Hi @wpbuffs,

There are a few issues which can result in that message. Some of the most common causes are our system being unable to reach your server or issues with the keys you’ve provided. Since you are able to connect using the Legacy API, it sounds like it’s an issue with the keys you’re using.

The process to create a Legacy API key in WooCommerce is different from the process to create a REST API key for the V3 integration. Are you following these instructions to create the REST API key?

Best,

Caroline

Hey Caroline,

Yes, we are following the steps at https://docs.woocommerce.com/document/woocommerce-rest-api/, however, when we insert the consumer key and consumer secret, it says Unable to access the orders API, please check connection settings and try again.

So not sure which could be the problem here.

Thank you,

Hi @wpbuffs,

I would recommend initially integrating your account with the WooCommerce legacy API information (since you mentioned the integration seems to work fine with the legacy keys), and then once the integration is functioning, follow the instructions here to upgrade to the real-time integration.

Best,

Caroline

Hi, I’m having the same issue as a new customer - same error message when I try to upgrade to the real-time integration, having followed all the steps you laid out above @caroline . Can you give me a hand? The real-time info is one of the reasons we are so interested to try Klaviyo. Thanks, Sanjay

Hello @SanjayB,

Thank you for your reply and thank you @caroline for providing those steps.

@SanjayB, in order to use WooCommerce’s API v3 you must be on WC Version 3.5x or later and WP Version 4.4 or later. Can you confirm that you meet both of these requirements?

Hi @dov.derin, thanks for getting back to me so quickly. Yes, I’m on WC 5.1 and WP 5.7

Hi guys

I had the same issue… the credentials worked with the legacy api and not the current rest api…

Basically I discovered that If there’s an error with the orders response, then you won’t be able to connect… this happened in my case.

I tested the woocommerce orders request url with my consumer key and secret with the Postman app and noticed that there was an error in my code (a missing null check)… a very simple fix and now I can connect woocommerce with Klaviyo.

To test in postman… please see here: https://github.com/woocommerce/woocommerce/wiki/Getting-started-with-the-REST-API

Hello,

I`m new member here, I have encountered same issue when connect to Woocommerce: Unable to access the orders API, please check connection settings and try again. Have enabled legacy API, but also failed, how to solve this?

Hi @itsterry0908, 

Welcome to the Community! We are so happy you’re here! 

I know getting started can be difficult at first, but you will get the hang of this thing! Can you confirm that you’ve tested all of the possible solutions listed above by some of your fellow users? 

• Followed these instructions to create a rest API key, as the issue could be lie in the rest key
• If the issue still persists, initially integrating with the Woocommerce legacy API information, once the integration is functioning, follow the instructions here to upgrade to the real-time integration
• Ensuring your integration is an updated version of Woocommerce: Version 3.5x or later and WP Version 4.4 or later 
• Using the Postman app, investigating if there is a error in your code between the WC orders request url and your consumer key

If you are still experiencing issues after following all these possible troubleshooting solutions, I would reach out to our awesome Support Team as they will be able to do a deep-dive investigation into your WC integration to find the error! 

We’re so glad your a part of our Community!

We tested the woocommerce order API through postman and it is returning valid response. but integration page is returning, 

Unable to access the orders API, please check connection settings and try again.

Although API is returning valid orders. 

Hi @subtainishfaq, 

Sorry to hear you’re experiencing these issues as well!

Can you confirm that you have worked through the possible options I listed above and your integration is an updated version of Woocommerce: Version 3.5x or later and WP Version 4.4 or later? If you thoroughly checked these steps and met the requirements, I would recommend reaching out to our Support Team as they will be able to further investigate why you might be encountering this error!

Hi Diyafury, how did you fix the “Missing null check”? I’m currently in this error and I don’t have any idea how to do it.

@Diyafury 

Hi @razzorax, 

It seems like diyafury combined through her code and found the error herself. However, if you’re still experiencing this issue, I’d reach out to our awesome Support Team as they might be able to find the source of the exact error! 

Thanks for participating in the Community!
