Widget style to test
Inputs
Automatic mode: change any input and the payments update by themselves, with no button. The page waits until the ZIP has 5 digits and typing pauses for a moment.
Loading dropdowns from /v1/options…
Error simulator
Fake what the API returns when something goes wrong, so the widget's fallback can be designed. Uses the inputs above. Not counted in stats.
Pick a widget style, then fill in the inputs. Results appear here, with the raw API response underneath.
Scenario checklist
Runs every important case against the live API and checks the answer follows the rules. Use it to confirm a widget handles each one. "Load" puts a scenario into the inputs above.
Copy the code
Ready-to-paste code for the exact inputs and widget style chosen above. It updates as you change them.
