Error using Trello API to create a board

I’m trying to create a board using Trello Rest API, however it’s giving me an error, which is weird because I’m using a name acceptable according to the API documentation.

@claragerman Try eliminating all spaces in the request. Maybe it’s just bad font kerning, but I think I see a space after the name parameter. And for testing, remove the space in the board name, as well (even though I’m fairly certain that Postman is encoding with a %20… just to be sure).
