Saving Cookie Hash Method?

Hey,

I am receiving the cookie for first_name, phone_number, email_address which is being saving to the stape cookie (when sending the via the data tag)

I want to hash it, and wondered if the pixel in GTMserver will be ok with this hashed? Can I un-hash it when i get it in the server container?

Sorry a little new on the cookie side/

Yes, you can use hashed user data in tags. Most tags check the data for hashing and if it is already hashed send it in that form.
But note that different platforms may require different hashing formats for the data and some tags may not have hash validation, so they will hash the hash, which will cause errors on the platform you are sending the data to.

Thanks Alex, that makes sense, RE: hashing.
