How to troubleshoot Zapier in Yoast SEO Premium

Sometimes, when you use Zapier with Yoast SEO Premium, you may run into some errors. This troubleshooting guide lists the most commonly found errors, their causes, and the steps you can take to fix them.

If Yoast SEO is not connected to Zapier, click on the Connect to Zapier button and follow the steps in the popup window.

Test the connection between Zapier and Yoast SEO

  1. Log in to your Zapier account and click on ‘My apps’ > ‘Yoast SEO’.
  2. Click on the three dots and then on ‘Test connection’, as shown in the image below.
  3. If it shows a ‘Test successful’ notification, Zapier and Yoast are working on the site. If not, please click on the dots and select ‘Reconnect’. Then, follow the steps to reconnect and see if the issue resolves.

A Zap is not triggered when I publish a new post

If you created a Zap, but it is not triggered when you publish a new post, check the following:

  • Make sure you’ve followed the configuration guide on how to create a Zap.
  • Go to Zapier, click on Zaps, and ensure you’ve enabled the Zap. If the toggle is off (like in the screenshot below), switch it on.



  • Click the tree dots next to the toggle and select History to check the status of your Zap. You can go to the Zapier help center to learn more about managing and viewing your task history.


  • Do a plugin conflict check to see if the problem occurs when all non-Yoast plugins are disabled and your active theme is TwentyTwenty.

Other possible errors you may encounter 

These are the errors that you may encounter when using Yoast SEO and Zapier:

Subscription failed. A subscription already exists. 

Cause: You are getting this error because you are trying to set up a second Zap, which requires a Premium Zapier plan.

Solution: Instead of creating multiple Zaps, you can try adding multiple actions to a single Zap

Error: authentication failed: The app returned “Server Error”. What happened (You are seeing this because you are an admin): Stack trace: ResponseError: {“status”:404,”headers”

Cause: Your site uses plain permalinks and the Zapier integration requires SEO-friendly permalinks.

Solution: Choose a permalink setting to enable REST API.

The app returned “The API key does not match.”. What happened (You are seeing this because you are an admin): Stack trace: ResponseError: {“status”:500,”headers”

Cause: The API key in Zapier is not the same as the one Yoast expects.

Solution: Go to Admin > SEO > General > Integrations and copy the API key. Update the App in Zapier with the new API key.

Authentication failed: The app returned “DRA: Only authenticated users can access the REST API.”.

Cause: The REST API has been blocked for non-authenticated users by a plugin like Disable REST API.

Solution: Disable the 3rd party plugin or add an exception for the endpoints below:

/yoast/v1/zapier/subscribe

/yoast/v1/zapier/unsubscribe

/yoast/v1/zapier/check

/yoast/v1/zapier/list

We hit an error adding your new account. Authentication failed: The app returned “503”.

Cause: It may be due to different reasons. For example, when the REST API used by our plugin to connect to Zapier is blocked, i.e. by the reCaptcha protection from Cloudflare (Bot Fight mode). Zapier can provide an error log file that will help determine the exact cause of the error.

Solution: It’ll depend on the cause of the error.
