/v2/locations/custom-attributes/bulk-upsert
Creates or updates custom attributes for locations as a bulk operation.
Use this endpoint to set the value of one or more custom attributes for one or more locations. A custom attribute is based on a custom attribute definition in a Square seller account, which is created using the CreateLocationCustomAttributeDefinition endpoint. This BulkUpsertLocationCustomAttributes
endpoint accepts a map of 1 to 25 individual upsert requests and returns a map of individual upsert responses. Each upsert request has a unique ID and provides a location ID and custom attribute. Each upsert response is returned with the ID of the corresponding request. To create or update a custom attribute owned by another application, the visibility
setting must be VISIBILITY_READ_WRITE_VALUES
.
