Modifies the labels on the specified messages.

Scopes

You will need authorization for at least one of the following scopes to make a valid call:

  • https://mail.google.com/
  • https://www.googleapis.com/auth/gmail.modify

If unset, the scope for this method defaults to https://mail.google.com/. You can set the scope for this method like this: gmail1 --scope <scope> users messages-batch-modify ...

Required Scalar Argument

  • <user-id> (string)
    • The user's email address. The special value me can be used to indicate the authenticated user.

Required Request Value

The request value is a data-structure with various fields. Each field may be a simple scalar or another data-structure. In the latter case it is advised to set the field-cursor to the data-structure's field to specify values more concisely.

For example, a structure like this:

BatchModifyMessagesRequest:
  add-label-ids: [string]
  ids: [string]
  remove-label-ids: [string]

can be set completely with the following arguments which are assumed to be executed in the given order. Note how the cursor position is adjusted to the respective structures, allowing simple field names to be used most of the time.

  • -r . add-label-ids=et
    • A list of label IDs to add to messages.
    • Each invocation of this argument appends the given value to the array.
  • ids=erat
    • The IDs of the messages to modify. There is a limit of 1000 ids per request.
    • Each invocation of this argument appends the given value to the array.
  • remove-label-ids=consetetur
    • A list of label IDs to remove from messages.
    • Each invocation of this argument appends the given value to the array.

About Cursors

The cursor position is key to comfortably set complex nested structures. The following rules apply:

  • The cursor position is always set relative to the current one, unless the field name starts with the . character. Fields can be nested such as in -r f.s.o .
  • The cursor position is set relative to the top-level structure if it starts with ., e.g. -r .s.s
  • You can also set nested fields without setting the cursor explicitly. For example, to set a value relative to the current cursor position, you would specify -r struct.sub_struct=bar.
  • You can move the cursor one level up by using ... Each additional . moves it up one additional level. E.g. ... would go three levels up.
