What is the exact profile ID format? I’ve seen 01FTT1WWTB6154RJ1201VMFAJH mostly, but now JpZ5Ez? is the latter referring to a profile too?

Hi @kenw232, so I’ve seen it both and my best guess is when the underlying framework of Klaviyo upgraded/improved over the years they moved from the short version to a longer format for profiles. I suspect its to better obfuscate profile IDs (for security?) and obviously future proofing it for the number of alphanumeric combinations that can represent a unique profile.
