# Connect the Google Ad Manager (GAM) account

If you select the "Google tag for GAM competition" callback option, Nexx360 requires a connection to your Google Ad Manager (GAM) account to push SSPs orders and line items. This enables competition between your direct campaigns, Google Ad Exchange and the SSPs configured in Nexx360.

Few steps are required, see below.

## 1. Enable API Access

In your GAM account, go to *“Admin”* > *“Global settings”* > *“Network settings”* section. Enable API access (if it’s not already done) and add a service account user with the following information:

* *Email:* <gamlineitemtool@nexx360.iam.gserviceaccount.com>
* *Role:* Administrator

## 2.Add new GAM account

Send a message to [tech@nexx360.io](https://malto:tech@nexx360.io) with your Network name and Network ID (this information can be found on the top of your GAM account menu or in the "*Admin”* > *“Global settings”* > *“Network settings”* section). This step will allow the Nexx360 team to finalize the setup.

## 3. Generate SSP line items

Once the set up is finalized, line items will be generated in your GAM account with a campaign for each SSP. Then, you can locate all the created campaigns in your GAM account under “Nexx360 - Fast - SSP”.

If you have multiple GAM accounts, it's essential to repeat this process for each network.
