# Outdated API Version?

 * Received an email from Klaviyo saying our website is using outdated API endpoints.
   From searching through the plugin code it appears to be the official Klaviyo 
   plugin using v1
   Is this the case? If yes, are there plans to update it before
   the deadline?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Foutdated-api-version%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi there – Please check your Klaviyo plugin version and make sure you are using
   version 3.3.0 or higher. All of those versions should support our new APIs.
 * You can follow this to upgrade your plugin: [https://help.klaviyo.com/hc/en-us/articles/4418005597723](https://help.klaviyo.com/hc/en-us/articles/4418005597723)

 * Thanks for the quick reply. We are already using 3.3.5. So I assume it’s automatically
   sending requests via the correct API? We don’t need to configure it in anyway?

 * Yes – 3.3.5 should definitely be all set. If you aren’t on a free plan, would
   you mind creating a ticket with our support team asking them to take a look at
   your account and confirm that you don’t need to do anything? I have a feeling
   you might have another integration that is making old calls (not one of the Klaviyo
   integrations that are in your integration setup but maybe you are working with
   a different 3rd party).
 * If you are on a free plan, I’d recommend following these steps to download your
   API usage report to see whether you are making any v1/v2 calls: [https://developers.klaviyo.com/en/docs/audit_your_klaviyo_api_usage](https://developers.klaviyo.com/en/docs/audit_your_klaviyo_api_usage).
   You’ll be looking for any /v1 /v2 /track or /identify calls. Also keep in mind
   that the report goes back 14 days so if you upgraded your WooCommerce integration
   recently, you might want to wait until 14 days later to run the report.

 * Thanks, I looked at the API Usage report. The only other code on the site is 
   signing up a user to Klaviyo but I’m using the official PHP SDK for that [https://github.com/klaviyo/klaviyo-api-php](https://github.com/klaviyo/klaviyo-api-php)
 * I will open a ticket on the Klaviyo site, since this doesn’t seem to be related
   to the WordPress plugin.
