I am using devloper test account for testing application connected under markteplace, if I am sending sms to dummy contact message is appearing as, "Insufficient credit to send messages. Please contact your administrator. "
what should I do to fix this
Hey @SQA
HubSpot has recently updated the limits for testing in Developer Accounts
You can see a couple of them here
I believe that if you have reach the maximun
you should create a new test acount.
You also check up the Free limits in products catalog
Hope this helps
