# 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 do 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**

If applicable, It's important to demonstrate the electronic invoice issuance control panel, which allows the customer to consult an authorized electronic invoice, cancel an electronic invoice, perform a correction letter, and other functions that are necessary to execute the electronic invoice issuance, in compliance with the Brazilian Tax Authority.
