Hi Stacie, You can only *add* attributes to a Feed. You won't be able to modify existing attributes of a Feed, e.g., you won't be able to change their types.
I would recommend against relying on specific attribute IDs always being of a specific type. In particular, feeds created by the AdWords system offer no guarantees about which attribute ID will be used for each placeholder field. A better solution would be to use the FeedMapping.attributeFieldMappings <https://developers.google.com/adwords/api/docs/reference/v201502/FeedMappingService.FeedMapping#attributeFieldMappings> to look up the feedAttributeId <https://developers.google.com/adwords/api/docs/reference/v201502/FeedMappingService.AttributeFieldMapping#feedAttributeId> that corresponds to each placeholder fieldId <https://developers.google.com/adwords/api/docs/reference/v201502/FeedMappingService.AttributeFieldMapping#fieldId> . Regarding migrating to extension settings, please check out our Migration Guide <https://developers.google.com/adwords/api/docs/guides/migrate-to-extension-settings>, which includes links to code examples in each language.
