Apply a use case later

In this type of setup, you complete each part of the connection at different times. This can be useful when you are ready to link a data source, but you are not ready to set up your use case–for example, you aren’t ready to create a customer list.

Consider the following scenario:

• Step 1: Dana is an engineer who manages data for your company. Dana sets up the data source to be used for activation in Google Ads. The data source is ready to be associated with a use case.
• Step 2: Mahan is a media specialist who needs to measure audience activation. Mahan creates a customer list and then associates it to the data source that Dana has previously set up, to use that data for Customer Match.

Step 1. Initiate the connection to the data source

Set up a data source and create a connection to be associated with a use case later.

1. In Google Ads, click Tools > Data manager > + Connect Product.
2. Under Data source, search and select a data source from the list of products.
3. If prompted, select Direct connection.
4. Select your use case, read and accept the customer data policy, then click Continue. If you select Audiences, you are prompted to select the data type at this step.
5. Enter your data source location and credentials*, then click Next.
6. To map fields, select the data source fields from the dropdown lists that match the destination fields.
7. Optional: Apply transformations to your data.
8. Click Next.
9. Enter a name for this connection.
10. Optional: Edit connection details.
11. Click Finish.
12. Optional: Depending on the use case, you may add an audience segment or conversion action to your connection.
    To do this, select a connection from one of your Connected products and under Usage, click + Add audience segment or + Add conversion action. Learn more about audience segments and how to Create a conversion.

Note: If you already completed the instructions for initiating the data source connection, including the optional step, you can skip the remaining instructions for completing the connection.

* Use the same credentials and location details for this data source as described in the first part of this article.

Step 2. Complete the connection by applying a use case

1. Open the destination you intend to use–for example, begin to create a new customer list or conversion action using the steps from the previous sections. Return to these steps before completing the data source step.
2. Under Data source, select Select an existing source.
3. Select the data source that was initiated in Step 1 from the list of data sources.
4. Continue to follow the remaining steps for your use case in the first part of this article. Note that you will skip further data source-related steps, such as entering credentials, because you completed these previously.
