Title: Legacy API Issue Last modified: May 15, 2024 --- # Legacy API Issue * Resolved [Lasha](https://wordpress.org/support/users/lashac/) * (@lashac) * [1 year, 12 months ago](https://wordpress.org/support/topic/legacy-api-issue/) * Hi. * I use Printful plugin on Woocommerce. It needs Legacy API. So, when it was depricated, Woocomemrce automatically installed plugin for Legacy API. * Today there was notification that that Legacy API plugin and High Performace Order Storage don’t work together. So, I switched to old version of order storage and now I cant log in to my website, there is a critical error. * this is the log: An error of type E_ERROR was caused in line 111 of the file / home/1166517.cloudwaysapps.com/ssagpjndzx/public_html/wp-content/plugins/woocommerce- legacy-rest-api/includes/class-wc-legacy-rest-api-plugin.php.

I would revert back to a recent backup. I’m sorry I can’t find the link right now. * Thank you. * Thread Starter [Lasha](https://wordpress.org/support/users/lashac/) * (@lashac) * [1 year, 12 months ago](https://wordpress.org/support/topic/legacy-api-issue/#post-17757824) * Yes, I restored my backup. * So, there is an update for Legacy APi plugin and I won’t update it. I also have High-performance order storage (recommended) enabled. If I switch to WordPress posts storage (legacy), it will break the site again. * When you fix that issue. I need Legacy APi feature because Printful plugin needs it. * [Stef](https://wordpress.org/support/users/serafinnyc/) * (@serafinnyc) * [1 year, 12 months ago](https://wordpress.org/support/topic/legacy-api-issue/#post-17757857) * Hello [@lashac](https://wordpress.org/support/users/lashac/) * > I need Legacy APi feature because Printful plugin needs it * That is not correct. You can simply use the [app](https://wordpress.org/plugins/printful-shipping-for-woocommerce/) to connect directly to Printful avoiding any necessary tokens or API keys. * Most authors have already updated their apps to work with REST API. In fact I believe Printful is sunsetting their legacy connection as well. * If you need further information on how to connect the app to your store you can [click here](https://www.printful.com/dashboard/connect/woocommerce). * Thread Starter [Lasha](https://wordpress.org/support/users/lashac/) * (@lashac) * [1 year, 12 months ago](https://wordpress.org/support/topic/legacy-api-issue/#post-17757934) * Yes I use that Printful plugin. And their support said that they will make updates to the plugin in the future. But as I know, it still needs Legacy API feature activated in Woocommerce * [Stef](https://wordpress.org/support/users/serafinnyc/) * (@serafinnyc) * [1 year, 12 months ago](https://wordpress.org/support/topic/legacy-api-issue/#post-17757951) * You do not. * I use the same app and I use HPOS and all is well in the world. They’re maybe just confusing you. * You can see [here](https://loom.com/i/bc138b7e0479496bb47f03d1d6fcf19f) I’m running Printful on my own store using REST API. All you need to do is reconnect without using the legacy (if you are even on legacy) on your instance. * Chances are you probably just have the [legacy API box checked](https://loom.com/i/707c32ef33e84dd287adf6f2df1af3a3). Just uncheck it if you don’t have any apps that require it and you’ll be fine. It will list the apps that need Legacy right there too. If printful shows up there then you are not using the latest app. * Thread Starter [Lasha](https://wordpress.org/support/users/lashac/) * (@lashac) * [1 year, 12 months ago](https://wordpress.org/support/topic/legacy-api-issue/#post-17758205) * [@serafinnyc](https://wordpress.org/support/users/serafinnyc/) * You don’t have Legacy API enabled? * Which version of Woocommerce do you have? * Mine is 8.8.3 and because Woo removed Legacy API, it automatically installed ** WooCommerce Legacy REST API** plugin, so Legacy API feature is still enabled. * [Stef](https://wordpress.org/support/users/serafinnyc/) * (@serafinnyc) * [1 year, 12 months ago](https://wordpress.org/support/topic/legacy-api-issue/#post-17758209) * I have the latest of everything on that instance. I do not have Legacy enabled. You most likely did/do and that’s why the app was automatically added in case you did need it come this June or whenever the deprecation is coming. * However none of the on demands require Legacy anymore. You can just uncheck the box as I stated above in