Hosted Integration Prefill

prefill
has been deprecated and will be replaced by the fields
attribute.
View our migration guide for more information.
Use the prefill parameter to prefill input fields in form entry verifications such as Basic and SSN. See Verification Types for all form entry verifications.
The prefill value should be an object encoded as a string using a library like qs.
All attributes are optional. You only need to include keys for form fields you want prefilled. Individuals can still edit attributes after they’re prefilled.
