Create a pre-filled message link
Build a link that opens New Message with a subject and/or recipients pre-filled.
You can link straight to a New Message screen β handy inside a requirement, task, or event description. The base is /messages/new on your site (USA: app.rescuehub.com, Canada: ca.rescuehub.com).
- Pre-fill the subject: add
?subject=...with the text URL-encoded (e.g.?subject=January%2026%20HazMat%20Drill). - Pre-fill recipients: add
?user_ids=676,677using each person's user ID (found in the URL of their profile). Combine both with&:/messages/new?user_ids=676,677&subject=....
Use a tool like urlencoder.org to encode subjects and comma-separated IDs.
