deleteMessages

@Nonnull
@CheckReturnValue
default RestAction<Void> deleteMessages(@Nonnull
 Collection<Message> messages)

Bulk deletes a list of messages. This is not the same as calling Message.delete() in a loop.
This is much more efficient, but it has a different ratelimit. You may call this once per second per Guild.

Must be at least 2 messages and not be more than 100 messages at a time.
If you only have 1 message, use the Message.delete() method instead.

You must have the Permission MESSAGE_MANAGE in this channel to use this function.

This method is best used when using MessageHistory to delete a large amount of messages. If you have a large amount of messages but only their message Ids, please use deleteMessagesByIds(Collection)

Possible ErrorResponses include:

• UNKNOWN_CHANNEL
  if this channel was deleted
• UNKNOWN_MESSAGE
  if any of the provided messages does not exist
• MISSING_ACCESS
  if we were removed from the guild
• MISSING_PERMISSIONS
  The send request was attempted after the account lost Permission.MESSAGE_MANAGE in the channel.

Parameters:

messages - The collection of messages to delete.

Returns:

AuditableRestAction

Throws:

IllegalArgumentException - If the size of the list less than 2 or more than 100 messages.

InsufficientPermissionException - If this account does not have Permission.MESSAGE_MANAGE

See Also:

• deleteMessagesByIds(Collection)
• MessageChannel.purgeMessages(List)

deleteMessagesByIds

@Nonnull
@CheckReturnValue
RestAction<Void> deleteMessagesByIds(@Nonnull
 Collection<String> messageIds)

Bulk deletes a list of messages. This is not the same as calling MessageChannel.deleteMessageById(String) in a loop.
This is much more efficient, but it has a different ratelimit. You may call this once per second per Guild.

Must be at least 2 messages and not be more than 100 messages at a time.
If you only have 1 message, use the Message.delete() method instead.

You must have Permission.MESSAGE_MANAGE in this channel to use this function.

This method is best used when you have a large amount of messages but only their message Ids. If you are using MessageHistory or have Message objects, it would be easier to use deleteMessages(java.util.Collection).

Possible ErrorResponses include:

• UNKNOWN_CHANNEL
  if this channel was deleted
• UNKNOWN_MESSAGE
  if any of the provided messages does not exist
• MISSING_ACCESS
  if we were removed from the guild
• MISSING_PERMISSIONS
  The send request was attempted after the account lost Permission.MESSAGE_MANAGE in the channel.

Parameters:

messageIds - The message ids for the messages to delete.

Returns:

AuditableRestAction

Throws:

IllegalArgumentException - If the size of the list less than 2 or more than 100 messages.

NumberFormatException - If any of the provided ids cannot be parsed by Long.parseLong(String)

InsufficientPermissionException - If this account does not have Permission.MESSAGE_MANAGE