the one screenshot if no other apps require it. Hopefully you don’t have any. Everyone has pretty much had direct connections for some time now. * Just check that box, and then you can delete the Legacy API app * Thread Starter [Lasha](https://wordpress.org/support/users/lashac/) * (@lashac) * [1 year, 12 months ago](https://wordpress.org/support/topic/legacy-api-issue/#post-17758219) * No other plugin requires it. I will contact Printful support again and wait for their response. * [Stef](https://wordpress.org/support/users/serafinnyc/) * (@serafinnyc) * [1 year, 12 months ago](https://wordpress.org/support/topic/legacy-api-issue/#post-17758251) * Then you’re all set. If you are using Printful’s app then you are directly connected. It adds itself to the REST API. * [ckadenge (woo-hc)](https://wordpress.org/support/users/ckadenge/) * (@ckadenge) * [1 year, 11 months ago](https://wordpress.org/support/topic/legacy-api-issue/#post-17765735) * Hi there [@lashac](https://wordpress.org/support/users/lashac/), * Just wanted to check in and follow up on the issue, were you able to get assisted by Printful’s support? Do you still any further assistance or was the issue resolved? * Thread Starter [Lasha](https://wordpress.org/support/users/lashac/) * (@lashac) * [1 year, 11 months ago](https://wordpress.org/support/topic/legacy-api-issue/#post-17780692) * They said that I should have Legacy API enabled before they update the plugin. * Plugin Support [omarfpg a11n](https://wordpress.org/support/users/omarfpg/) * (@omarfpg) * [1 year, 11 months ago](https://wordpress.org/support/topic/legacy-api-issue/#post-17784589) * Hi [@lashac](https://wordpress.org/support/users/lashac/), * As I understand, you’re trying to work with: - WooCommerce 8.9.1 - [The WooCommerce Legacy REST API plugin](https://wordpress.org/plugins/woocommerce-legacy-rest-api/) - [The Printful Integration for WooCommerce plugin](https://wordpress.org/plugins/printful-shipping-for-woocommerce/) - And [HPOS](https://developer.woocommerce.com/roadmap/high-performance-order-storage/) enabled * You need the Legacy REST API as per Printful instructions, but when you enable this plugin with HPOS you get an error, correct? I just tried the Legacy REST API plugin + HPOS and didn’t get an error; so far, so good. I then also installed the Printful plugin but no error whatsoever yet. * Can you share more details about what you are trying to do when you get this error? I’d love to replicate this issue to learn more. * Please also share a screenshot of your WooCommerce Settings → Advanced → Rest API and Legacy API. * In the meantime, I’d like to understand your site properly and what’s causing this crash with the Printful plugin, Legacy REST API and HPOS. Please share with us the necessary information below for us to investigate the issue further: - **System Status Report** which you can find via WooCommerce > Status > Get system report > Copy for support. - **Fatal error logs** (if any) under WooCommerce > Status > Logs. * You could copy and paste your reply here or paste it via [https://gist.github.com/](https://gist.github.com/) and send the link here. * Once we have more information, we’ll be able to assist you further. * Thanks! -OP * [Stef](https://wordpress.org/support/users/serafinnyc/) * (@serafinnyc) * [1 year, 11 months ago](https://wordpress.org/support/topic/legacy-api-issue/#post-17784774) * [@lashac](https://wordpress.org/support/users/lashac/) I have my own stores and I sell my own artwork using Printful and I am not using anything Legacy. So I think you’re getting bad information from someone. There is no need for Legacy API with Printful. * Thread Starter [Lasha](https://wordpress.org/support/users/lashac/) * (@lashac) * [1 year, 11 months ago](https://wordpress.org/support/topic/legacy-api-issue/#post-17785122) * [@omarfpg](https://wordpress.org/support/users/omarfpg/) Hi. * Website works. I got that error once, when I updated Legacy Plugin. Then I just restored backup and that’s it. * [Stef](https://wordpress.org/support/users/serafinnyc/) * (@serafinnyc) * [1 year, 11 months ago](https://wordpress.org/support/topic/legacy-api-issue/#post-17786103) * Understood [@lashac](https://wordpress.org/support/users/lashac/) but just know there’s no need for anything legacy related to Printful. I don’t want to confuse others that might see this post and have them think it’s required.
