Boolean fields will always return a non-string “true” or “false” in responses, and the API can accept different variations of true or false for create or update requests without needing to specify a lookup type. The only accepted values for boolean fields are below:
true/false
"yes"/"no"
"true"/"false"
"EQTRUE"/"EQFALS"
Similar to countries, when setting these fields with POST or PATCH requests to the API, nothing needs to be explicitly provided as query string parameters to specify what values are being provided - there is built-in logic that will set the field as either 'true' or 'false'
