# 400 ERR – Parameter Unknown – level3

 * I just started noticing this in the Stripe developer logs. Every transaction 
   has five different entries, including this 400 ERR. The sequence of events in
   the log for each transaction are exactly the same (in order of timing as they
   occur):
 * 200 OK – Post /v1/sources
    200 OK – Post /v1/customers 200 OK – Post /v1/payments_intents
   400 ERR – Post /v1/payment_intents/pi_xxxxxxxxxxxxxxxx/confirm 200 OK – Post /
   v1/payment_intents/pi_xxxxxxxxxxxxxxxx/confirm
 * I wasn’t sure it if was a good idea to share all the characters from the stings
   in those last two entries, hence all the x’s.
 * Every single transaction follows this sequence of events in the log. All 400 
   ERR entries have the same “received unknown parameter: level3”.
 * Please advise….

 * It was indeed a good idea not to share all the characters, so don’t worry about
   it.
 * I hope this helps! Let us know if you have any further questions.
 * Thank you.

 * As a little more information, Level3 data is BETA per Stripe support. It is a
   feature they can enable, but they don’t want to.
