Field reference of the question where the answer should be updated.

The answer value as a string. The required format depends on the field type.

🚧

JSON-encoded string required

For Name and Address fields the value must be a serialised JSON string — not a nested JSON object.

Name — "{\"first\":\"John\",\"middle\":\"Michael\",\"last\":\"Smith\"}" (omit middle unless UseMiddleName is true).

Address — "{\"address\":\"123 Main St\",\"city\":\"Brisbane\",\"state\":\"QLD\",\"zip\":\"4000\",\"country\":\"Australia\"}"

Other field types — send the value directly:

• DateTime: yyyy-MM-dd HH:mm
• Email: [email protected]
• Phone: (123) 456-7890
• Number / Currency: digits only (e.g. 123456789)
• Id (ABN/ACN/EIN/SSN/CRN): see the Answer formats guide

For Checkbox, Radio, Select and Linked fields, leave Answer empty and use AnswerRef instead.

• Linked Field — multiple record refs joined by semicolon, e.g. 100912758;100912759. For repeatable fields, append the repeat index using ~, e.g. 100912758~1;100912759~2
• Radio or Select/Dropdown — single option ref, e.g. 12345
