# Passing conversion PII data to traffic sources

Some of our integrations allow for passing of private identifying information (PII) onward to traffic sources, such as email, phone etc.

Passing this data is easy -- simple add one of our supported parameters to your postback or JS conversion tracking.

For postbacks, the current available parameters are `pii_email`, `pii_phone`.

We will add more in the future.

So an example postback can be:

.../pb?hit=xxx&rev=1.23&pii_email=hashed_value&pii_phone=hashed_value

Our system will detect and append this PII data to outgoing postbacks including those going to our integrations.

Our integrations will automatically detect if the value is hashed already. If not, we will hash them appropriately for the traffic source API.

We do not store this data in our analytics DB, though they will temporarily be present in logs.
