# I received a Sources API error: How should I handle it?

If you have an existing Stripe integration with the Sources API and have started receiving errors, please check the email address associated with your Stripe account – we have been contacting all users with information regarding their migration deadline.
If you’re integrating with Stripe for the first time, this integration path has reached end-of-life (EOL) and no longer supports new integrations. You should follow the instructions in our docs [to integrate with our newer APIs](https://stripe.com/docs/payments/payment-methods/transitioning). If you hit this error after downloading a third-party payments plugin, ensure that you have downloaded the latest version of the plugin ([follow the link to instructions for common third-party integrations](/questions/common-third-party-integrations?locale=en-US)). If you already have done this, you should contact the plugin owner or third-party developer to request that they update their integration. Please also let Stripe know by [contacting us here](/contact/email?question=other&topic=api_integration&subject=%20Support%20with%20Sources%20migration%20requirement&refcode=bP5x).
If you’re integrated with Stripe via Woo Commerce, you should [enable Woo’s latest checkout experience](https://woo.com/document/stripe/admin-experience/new-checkout-experience/) in the Stripe WooCommerce Extension advanced settings.
If you have an existing Stripe integration with the Sources API and use a different Stripe account to run an automated test suite that has now started receiving errors, please [contact us here](/contact/email?question=other&topic=api_integration&subject=%20Support%20with%20Sources%20migration%20requirement&refcode=R9fB).
