I was using SFMC REST API (https://developer.salesforce.com/docs/atlas.en-us.noversion.mc-apis.meta/mc-apis/postEvent.htm) for firing an event to my journey. I just noticed that there was a few error records happened.


{"message":"Value for attribute(s) exceeds max length","errorcode":30000,"documentation":""}


E-Mail: [email protected], 
ID: x, 
FName: xxxxxxx, 
LName: xxxxxxx, 
Mobile: xxxxxxxxxx, 
ID-Card: xxxxxxxxxxxxx, 
Grade: xxxx, 
Color: xxxxxxxx/ xxxxxxxxxxx, 
DealerName: xxxxx xxxxxxxxxxxxxx 1995  xxxxxxxxxx xxxx, 
Logo: xxxxxx, 
RegisterCode: xxxxxxxx

Is there a limit length of sending REST API? Where do I find this specific detail? How do I fix this error?

I found the problem. Just add maximum length of a field in Data Extension
