# Plugin causing WC API products failure

* Hi there,
* We’ve been using your plugin on our WooCommerce website for a number of years.
We only use the TAX Display module for the tax toggle functionality.
* In the past couple of weeks we’ve updated our WP, Woo and all plugins for the
first time in a little while. At first it seemed everything was working well
but I’ve just noticed that the API call between our website and our inventory
management system has failed since the date we updated your plugin. It works
fine for all pages except the last and then fails before completion.
* When I recreate the exact API call in Postman (which is: /wc-api/v3/products)
it works okay except for the very last page of results, where the following is
being printed before the start of the “products” JSON:
* ```wp-block-code
```
* I have edited the key and secret for security.
* The above is obviously malforming the JSON and therefore producing a failure.
* I’m not sure why this is happening but how do I go about preventing the above
from being printed above the JSON in the API response?
* Thanks in advance,
Jack

* To add some more context to this bug I’m seeing:
1. It’s not a caching issue or anything related to caching, with all caching plugins
disabled, this issue still occurs
2. Disabling your plugin resolves the issue
3. Keeping your plugin enabled but disabling the tax display module completely,
the problem still occurs
* So it’s a strange one, and I don’t completely understand why with the tax display
module disabled the tax display nonce is still being echoed above my WC-API response.
* I did find one “fix”, but since it relies on me directly modifying your plugin
source code, I don’t really class it as a fix.
* Changing wcj_button_toggle_tax_display() in class-wcj-general-shortcodes.php
to the following resolves the issue:
* ```wp-block-code
public function wcj_button_toggle_tax_display( $atts ) {
/* CUSTOM */
$urlParts = explode('/', $_SERVER['REQUEST_URI']);
if ($urlParts[1] === 'wc-api' || $urlParts[1] === 'wp-json')
return '';
/* CUSTOM */
$session_value = wcj_session_get( 'wcj_toggle_tax_display' );
$current_value = ( ( '' === $session_value || null === $session_value ) ? wcj_get_option( 'woocommerce_tax_display_shop', 'excl' ) : $session_value );
$current_value = '' === $current_value ? 'excl' : $current_value;
$label = $atts[ 'label_' . $current_value ];
return '';
}
```
* So I will go with the above solution for now, but obviously as soon as I update
your plugin, it’s going to resort back to the issue being present, so I would
really appreciate one of your developers chiming in on this.
* Many thanks,
Jack
