Can't Post data containing $ in a key to Firebase

Question

I\'m attempting to post some data into Firebase (relative part of the URL is /messages.json). The following request content:

{\"gsx$enddate\":\"sometime\"}
<         


        

Answer 1

It's supposed to be a valid JSON but it seems like it's a limitation for FireBase

From FireBase Documentation:

Character Set Limitations

Note that URLs used to construct Firebase references may contain any unicode characters except:

• . (period)
• $ (dollar sign)
• [ (left square bracket)
• ] (right square bracket)
• # (hash or pound sign)
• / (forward slash)
