# Retain

The `retain` operation stores a TrustedForm certificate in your account per your account retention setting
(defaults to 5 years). This should be performed for all certificates associated with leads you intend to contact
so that you have proof of the events that took place.

**Important:** When retaining a certificate, you must also execute the `match_lead` operation. This ensures that the lead with
which you received the certificate matches the lead data collected on the cert.

Requires a Self-Service plan or higher.
