Trying to send a datetime value to fibery via the api but get the following error response:

> Invalid format: "2024-07-16T17:02.030Z" is malformed at "T17:02.030Z"

Here’s the value I’m sending:

> 2024-07-16T17:02.030Z

Could someone help me understand what I’m doing wrong? All the documentation says UTC is the format Fibery accepts?

Try it with no seconds - e.g. `2024-07-16T17:02Z`  
or like this with no ms: `2022-01-01T08:00:00Z`

Thanks, but still getting the same error for both. ☹

"Invalid format: "2024-07-16T17:18Z" is malformed at "T17:18Z"  
“Invalid format: "2024-07-16T17:00:00Z" is malformed at "T17:00:00Z”

Finally figured it out, if anyone else ever needs help with this!

YYYY-MM-DD **T** HH:MM:SS.mmm **Z**  
also known as  
YEAR-MONTH-DAY **T** :HOUR:MINUTE:SECOND:MILLISECOND **Z**

Example:  
2024-07-16T17:15:37.561Z
