So, I'm trying to link a character to his dndbeyond character. I go to Campaign>import external character and I put the character's link in, with /json at the end. It says something arcane about illegal strings. What am I doing wrong?
Can you post the link here or email it to me (info@dmhelper.net)? The only thing that really matters from the link is the ID number in the link, the DM Helper uses that to access the link specifically itself. You can try just entereding that ID number.
