问题
I am trying to create Campaigns by using Sendgrid V3 API. if i use Try it out tool it shows like Error message like "authorization required" even though Authorization Bearer value(API KEY) given, if i hit the same in Postman it gives error response like "access forbidden". Is this Sendgrid API Issue or am i missing anything? and one more question here is shall we try campaign related operations by using trial account?
Note: Same API key is working fine for some other operations like List,Contact etc. This is trial account.
Awaiting for your response!
