These are three of the four configuration parameters that are required for the new Nest Integration. Next up we need to create a Pub/Sub subscriber to follow the SDM API Event. Follow the steps for this in the next paragraph.

Create a Pub/Sub subcriber for SDM

We already enabled Events previously. Now we need to enable the Pub/Sub API and create a Pub/Sub subscription. To do this follow the steps below:

1. Enable the Cloud Pub/Sub API using this link. This is easy just click on Enable.
2. From the Google Cloud Platform console we are going to create a Pub/Sub subscription. Here is a direct link.
3. Now within the Google Cloud Platform console, click on CREATE SUBSCRIPTION.
4. Enter the following settings:
   – Subscription ID: I used the same name as my project.
   – Subscription topic: select enter manually and enter the topic from the Device Access Registration console. You can get the topic by going into the project and copy the Pub/Sub topic. As shown below.
   
   
   – Select Pull as a subscription type.
   – Leave the rest default and click on CREATE.
   
   
   
   
   It is ok if you see that the integration is not tested and approved by Google. Click on Next.
5. Next you will see two more screens asking for permission. Allow those permissions.

      This is what the unacked message count should look like. If you see a high number here, please go through the steps once again.
