Answer 1

I have encountered this exact issue, however I have good and bad news from my experience, sometimes the API would shut me out when I had made literally no changes, sometimes rebooting the NGINX server would fix this.

At the moment my connection with postman and OAuth 1.0 yields the following;

{
  "code": "woocommerce_rest_cannot_view",
  "message": "Sorry, you cannot list resources.",
  "data": {
    "status": 401
  }
}

With that our of the way:

1. Ensure the 'Type' is set to OAuth 1.0 in postman.
2. Ensure your URL is correct, (http, or https).

As I said above, I never managed to keep mine stable, and it would drop out without changing a single thing.

How I solved this was by using 'Basic Auth', Username your_ck , password your_cs . I believe that you need to be using SSL to use Basic Auth but setting up SSL isn't a big deal so it was definitely worth it.

If you do find out why OAuth 1.0 is failing i'd love to hear.

EDIT: There are many examples of people with this issue example with image may help you. But it seems most people settle for Basic Auth.

Make sure you have given Read/Write Access to the user and also check your .htaccess file in the root directory. Try using this code in .htaccess file

# BEGIN WordPress
# The directives (lines) between `BEGIN WordPress` and `END WordPress` are
# dynamically generated, and should only be modified via WordPress filters.
# Any changes to the directives between these markers will be overwritten.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

I also faced same issue, i tried in Postman, PHP, NodeJs everthing, almost spend 2 days but no output, finally started getting response after putting a slash at the end of the URL,

I mean,

Initially i was using https://example.com/wp-json/wc/v3/products?consumer_key=ck_XXXX&consumer_secret=cs_XXXX but change it to like this https://example.com/wp-json/wc/v3/products/?consumer_key=ck_XXXX&consumer_secret=cs_XXXX (Just put a slash before question mark in the start of query string).

In Postman even without set any Authorization settings(Type = No Auth), i started getting responses.

It may be somehow related to my .htaccess, but i feel it would good if i post this solution also here.
