# Functional review

Congratulations! At this point, you've completed all previous milestones. If you're a technology partner, you're now ready for your integration to be reviewed.

#### How to submit

To initiate a functional review:

1.  Create a recording demonstrating your integration, including the installation.
2.  Send the recording to [dg-partnerlaunch@avalara.com](mailto:dg-partnerlaunch@avalara.com). 
3.  Avalara will review your demo and then follow up with you. During this follow-up, Avalara will either request more information from you or inform you that you have achieved certification.

#### What to include in your demo

Your integration should include all requirements mentioned in the previous chapters. Specifically, we want to see the following:

-   How you install or enable your integration
    -   Architecture diagram 
-   Configuration screen and authentication process
    -   How to set up Avalara credentials
    -   How to test authentication connection using the Health Service API (PING)
    -   How to enable/disable service utilization
    -   Where and how to access logs
    -   Demonstrate the configurations between Sandbox and Production environments
-   Send us the payloads for each of the transaction scenarios you want to have certified
-   Additional considerations
    -   It is important to demonstrate a calculation transaction request during the demo recording session, simulating an end-user.
