User Sign-up with Firebase

Hi all,

I want a user sign-up form / page in my new app. Has anyone done this?

I am a bit in the dark here, and apparently there are no flow components available for this, or?

Is there a road map for upcoming components?

Any help, guides, tips etc. will be much appreciated!

Also I would like to add more information about the users in Firebase. I guess I can create a document for each user that references the users UID. Is there an easy way to mange this?

Thanks in advance!



You can do this with a HTTP request. There are no specific components for that yet.


Thanks! Would you happen to have a sample or something to get me started?


I do not as of now. If I have something in a couple of days I’ll surely post it here.

Were you able to get a sample/example, or figure this out on your own?

Here’s what I did.
Created a new data source.

Enabled POST only. Entered the information below.

Created a data variable for new records:

To my register button, added a create record flow function. Created two page variables for email and password fields and bind them to the create record flow function.

Additionally, I wanted to store user information on firestore database so once the record is created, the second create record flow records the user information. Once it is all over I redirect them to the login page.

I could also redirect them to home page without additional login but people tend to forget the passwords so I wanted to make sure they at least log in once.

I’m not sure if this is the best practice but for me it works. Of course I’m open to suggestions.



Thank you for supplying the screenshots and your steps. They worked for me and I am very grateful that you took the time to make your response. I am sure it will help a lot of others also.

I do have a follow-up question though, what is a good way to link the newly created user to details they entered into the form during registration in to the firestore database, like First Name, Last Name, Phone Number, etc.?

Hi @Atakan_Tokgoz ,
thanks a lot for sharing these steps.

Just one detail to the first screenshot:

  1. what do I need to enter for the query parameter here?

  2. and what purpose has the key in the HTTP header?

figured out the answer for question 1 myself:
according to the Firebase Docs it require the API_KEY to the project.
Firebase Auth REST API

The API_KEY is found in the project settings (look for Web API key):

For question 2 I just entered the text exaclty like in Atakan’s screenshots. Don’t know what it is for, but works :slight_smile:

@Robert_Doodles, once I receive the response from the register request, I initiate the second post request as shown in my previous flow screenshot. For the other form values, I created page variables for all of them and set them to the values, but I think creating one data variable is a better choice (which I will fix on my part). I also use the flow output value for authorization uid into my user identity database.

I use firestore database and created the firestore data source in AppGyver. I don’t have anything fancy:

What I really would like to do is mapping the UID from auth and the document ID. It should be possible for rest API data source but I don’t think it is currently possible for firestore data sources. Perhaps @Mari could provide an answer there.

Glad that you’ve solved the question yourself! Yes, the key value is your web API key from your project.

For your other question;

Content-Type means how my HTTP request body should be structured on the receiving end.

Content-Type: application/json means that my HTTP request will be JSON. This was a requirement from the Firebase Auth REST API documentation as well.


I also am working on trying to figure this out, If I do I will let you know.

I am also trying to solve this problem.

For some reason, the second create record (for other user-related info like name, etc.) keeps failing. I think it may be due to the rules in Firebase which are: allow read, write: if request.auth != null;

Do you have this rule? Or do you allow writes without auth?

After changing my security rules I also started receiving authorization errors. I added the email authentication flow between the two requests. So once registration is successful, I use the same email&password parameters to authenticate the user, then start the second record creation.


This worked great! Thank you.

Could you explain this last photo? I’m not able to find some of the flow functions.

You need to download additional flows from marketplace. Open Flows, click search and write “fire” in the marketplace. You should see all the firebase related flows.

Hi there, regarding mapping Doc ID and User there is a workaround where you can create a specific Doc ID (ie UserUid) and therefore have a ref like this. That way you are just fine with calling Get record (as that require doc id) instead of collection.

Hope that makes any sense. You can check my previous posts, where I already tried to explain that.

I must state the pleasant surprise reading “Aramıza Hoş Geldiniz” in your screen-grab (Confessing that I had not read your name fore-hand)…
Çok sağol Atakan! Harikasın!

For reasons I could not understand: after I change privacy settings: I always got an error on some phones while none in others. Oddly… this solved much: THANK you.

My Question:
What exactly do you refer to as you mention “creating one data variable”?
Do you mean that it is to be set up WHILST signing up?

If so: HOW?
Are you able to customize firebase user data?
What happens then? Do you also provide “user based” authorities fireBase based (Tongue-Twister :slight_smile: )? Or would you personally advise to keep it locally with simple if functions?

To better explain my point (More-what my plans):
An administrative user capable of adding/removing authority sort of checking your “HasClub” on/off… That is cool… And what I want… But would be VERY cool is that the administratively authorized user actually fills in users on his own… from the app (Just like he can add users from fireBase itself). And to date I thought it to be impossible/not permitted. But your mentioning “one data variable” got my hopes up and I couldn’t help but burden you with more replies through which you have to date been so helpful with.

Would you please be kind enough to link us to it? Had you meant THIS one?

As I understand: you are actually answering the question I am asking… But I failed to take it home as of yet.
