Hi, this feature (opening composer to compose a new personal message/topic via URL is very useful: [image] Creating pre-filled personal message links Using Discourse bookmark This guide describes how to create a link to start a new personal message with pre-filled information, including best practices. person_raising_hand Required user level: All users Discourse allows you to compose a new personal message with pre-filled information via URL parameters. This can save time and ensure consistency for common messages. Structure of the URL To create a new pre-filled message, format your URL like this: https://discourse.example.com/new-message?username… However we would like to open the composer in an existing personal message topic/discussion, via URL (or at least somehow from an external site (linked via SSO) . Is this is this possible?

I don’t think this is possible at the moment. Can you explain more about the use case here?

We are using PMs for projects on a site, and each project gets its own message topic. The head-scratcher is how a person can post a message to the topic with content from the project. So really would like a button on the site to post content to message topic, essentially. But then continue composing. Does that make sense?

Got it. Discourse design is mostly around each project of yours existing as a category, subcategory or tag. That way you don’t end with lots of The MEGATOPIC: public good, or public menace?, and information is better organized. If you are locked into this long PM design, you will probably need a theme-component to allow to pop-up the reply composer from a URL param.

Good reply, thanks. By theme component, do you mean a plugin type development project? We investigated using categories/subcategories using an auto-create routine, however found that the number of projects we tested meant categories got beyond what Discourse could handle (think it started to cause problems above 500 or so.) Tags have no privacy, so can’t use those. So, instead using groups…and PMs, which is working well.
