Are gta online heists related to the single player story?

The Wikipedia entry for Grand Theft Auto Online describes it as the online component of Grand Theft Auto V, set in the fictional state of San Andreas, and mentions multiplayer modes, but it contains no reference to heists or any connection to the single‑player narrative. Because the evidence does not discuss heists, their structure, or their relation to the single‑player plot, we cannot confirm that they are related or unrelated. In the absence of explicit information, the safest response is that no documented link has been provided in the source. If you need definitive confirmation, additional sources would be required to examine the design of heists in GTA Online and any narrative ties to the single‑player story.
