Updates the data source object — the properties, title, description, or whether it's in the trash — of a specified data source under a database.
Returns the updated data source object.
Data source properties represent the columns (or schema) of a data source. To update the properties of a data source, use the properties body param with this endpoint. Learn more about data source properties in the data source properties and Update data source properties docs.
To update a relation data source property, share the related database with the integration. Learn more about relations in the data source properties page.
For an overview of how to use the REST API with databases, refer to the Working with databases guide.
How data sources property type changes work
All properties in pages are stored as rich text. Notion will convert that rich text based on the types defined in a data source's schema. When a type is changed using the API, the data will continue to be available, it is just presented differently.
For example, a multi select property value is represented as a comma-separated list of strings (eg. "1, 2, 3") and a people property value is represented as a comma-separated list of IDs. These are compatible and the type can be converted.
Note: Not all type changes work. In some cases data will no longer be returned, such as people type → file type.
Interacting with data source rows
This endpoint cannot be used to update data source rows.
To update the properties of a data source row — rather than a column — use the Update page properties endpoint. To add a new row to a database, use the Create a page endpoint.
Recommended data source schema size limit
Developers are encouraged to keep their data source schema size to a maximum of 50KB. To stay within this schema size limit, the number of properties (or columns) added to a data source should be managed.
Data source schema updates that are too large will be blocked by the REST API to help developers keep their data source queries performant.
Errors
Each Public API endpoint can return several possible error codes. See the Error codes section of the Status codes documentation for more information.
The following data source properties cannot be updated via the API:
formulastatus- Synced content
place
Data source relations must be shared with your integration
To update a data source relation property, the related database must also be shared with your integration.
