FAQ
-
How do I set up Salesforce?
-
Install the FlowIframeEmbed package (or deploy equivalent metadata), activate your Screen Flow, expose FlowIframeEmbed on a Salesforce Site, and grant guest access. See the GitHub repository and Salesforce setup guide.
-
Can I use just [Lightning-Flow-iFrame] with no attributes?
-
Yes, when you configure Default iFrame URL, Default Flow Name, and optionally Default End URL under Settings Lightning Flow iFrame.
-
Is inputvars required?
-
No. Omit inputvars when your flow needs no URL inputs. When set, only listed parameters are passed to the flow. Matching values are read from the parent page URL query string (for example
?recordId=001xxx), fromextraqs, or from shortcode attributes with the same name. -
How do parent page variables reach the flow?
-
Set
inputvarsto a comma-separated allowlist of Flow input variable API names. If the WordPress page URL includes those query parameters, the plugin adds them to the iframe URL. Example page:https://yoursite.com/form/?recordId=001xxx&source=webwith shortcode[Lightning-Flow-iFrame inputvars="recordId,source"]. -
How do I keep legacy behavior?
-
Leave Default Flow Name blank and do not add a flow attribute to your shortcode. Legacy mode forwards the full parent page query string and uses endurl (lowercase).
