Cannot Create Similar User List: USER_LIST_MUTATE_NOT_SUPPORTED

[ra...@woopra.com]

I am attempting to allow users to create a SimilarUserList to a list they already have.  I send a mutate ADD operation with the seedListId, and receive [UserListError.USER_LIST_MUTATE_NOT_SUPPORTED @ operations[0].operand].

Does this mean that one cannot programmatically create a SimilarUserList?  The docs make it seem like you can as it says the seedListId is required when using operator ADD:

seedUserListId

Filterable ReadOnly Required Selectable xsd:long Seed UserListId from which this list is derived. This field can be selected using the value "SeedUserListId". This field can be filtered on. This field is read only and will be ignored when sent to the API for the following Operators: SET. This field is required and should not be null when it is contained within Operators : ADD.

Any thoughts?

Thanks!

Hi Ralph,

Could you please send me the SOAP request and response that caused this error? I will try to recreate the scenario on my end. Please send it through Reply privately to author.

Hello Ralph,

After going through the document, I found that SimilarUserLists are read-only and are automatically created by Google. Please ignore what it says under the seedUserListId. I will reach out to the team to make the document clearer.

Thanks Anthony.

Hi Anthony,

Are there any plans to make SimilarUserLists mutatable in the future? As of v201609, the documentation still suggests that an ADD will be accepted. (I did see the link you posted - that was helpful.) For our use case it would be helpful to prioritize certain SimilarUserLists over others, but that doesn't seem possible, especially without a way to explicitly request their creation...

Hi Evan,

I cannot say whether or not we plan on adding this feature in the future. You could follow our blog to get any updates.

In the future, could you please create a new thread since it is easier for us to track :)
