Rest Authentication Error

Hi @ante1974!

This issue seems to be from the external print-on-demand service you are using.

That error message you get means that the call made from that service to the WooCommerce API has an authentication problem.

We recommend reaching their customer support team for further assistance since they are the most suitable to deal with your query.

I hope this helps!

@judagutor Thanks for this, so the problem is with the print-on-demand service. I will let them know, because they said the problem is my end.

Is there any information I can send them from the logs or, browser inspector that could help them resolve the problem?

Hi @ante1974

If the problem has generated any fatal errors then you could share those. Navigate to WooCommerce > Status > Logs and from the dropdown on the right side, please see if there are any logs starting with the words fatal-error.

FYI, authentication issues are covered in the WooCommerce REST API documentation which you may find helpful: https://woocommerce.github.io/woocommerce-rest-api-docs/#authentication-over-https

You can also check these threads where the same issue has been discussed:

– https://github.com/woocommerce/wc-api-php/issues/175

I hope you find this information useful.

@margaretwporg thanks for the update.

This problem is now resolved and actually had been caused by a firewall setting on my website. I initially integrated when my website accepted both http and https connections but recently changed my firewall to only allow https connections. Apparently the integration was implemented over http, and now I only accept https connections, this error appears to be thrown.

I hope this makes sense.

Hi @ante1974,

Glad to hear you got this sorted! Thanks for letting us know what was causing the issue.

Now that the issue is resolved, feel free to create a new topic if you need assistance with anything else.
