Create or update a strain through a single endpoint: omit id to create a new strain, or pass the id of an existing one to update it in place. A strain is a catalog/reference record used to classify products by genetics — it holds no inventory and is not pushed to Metrc or BioTrack, so calling this never moves stock or touches state-compliance traceability. What it does affect is your product catalog and menus: products are grouped under a strain, so renaming a strain or changing its type reflects everywhere that strain is shown, without altering the products themselves. To remove a strain from your catalog entirely, use the delete endpoint instead.

Updates are sparse. Only the fields you send are changed; any field you omit keeps its current value (sending id with just name renames the strain and leaves strain_type untouched). The whole write is a single all-or-nothing operation — if validation fails, nothing is persisted and a 400 is returned with the field errors.

name must be unique within your company; reusing an existing strain's name is rejected with a 400. On success the response is the full created or updated strain, the same shape as show.
