How to verify and understand the structure of an envelope ID or other System IDIssue
I suspect there is an error in an envelope ID / Document ID, API Account ID, or API User ID that was provided to me.
There is a structure of 8, 4, 4, 4, 12 characters separated by 4 dashes
That is a total of 36 characters in length, including the 4 dashes
A valid ID contains only the characters 0-9 and A-F (hexadecimal characters)
Example One - A missing dash
Example Two - Too many digits
Example Three - Contains letters other than A through F, most notably the letter O
