# Create metadata property option

Adds a single option to a `select_str` or `multiselect_str` property definition. Body must include `type` so the server knows which per-type option table to write.

**Endpoint:** `POST /v2/prism/{teamId}/{objectType}/properties/{propertyId}/options`  
**Operation ID:** `createMetadataPropertyOption`  
**Server:** `https://developers.micro.so`  
**Security:** `[{"apiKey":[]}]`
