400 Response when making API calls

  • Updated


Requests to API POST and PUT endpoints results in a 400 (Bad Request) response.


One possible cause is that the double quotes used in the JSON contained in the body of the request (which per the JSON specification should be represented by the 0x22 ASCII character) have been inadvertently replaced with the unicode characters for left and right double quotes (0x201C and 0x201D, respectively).  This has been known to occur when sharing the JSON content via chat clients such as Slack which "prettify" content.


Ensure that the double quotes as represented as ASCI 0x22.
