How to Retrieve list of attributes from multiple Firebase nodes

Question

My firebase DB looks like

Now I want to query the database such that I take all the users whose email id is in a query list.

For example in the above shown database structure, if I want to make a query such that find the users where username in ["allen20252482", "arne19712450"] which can give me two users.

Is it possible?

Currently I can query like https://xyz.firebaseio.com/users.json to get the complete user node data , But is it possible to filter like where I take only those users whose username is in the given query list?

I am using REST API endpoint to query the Firebase DB.

Any suggestion is very much appreciated

I suggest reading the documentation on filtering data. It sounds like you want to filter by a child key:

https://xyz.firebaseio.com/users.json?orderBy="username"&equalTo="abcdef"

You will only be able to specify one username at a time.

yes I know that I can do that query , but my question is if it is possible to query with list as params – Achy97 Apr 16 '20 at 18:21
for example I need users whose username belongs to a list ["u1", "u2", "u2"] so its not possible? – Achy97 Apr 16 '20 at 18:22
As I said in my answer: "You will only be able to specify one username at a time" – Doug Stevenson Apr 16 '20 at 19:10
