HTTP output to parse JSON

Posted on by DaveTalbot

Hi,

I submitted a POST call and get back as below.

I add a compose line, which brings back the following

I am struggling to extract the "IdToken" element from this using parse JSON. I added an array line and then when I use Parse JSON and add the schema in which includes the IdToken, it seems to use the 'header' as content rather than the 'output' I had chosen. Can anyone help me understand what I have done wrong ?

You should be able to fetch this directly from the "Sample Object" output via ?['[IdToken]']

Thanks a lot for your reply, much appreciated. I'm relatively new to this, would I put that statement in a 2nd compose and what would it be ? I tried with the below but it came out empty so I didn't use it correctly

Try from Sample Object, not from Compose. Or directly from HTTP/body

Thanks for replying. I tried with both of the below. Am I using the correct statements for these ?

Compose
body('HTTP')?['[IdToken]']

Compose 2
outputs('Sample_Object')?['[IdToken]']

I wrote the output that contained the details I needed to a csv in the flow and then parsed the csv which produced the outputs I needed.
