Extracting only specific members from a Ruby hash

I would like to extract only the team_member_id and display_name from the below hash returned from dropbox api.

{"members"=>[{"profile"=>{"team_member_id"=>"dbmid:AACHnGyTHHna44224Ad-vVewFDJ9nzS7be9GJ6Tc", "account_id"=>"dbid:AAD234234234x2yGXHsG3guC04Fp8QPwUF9NDO55w", "email"=>"[email protected]", "email_verified"=>true, "secondary_emails"=>[], "status"=>{".tag"=>"active"}, "name"=>{"given_name"=>"firstname", "surname"=>"lastname", "familiar_name"=>"first", "display_name"=>"firstname lastname", "abbreviated_name"=>"MM"}, "membership_type"=>{".tag"=>"full"}, "joined_on"=>"2017-01-02T20:58:20Z", "groups"=>["g:6fe6b5a111cfc0400000000000000005", "g:6fe6b5a111cfc04000000000000015a1", "g:6fe6b5a111cfc0400000000000002299", "g:6fe6b5a111cfc04000000000000043cb", "g:6fe6b5a111cfc0400000000000056eb3", "g:6fe6b5a111cfc0400000000000058122", "g:6fe6b5a111cfc0400000000000058248", "g:6fe6b5a111cfc04000000000002dd0d9", "g:6fe6b5a111cfc04000000000002dd650"], "member_folder_id"=>"1384307556"}, "role"=>{".tag"=>"team_admin"}}], "cursor"=>"AAAXuLKhvS_T97ZjALBH4A2MCQW_xOp9bu0tAwqGuY1zBg_C-UKVZoBDTQkhU4Hok8nGT15IHN64ZE-88-dlT3242341WD8RgPBg5zfIOQqAdgJlc-Aw", "has_more"=>true}

I tried using the below code and returned nil.

puts hash['profile']['team_member_id']

What is the recommended way to extract individual data from the above hash.

hash["members"] returns an array, so you would have to do:

hash["members"][0]["profile"]["team_member_id"]
hash["members"][0]["profile"]["name"]["display_name"]

You could also take advantage of the method called dig which works on both hash and array. The advantage with this one is that it returns nil if any key is not found:

hash.dig('members', 0, 'profile', 'team_member_id')
hash.dig('members', 0, 'profile', 'name', 'display_name')
