# Collection

## Overview

Issuing SRRs under collection is similar to issuing SRRs without collection.

When issuing SRRs under collection, we add a few extra processes.

1. Create collection
   1. The Client will receive the collection address when they receive a reply about creating a collection.
   2. The client must ensure that the collection is created. This can be done in one of two ways.
      1. Check the LUW collection.
      2. Get webhook when collection creation is complete. In this way, the client must tell Startbahn to subscribe to the collection\_creation webhook.
2. Issue SRR
   1. Include the collection address in the request of issuance.
