I just want to make sure that when I send pii like first last name, email address, gender so on and so forth that this does not violate meta terms of service for sending personal information. I guess another angle at this is does this get hashed like it would if you sent it via the Facebook pixel in Google tag manager for example?

Hi 
I’ve checked on this internally and can confirm that you would not be violating Meta’s terms of service by sending personal information using the Facebook Offline Conversions app’s Send Offline Event action. The personal information is hashed using SHA256 as per Meta’s API requirements.
Hope that helps to clarify things. If you have any further questions or if there’s anything else the Community here can help with just let us know! 
Thank you so much
You are most welcome 
Seems like you’re all set for now but do reach out in the Community again if you need help or clarification on anything else at all. In the meantime, happy Zapping! 
Just wanted to follow up here to note that Meta will be deprecating their Offline Conversions API in May 2025. This means that any Zaps using the Facebook Offline Conversions app will no longer work. It’s advised that the Send Purchase Event or Send Other Event actions on the Facebook Conversions or Facebook Conversions (for Business admins) are used instead.
You can find out more about this here: Changes impacting Facebook Offline Conversions users. And if you run into any issues with those action you can let the Community know here or reach out to our Support team directly and we’ll be happy to assist.
