# Functional review

Congratulations! At this point, you've completed all [previous milestones](https://author-prod.avalara.com/editor.html/content/avalara/for-review-only/en/leila-paul/services-calculation-en/before_you_begin/planning_your_integration). 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 [partnerlaunchsupport@avalara.com](mailto:partnerlaunchsupport@avalara.com) or [talita.paes@avalara.com](talita.paes@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 Setup Avalara Credentials
    -   How to Test Authentication Connection - Health Service (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.
