Upon activating Oauth in Magento admin, there is no request sent to the callback URL. If I try to setup normal token authentication, there are no tokens provided.
I followed the documentation for oauth. Magento will call the URL at "Identity link URL" but it will not call the URL at "Callback URL." I setup the script at the Callback URL to send me an email when it is called. I can copy/paste the Callback URL from Magento admin into Postman to confirm the script at the URL works so I am sure the URL is correct and the script will take action when it is called. I am certain Magento is not sending anything to the Callback URL after selecting Activate, selecting Allow, getting expected redirect from Identity link URL, and selecting OK. My server never saw a request at the URL entered in Callback URL.
I also tried setting up basic token authentication following the token authentication documentation. This is basically the same process but Callback URL and Identity link URL are left blank. Again, I hit Authorize and Allow but only the Consumer Key and Consumer Secret blanks are filled in where the documentation suggests Magento should also provide tokens. What I see are the Access Token and Access Token Secret remain blank.
I have tried deleting values in oauth token table. That had no impact.
I tried using Postman to post to POST mywebsite.com/oauth/token/request using the guidance provided in this post.. I am certain I had the Oauth 1.0 fields filled out exactly as described in the post. However, Magento returned
oauth_problem=oauth_consumer_key+is+a+required+field%2C+oauth_signature+is+a+required+field%2C+oauth_signature_method+is+a+required+field%2C+oauth_nonce+is+a+required+field%2C+oauth_timestamp+is+a+required+field
There is nothing in the magento/var/log/ logfiles that reflect any of the activity associated with setting up the APIs.
I was using the API successfully in the past by requesting a token using /rest/default/V1/integration/admin/token with a username and password. At some point that stopped working and I actually don't recall where I got the username and password from as it is an odd looking username that I don't see in the list of users. I am trying to set up the Oauth process in its place but having no luck at all.
Any guidance is appreciated.
