Problem
The payload for Card campaigns failed to be fetched.Explanation
For the payload to be fetched:- The card campaigns must be active.
- The campaigns must be sent out.
- The Show Card toggle must be turned on.
Example
- In the following example, there are two Card campaigns: one is active, and the other is paused.

- The sent and delivered counts for the active campaign are 0 because the campaign is not sent to anyone.

- You can fetch the payload only if the Card campaign is sent and the Show Card toggle is turned on.
