Hi @TheCarpoolKing! Happy to assist =)

To automatically add customers to Klaviyo and update their segments based on their actions, you can integrate your service-based business's live database with Klaviyo using its APIs. Klaviyo provides APIs for managing lists, subscribers, and events, which you can use to synchronize your customer data in real-time.

Here's a high-level overview of the steps involved:

1. Connect to Klaviyo's APIs: You'll need to obtain an API key from your Klaviyo account, which you can use to authenticate your API requests.

2. Create a List: In Klaviyo, you can create a list to store your customer information. You can create a custom list for your business needs, or you can use one of the default lists such as "All Subscribers" or "Subscribed".

3. Add Subscribers: Whenever a customer signs up, you can use Klaviyo's APIs to add them to the list. You can pass along any relevant information about the customer, such as their name, email, and any other custom fields.

4. Update Subscriber Information: As customers take actions, you can use Klaviyo's APIs to update their information and move them between segments. For example, if a customer makes a purchase, you can move them to the "Purchased" segment.

5. Track Events: Klaviyo provides APIs to track events, such as a customer making a purchase or clicking a link in an email. You can use these events to update customer information and trigger automated email flows.

By integrating your live database with Klaviyo, you can ensure that your customer information is always up-to-date and that your customers receive relevant and personalized communications.

Hi @TheCarpoolKing, 

Happy to help, it is definitely possible and beneficial to use Klaviyo even if you’re not an ecommerce company!

@Irrra saves the day and has hit the nail on the head! For a custom connection from your site to Klaviyo, to feed information about profiles, activities they take and etc, you’ll need to set this up via our APIs.

But don’t worry, our Developer portal has all the information you need to set this up and we also have a nifty developer group to ask any further questions! As this will require custom coding, I’d have your dev team set this up for you if you’re not comfortable! I can see you’ve already taken advantage or our developer group by asking a similar question in this thread below and that user helped give you ways to get started via our API! 

Thanks for participating in our Community and good luck getting this started for your Company! 

Have a great weekend, 

Taylor
