As announced back in November 2011, we've deprecated some legacy features of our API related to creating and editing listings. The following things are changing:
- The fields who_made, when_made, and is_supply will always be REQUIRED when creating listings. Previously these fields were optional.
- The field category_id will always be REQUIRED when creating listings. The previous convention of supplying categories in the "tags" field will no longer be honored.
- The data_version parameter will no longer be honored. The new behavior will be the same as it was previously when using "data_version=2011.11.01".
These changes will happen on June 19 2012, approximately two weeks from now.
Let us know if you've got any questions about this so we can address them as soon as possible!
Thank you!
