The input for a list reference field must be formatted as a string that includes both the list type identifier and the internal identifier of the record. The format follows this structure:
<type id>:<internal id>
If multiple list references need to be passed, they should be separated by semicolons (;
). For example, if you're referencing multiple records:
type1:123;type2:456;type3:789
This format allows you to specify multiple records by their type and internal ID in a single string, making it easier to reference multiple lists in a request.
