Data & Infrastructure Agility


Exploring the Technical Side of Ingesting Data into Braze

By Matt D’Abreu and Maciej Olko Oct 14, 2021

Data is central to marketing today, allowing brands to power relevant, highly personalized experiences for their customers at scale on a global level. But while we’ve seen a strong focus on data collection and data privacy over the past five years, there hasn’t always been as much focus on an equally important component of the data equation—namely, data management, which refers to the ways companies control how data moves in and out of the digital systems that provide the foundations for their customer engagement programs.

At Braze, our customer engagement platform is built on a foundation of streaming data. That architecture allows our customers to gain an in-the-moment understanding of how their users engage (or don’t, as the case may be) with their messages, their website, their mobile app, and more. Having that data—and the ability to dig deeper or act on it, as the situation dictates—makes it possible for brands to build better relationships with their audience and hit their business goals.

That’s why we prioritized making it easy to surface data from the Braze platform by building our high-volume data export feature, Braze Currents, and adding support for Snowflake Secure Data Sharing. It’s also why we offer a suite of different data ingestion options for brands looking to push data into Braze to enhance their customer engagement efforts. To provide you with a richer understanding of how to pass information into the Braze platform, let’s look at the four main ways that Braze ingests data and the nuances of each approach.

1. SDKs

At Braze, software development kits (SDKs) serve as a foundational element of our customers’ data ingestion efforts, making it possible to collect detailed data about user attributes and their engagement within a given brand’s mobile app, website, connected TV app, and more into the Braze platform. SDKs can collect nuanced session data and user events in real time as consumers engage with your app/website/etc., supporting audience segmentation, the creation and delivery of campaigns and individualized customer journeys, and other elements of a best-in-class customer engagement program. (Check out the full range of Braze SDKs here.)

To take advantage of Braze SDKs to support data collection, brands need to integrate them into their app or website. Different levels of data collection will require different approaches to integration, but the baseline integration for Braze SDKs is simple and straightforward, requiring limited engineering support and having minimal impact on app/website sizes. When it comes to scaling, our SDKs are built to handle data at a massive scale, with brands using them to collect and act on information for millions of daily active users without having to worry that they’ll overburden their digital systems.

How does it work? Once the SDK has been integrated into an app or website and you’ve determined what information you want to track, it begins collecting device and session data on any individual engaging with that digital platform, even those whose identities are not known by the brand. Both these so-called “anonymous” users and “known” users (i.e. individuals who have shared their identity with the brand) will automatically have live-updating customer profiles created within Braze, allowing marketers to leverage segmentation, personalization, and triggered messages to reach even anonymous users, supporting a more tailored, meaningful brand experience across the board. Once a user does identify themselves, brands can use the data they’ve been collecting pre-identification to map that user back to any other systems they may be using, allowing them to provide a cohesive, ongoing brand experience even across different channels, platforms, and devices.

The upshot? If you want to be able to collect, manage, and take action based on user engagement with your app or website, taking the time to integrate the relevant Braze SDK makes that process simple, automatic, and highly scalable, supporting high-volume ingestion of essential customer information.

2. APIs

While SDKs are great when it comes to gathering data directly from the front end of your app or website, sometimes you may want to integrate data from other sources, such as loyalty databases or your own back end. To supplement that foundational element of their data ingestion strategy, many brands turn to application programming interfaces (APIs), which are services designed to handle and respond to requests made between different systems. In this case, they make it possible for brands to pass information from internal systems and third-party solutions into Braze in real time, complementing the automatic data collection carried out by their SDKs. Our APIs are able to flexibly accept data from almost anywhere, as long as it’s formatted correctly for transmission to Braze.

Perhaps the most common use cases we see for API-related data ingestion is when a brand is looking to upload historical data into the Braze platform. In that situation, where a company may have information they’re bringing from a previous customer engagement platform or some other relevant system, the easiest way to make that happen is by leveraging an API to do an initial transfer of user data, create user profiles, and upload users’ push tokens via the Braze platform’s API endpoints. Other use cases include:

  • Importing other user information that isn’t being tracked via your SDK into Braze. For instance, point-of-sale (POS) system information, or any other offline data that isn’t directly related to engagement with your app, website, or customer messaging.

  • Changing a given consumer’s external user ID, deleting users, or aliasing users within Braze.

While APIs can be leveraged for a wide variety of data ingestion uses (as well as other needs, such as dynamic content personalization), they are more likely to be impacted by the scale and volume of your data ingestion efforts than SDKs. For that reason, it’s important to be mindful of how many API calls are being carried out and any relevant rate limits and functional traffic limits associated with your API endpoints.

3. CSVs

While SDKs and APIs support the vast majority of potential data ingestion needs and use cases associated with the Braze platform, we do offer a third native way to transfer information into Braze—namely, the ability to upload comma-separated values files, known as CSVs. This approach tends to make the most sense when used for quick, one-off use cases or for teams that lack the technical resources to set up SDKs or leverage APIs. What does that look like in practice? One example might be collecting user emails in a Google sheet, downloading that sheet as a CSV, and then uploading it into Braze to update user profiles.

CSV uploads can be a helpful way to transfer information into Braze in a pinch, but this approach is less scalable than using APIs or SDKs to ingest data. However, there is a new way to make more effective use of the Braze CSV import function and minimize some of the scale disadvantages associated with this feature when working to upload user attributes. By taking advantage of an open source Amazon Web Services (AWS) serverless application created by the Braze Growth team and leveraging AWS Lambda and S3, Braze customers can avoid the manual splitting and uploading of large CSV files containing user attributes.

With this application, brands can upload CSV files containing user attributes (including files that are larger than 100 megabytes) to an S3 bucket, automatically triggering a communication to Lambda that leads it to leverage the application’s code, processing the CSV file, processing it, and passing it into the Braze platform. The application avoids the manual file preparation associated with large CSV file upload in Braze and makes the process more seamless and more automated; however, the process is not as frictionless as passing data into Braze via SDK or API, so brands that are able to leverage those tools to transfer user attributes into Braze are strongly encouraged to do so.
