A trigger is the PDF Builder event that starts a workflow. An action is what FlowMattic does in PDF Builder from a step.
| Event | What it does | Type |
|---|---|---|
| Generate PDF from Template | Pick a saved PDF template, supply dynamic data (as JSON or per-parameter inputs), and save the rendered PDF to the Media Library. | Action |
| Delete PDF Template | Permanently delete a PDF template by its id. Idempotent — deleting a template that no longer exists returns success. | Action |
| Generate PDF from HTML | Convert your own HTML (with CSS) into a PDF and save it to the Media Library. Use Cloudflare Browser Rendering for full CSS fidelity, or the built-in engine with no external service. | Action |
The builder keeps the order you think in: connect the app, choose what starts the workflow, add what should happen.
Add a PDF Builder connection under Connects and reuse it in every workflow. Credentials stay in your WordPress database.
Start from a WordPress event, a form, a webhook, a schedule or any of the 918+ integrations, then capture a sample so later steps can map real fields.
Chain PDF Builder actions with Router, Filter, Iterator and Delay, test each step against captured data, then switch the workflow on.
Each example pairs PDF Builder with an app it is often used with. Build any of them on the canvas, or start from the workflow library.
