Delete all Messages in Channel?

[heatdream]

Hello,
I want that in a specific Channel all messages got deleted when I run a function.
How to delete the last message works, but the discordgo.Channel.Messages doesn't work (bcs its only works with cached messages?)
So now is my question: How can i delete all messages in Channel without that the messages have to be cached?

(Sry for my bad english)

thanks

Hello, that is possible with the endpoint DeleteBulkMessage (https://discord.com/developers/docs/resources/channel#bulk-delete-messages)

session.ChannelMessagesBulkDelete(channelID string, messages []string)

But limited to 100 messages per request. If this is a big channel (basically messages > 100), the best solution is to duplicate channel and delete the full channel.

Example:

s, _ := discordgo.New()
s.Open()

ch, err := s.Channel(channelID)
if err != nil {
	panic(err)
}
if _, err = s.ChannelDelete(channelID); err != nil {
	panic(err)
}

s.GuildChannelCreateComplex(guildID, discordgo.GuildChannelCreateData{
	Name: ch.Name,
	Type: ch.Type,
	Topic: ch.Topic,
	Bitrate: ch.Bitrate,
	UserLimit: ch.UserLimit,
	RateLimitPerUser: ch.RateLimitPerUser,
	Position: ch.Position,
	PermissionOverwrites: ch.PermissionOverwrites,
	ParentID: ch.ParentID,
	NSFW: ch.NSFW,
})
