ListMessages Method

Lists the messages in a mailbox.

Syntax

gmail.listMessages(filter, threadId, [callback])

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for this method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This method lists the messages found in the mailbox. This method populates the MessageInfo* properties.

If the number of messages is greater than the message page size, NextPageToken will be populated and calling ListMessages again will list the next page of messages.

filter can be used to retrieve a specific subset of messages, or it can be left as an empty string to retrieve all messages in a mailbox.

threadId can be used to retrieve a specific subset of messages from a specific thread, or it can be left as an empty string to retrieve all messages in a mailbox.
