# How to Configure mTLS

> Step-by-step guide to configuring Mutual TLS (mTLS) as the data transport method for accessing the Zeotap Profile API.

Perform the following steps to access Profile API using mTLS as the data transport method:

<Steps>
  <Step title="Receive Certificate from Zeotap">
    Zeotap provides a certificate and requests the **SR (Certificate Signing Request)** from you.
  </Step>

  <Step title="Sign and Return the Certificate">
    Sign the certificate and return it to Zeotap.
  </Step>

  <Step title="Zeotap Authorises the Final Certificate">
    Zeotap's **Cloudflare Manager** will authorise the final certificate by signing it, and then return it to you.
  </Step>

  <Step title="Upload the Certificate">
    Upload the final certificate in the **settings or configuration section** of your application.
  </Step>

  <Step title="Save and Access via mTLS">
    Save or apply the changes. Afterward, you can access the APIs over mTLS via the endpoint:

    ```
    https://mtls-api.zeotap.com
    ```
  </Step>
</Steps>
