Remove a Metadata Item |
Removes a metadata item by deleting a specific key-value pair in the target file.
Metadata is a collection of name-to-object mappings. Data can be bound to the name for later retrieval. The name (or "key") must be unique and is case-sensitive. The developer is responsible for setting the object value that is associated with this key. The recommended data format is JSON.
The storage that is consumed by a file's metadata must be less than 10MB. If you try to store more than a total of 10MB, a storage error may occur. If you need to associate large data elements with a specific file version, consider using the Add a File Attachment API instead.
