Help with syntax for /folders API call to retrieve custom field

I'm using the Get Folder Tree API call and need to add a single custom field to the response for each project. The doc is sparse on syntax examples (https://developers.wrike.com/api/v4/folders-projects/#get-folder-tree), and so far I haven't been able to get this working.

This call succeeds but doesn't actually include any custom fields in the response.

{{Wrike API}}/folders/{{MASKED}}/folders?fields=["customFields"]

Nothing I've tried to specify an individual custom field to retrieve has helped (results in "invalid_parameter" error).

I'm missing something simple here, I'm sure. I'd appreciate any/all help!

I had the same issue and just figured it out. You need to include the parameter "descendants=false". when you don't include it (default), it doesn't include the customFields response parameter. They used this parameter in an example in their documentation but didn't specify that it was needed to get back customField values:

curl -g -X GET -H 'Authorization: bearer eyJ0dCI6InAiLCJhbGciOiJIUzI1NiIsInR2IjoiMSJ9.eyJkIjoie1wiYVwiOjI0NDYwMDAxLFwiaVwiOjIsXCJjXCI6MTAwMSxcInZcIjpcIlwiLFwidVwiOjMsXCJyXCI6XCJVU1wiLFwic1wiOltcIk5cIixcIklcIixcIldcIixcIkZcIixcIktcIixcIlVcIixcIkNcIixcIkFcIixcIkxcIixcIlBcIixcIkJcIixcIkRcIl0sXCJ6XCI6W10sXCJ0XCI6MTc1NjM3Mzc3NzAwMH0iLCJleHAiOjE3NTYzNzM3NzcsImlhdCI6MTc1NjM3MDE3N30.jKcvJVNLvrCtp51LpRjYrN5Q_SC8MvpMscKQS8oaRoQ' 'https://www.wrike.com/api/v4/folders/IEAXKOXBI4AB5BET/folders?fields=["customFields","space"]&descendants=false'
