This chapter provides technical information about the integration with IBAN Management Service using REST API integration model.

<p class="callout success">**Tip:** This API requires Mutual TLS authentication. You can use the same certificate for all mTLS-secured APIs exposed by Verestro. If you don't have one, follow this instruction: [Connecting to server-to-server APIs](https://developer.verestro.com/books/connecting-to-our-services/page/connecting-to-server-to-server-apis)</p>

<p class="callout info">In a server-to-server connection, the authentication of the enduser is your responsibility. Our system exclusively authenticates the Partner Instance (the partner application).</p>
