Apollo
This page describes how to use Census with Apollo.
In this guide, we will show you how to connect Apollo to Census and create your first sync.
- Have the proper credentials to access your data source. See our docs for each supported data source for further information:
Apollo lets you create a number of API keys, each with their own set of permissions. You'll almost certainly want to create a new API key for Census rather than reusing an existing one.
In Apollo's top navigation bar, click Enrich > API Enrichment.
Then, inside API Management, click API Keys.
Next, click Create New Key.

Provide a name you'll recognize ("Census" is a good choice) and select the Set as Master Key.
Click Create API Key.
Finally, copy the code you see under API Key. We'll use that in a minute.

Great! Now let's pull it all together.
- 1.
- 2.You can provide whatever name you like for the connection
- 3.Paste your Apollo API Key
- 4.Click Connect

Census will test your API key and show a green checkmark when successful.

Once you have created your model, click Save Model.
In the "What data do you want to sync?" section

- For the Source, select the model you created in step 4
Next up is the "Where do you want to sync data to?" section
- Pick Apollo as the Connection
- For Object, pick the one you want to sync data to: Account or Contact
For the " How do you want to update the destination?" section
