I was tired of trying to select exactly the token part of the JSON so I can paste it into Postman, so I made this
javascript:window.location.href.includes(".com/documents")?$.post(window.location.origin+"/system/api/v1/security/token").done((e=>{let o=document.createElement("input");o.value=e.accessToken,document.body.appendChild(o),o.select(),document.execCommand("copy"),document.body.removeChild(o)})).fail(((e,o,t)=>{alert("Failed with HTTP code:"+e.status)})):alert("Only usable from OCM dashboards")
I was tired of inspecting, finding the li and the ID, then going to the documents, entering a folder, pasting my ID over the ID in the URL. As a nice benefit, it also copies selected asset IDs from the viewer, and document IDs from the documents page.
