Who can change card limits
Admins can change the card limits for all cards.
All other users can request limit changes for their own cards which then can be approved by the responsible person.
How to change a card limit
Card limits can either be made lower or higher for less or more resources on your card.
Click on “Cards”
Select the card that you want to change the limit for
Under "Limits" > "Amounts" you can change the limit
If you aren't the card owner but an Admin, the card owner will get a message about the updated limit.
