After Activation
Section titled “After Activation”The addon:
- Registers the WPsigner app in the FlowMattic workflow builder
- Writes a loader in
wp-content/flowmattic-apps/wpsigner/so FlowMattic can discover the app - Remembers which template created a document, so later triggers can filter by template
- Adds a card on WPsigner → Addons
- Adds FlowMattic → WPsigner for privacy settings
If FlowMattic or WPsigner is missing, administrators see an error notice. The app does not appear in the builder until both dependencies and this addon are active.
If WordPress cannot write wp-content/flowmattic-apps/wpsigner, an admin warning explains that FlowMattic may not list WPsigner until that folder is writable.
First Workflow
Section titled “First Workflow”- Open FlowMattic → Workflows and create a workflow.
- Choose the app WPsigner and the trigger Document completed. Leave the template on Any template.
- Add an action — for a smoke test, email yourself and map
DOCUMENT_TITLE. - Turn the workflow On.
Then complete a test document in WPsigner. The workflow should run. A workflow left Off does not run, and capture while it is Off may not record a sample.
Settings After Install
Section titled “Settings After Install”Open FlowMattic → WPsigner and decide whether signing URLs belong in workflow data. Default is on. Details: Settings.
