The Templates API is used for interacting with email templates stored in Klaviyo. This API is organized around REST. The API endpoints were designed to be predictable and resource-oriented and use HTTP response codes to indicate API errors. JSON is returned in all responses from the API, including errors.
We are working on adding the Email Templates API to our existing libraries. If you want to be notified when those libraries have been updated you can watch the following repositories:
Python (https://github.com/klaviyo/python-klaviyo)
Ruby (https://github.com/klaviyo/ruby-klaviyo)
PHP (https://github.com/klaviyo/php-klaviyo)
https://a.klaviyo.com
You authenticate to the Email Templates API by providing one of your private API keys as part of each request. You can manage your private API keys from your account. We allow you to have multiple API keys at once in case you need more than one.
Authentication happens via the api_key parameter in each request. It can be sent as part of the GET or POST parameters.
Klaviyo's API is served over HTTPS and all requests must be authenticated.
To view your API key, you need to log in.
Our API uses conventional HTTP response codes to indicate success or failure of an API request. In general, codes in the 2xx range indicate success, codes in the 4xx range indicate an error from information provided as part of the request (e.g. the requested object doesn't exist, an invalid setting, etc.), and codes in the 5xx range indicate an error on Klaviyo's end.
The response of all API errors contain a message parameter which has developer-facing information about why the request failed.
When we make backwards incompatible changes to the API, we release new API versions, which are reflected in the API endpoints. The current version, v1, is the first version. In the future, if we switch to v2, we will provide documentation on the changes as well as new documentation detailing how to use the new API.
Email template objects allow you to render and send dynamic emails based on templates you've created with the email template builder. You can also retrieve a list of email templates in your account.
