Segment makes it easy to send your data to Google Cloud PubSub (and lots of other destinations). Once you've tracked your data through our open source libraries we'll translate and route your data to Google Cloud PubSub in the format they understand. Learn more about how to use Google Cloud PubSub with Segment.
When you toggle on Google Cloud Pub/Sub in Segment, we’ll start sending your specified Segment events to Pub/Sub topics of your choice. Our Google Cloud Pub/Sub destination supports all of the Segment methods, and will send data from any one of our libraries.
In order for us to publish events to a Pub/Sub topic on your behalf, you must grant our Google Cloud Service Account publish access to your chosen topic. Please follow these steps to enable this:
- In your Google Cloud Console, navigate to your Pub/Sub topic list. You should be able to access this list here.
- Once there, either select an individial topic or multiple using the checkboxes to the left of each topic name. Once you have made a selection, you should see some Permissions options on the right of the page.
- In the Add Members input field, copy/paster Segment’s Service Account email:
- Click the Select a Role dropdown and choose Pub/Sub Publisher.
- Click Add.
You should now see our Service Account email as a Pub/Sub Publisher like this:
To begin using the Google Cloud Pub/Sub destination you must first decide on which Segment events you would like to route to which of your Pub/Sub topics. This mapping then needs to be defined in your destination settings.
track events can map based on their event name. For example, if you have an event called
User Registered, and you wanted these events to be published to a topic called
projects/my-project/topics/user-registered, you would create a row in your destination settings that looks like this:
Please ensure you use the full topic path! They are formatted like this
Any Segment event type (ie.
screen, etc.) can also be mapped. This allows you to publish all occurrences of a given Segment event type to a given Pub/Sub topic. To do this, you simply to create a row with the event type (track, identify, page, etc.) and it’s corrensponding topic:
Events can be defined insensitive to case so
Page will be equivalent to
If you would like to route all events to a topic, use an * as the event name.
The structure of a Pub/Sub message follows this structure: PubsubMessage
Our integration will publish the entire Segment event payload as a Base64 encoded string and set it as the value of the
data parameter in the Pub/Sub message payload. We will set the
publishTime to be the
timestamp of the Segment event.
We do not currently integrate with the optional
attributes parameter. If you use this functionality, please contact us.
Supported Sources and Connection Modes
To learn more about about Connection Modes and what dictates which we support, see here.
Segment offers an optional Device-based Connection Mode for Mobile data with Google Cloud PubSub. If you’d like to use those features that require client-based functionality, follow the steps above to ensure you have packaged the Google Cloud PubSub SDK with Segment’s.
Segment lets you change these destination settings via your Segment dashboard without having to touch any code.
