When Klaviyo and Gmail operate independently, marketing teams often encounter significant delays in communication. For instance, when a new subscriber is added to Klaviyo, the information may not be reflected in Gmail, leading to missed opportunities for timely email campaigns. This results in marketing personnel manually cross-referencing subscriber lists, which is time-consuming and prone to human error, ultimately wasting valuable resources that could be better utilized in strategic planning.

How to Build the Klaviyo → Gmail Sync

In Klaviyo, set up a Standard Webhook by navigating to the 'Webhooks' section and creating a new webhook that listens for the 'Subscribe' event.
Configure the webhook to send a POST request to your server endpoint, e.g., https://your-server.com/klaviyo-webhook, with the payload containing subscriber details such as email, first name, and last name.
On your server, implement a listener for the webhook that extracts the relevant data from the incoming payload.
Using the extracted data, construct a POST request to the Gmail REST API endpoint for creating a new contact: https://people.googleapis.com/v1/people:createContact.
Ensure that the POST request to Gmail includes the necessary JSON body with the subscriber's email and name in the format: { "emailAddresses": [{ "value": "subscriber@example.com" }], "names": [{ "givenName": "First", "familyName": "Last" }] }.
Test the entire flow by adding a new subscriber in Klaviyo and verifying that the contact appears in Gmail as expected.

Developer Warnings & API Gotchas

Ensure that the email field in Klaviyo is mapped correctly to the Gmail API; discrepancies in field names can lead to failed API requests.
Be cautious of the data format for names; Gmail requires both 'givenName' and 'familyName' to be present, or the contact creation will fail.
When handling the webhook payload, validate the incoming data to prevent null or undefined values from being sent to the Gmail API, which can cause errors in contact creation.
