# Proof Verifier

The Proof Verifier should take these two steps for the integration with zkPass:

1. [Providing a REST API to retrieve the DVR](/zkpass/zkpass-developers-guide/zkpass-modules/dvr/dvr-client-roles/proof-verifier/1.-providing-dvr-retrieval-api.md)
2. [Providing a REST API to verify ZkPass Proof](/zkpass/zkpass-developers-guide/zkpass-modules/dvr/dvr-client-roles/proof-verifier/2.-providing-proof-verification-api.md)

## <mark style="color:blue;">Sample Implementation</mark>

A sample implementation for a proof verifier is provided on the zkpass-sdk repo, as shown here:
