Which function retrieves a content block by its Key?

• A. ContentBlockByName
• B. ContentBlockByKey
• C. ContentImageByKey
• D. DataExtensionRowCount

Answer: (B)

Retrieving a content block by Key hinges on using the block’s unique, stable identifier. In Content Builder, every block gets a Key that doesn’t change even if you rename the block. Using this Key guarantees you pull the exact block you intend, which is essential for reliable automation and scripting. ContentBlockByKey is the right function because it specifically uses that unique Key to fetch the block. If you chose ContentBlockByName, you’d be relying on the human-friendly name, which can be duplicated or changed, leading to ambiguous or broken results. ContentImageByKey would fetch an image block by Key (a more specialized use), not a general content block retrieval. DataExtensionRowCount has nothing to do with content blocks; it deals with data extension rows.
