@juanshishido can you elaborate a little on the “improper encoding” here. I figured that it had something to do with how I was encoding my ISO 8601 timestamps (and therefore the signature) because I, like Matias, tried doing it with
YYYY-mm-dd dates, which worked. But when I do encode my query string params, I still get a 401. This makes me feel like my signing method is correct (because I can get data when date is formatted like
YYYY-mm-dd), but I’m handling the ISO 8601 case incorrectly.
