Working with Metadata

You can create or update metadata. A custom metadata can be added while uploading the object. Once the object is uploaded, default system metadata will be attached.

If tenant is operating for a subtenant object, the subtenant should be specified in the request query parameter. A maximum of 8 tags are allowed, where each tag can have a maximum of 128 characters.
