Hey @samsiddiquiz,

One can't "add a field to folder" but can update item (which already in folder) or create a new item in the folder. addValidateUpdateItemUsingPath can be used for creating items in a folder. Here is the sample.

Hey @koltyakov
Thank you, i am trying to create item in folder, where field is Person and Group Multiple is true, can you guide me how to set FieldValue for Person and Group Multiple field ?

MultiUser payload you mentioned is correct, so validateUpdateListItem for updates and addValidateUpdateItemUsingPath for item creation.

Example:

sp.web.lists.getByTitle('List Name').items.getById(1)
    .validateUpdateListItem([
        { 
            FieldName: 'MultiUser',
            FieldValue: JSON.stringify([
                { Key: 'i:0#.f|membership|user1@contoso.onmicrosoft.com', IsResolved: true },
                { Key: 'i:0#.f|membership|user2@contoso.onmicrosoft.com', IsResolved: true },
                { Key: 'i:0#.f|membership|user3@contoso.onmicrosoft.com', IsResolved: true }
            ])
        }
    ])
    .then(console.log);
