Question

Hey I have a dataset uploaded in the following form:

SomeKey

 -> Alphabet

       -a: "['apple', 'ant']"
       -b: "['ball', 'bat']"

Now using Rest API, I want to add new children to the object ‘Alphabet’. Now if I use POST it inserts a new random key as a child to Alphabet and PUT at https://gamma.firebase.com/SomeKey overwrites the current data completely. How to insert a new child using the REST API?

Answer 1

You can address the children directly by URL.

If you wrote “a” and “b” originally to:
/SomeKey/Alphabet

And then wanted to add “c” later, you can just send a PUT request to:
/SomeKey/Alphabet/c
