. Makes me wonder if I need to recreate my app in Firebase.

This issue usually means that your pattern doesn't match with your deep link URL.

So if you're trying to add https://pento-2a27b.firebaseapp.com as your deep link, you should have a whitelist pattern similar to ^https://pento-2a27b\.firebaseapp\.com

Let me know if this works.

  • Holy S**T! It worked!! Thanks a whole bunch. Now the only question is, how do I award you the 50 point bounty, since the bounty period expired? – FractalBob Oct 04 '19 at 11:18

    that's something I cannot answer. I'm so sorry.. >.< I'm here to help fellow developers and I'm more than happy enough to know that my suggested whitelist pattern worked for you. – dev.for.fun Oct 04 '19 at 12:39
  • Maybe you can upvote it yourself and at least get half credit. I tried to log in with different accounts but SO knew it was me, so I could only give one upvote. – FractalBob Oct 04 '19 at 13:06

    unfortunately, you cannot upvote your own posts/answer. maybe tag someone you knew here who works in Firebase so it gets upvoted. lol – dev.for.fun Oct 04 '19 at 13:10
  • @dev.for.fun You have also just totally made my night by rescuing me from 2 hours of complete hell! Hence the upvotes on your answer and comments! You really do deserve the bounty that the OP was trying to give you; what a shame that you saw this question too late :-( – Kenny83 Aug 31 '21 at 14:26

Firebase Auth only supports custom Firebase Dynamic Links without custom paths.

So if your custom domain is https://example.com/link, it won't work. However, configuring https://example.com as the custom domain will work. Therefore im thinking the issue is with the URL you are providing

Also take a look at this , it also displays how to create URL . Firebase says "Domain not whitelisted" for a link that is whitelisted

Give me a response of your outcome :)

  • Thanks for your suggestion, Anjula, but setting the dynamic link to https://www.example.com didn't help; in fact, I had tried that earlier. As for the suggestion about whitelisting, I had already whitelisted the link. – FractalBob Oct 02 '19 at 04:42
  • @FractalBob I think i may have found your issue , i think it is still the pattern that confuses the link to be recognized as not whitelisted. Take a look at this , https://support.google.com/firebase/answer/9021429?hl=en make sure you use the same patter for both of them – Anjula Serasinghe Oct 02 '19 at 05:21
  • Thanks again. I tried changing the whitelisted item to ^https://pentoapp\.page\.link/.*$ but that had no effect. – FractalBob Oct 03 '19 at 06:31

  1. Create Firebase dynamic link domain using app.page.link
  2. Get Your link of which you want to create dynamic link, get string pattern from Url regexator
  3. Go to setting in Firebase Dynamic Link. Add linkRegexator in whitelist pattern
  4. Create New Dynamic Link in with campaign
