How to send many messages in a moment?

[SirotovAlexander]

Hi! In TG bot i receive array of channels link. And need send messages to all of it. But when i try send it in a cycle using funk (Api.messages.SendMessage), i received error. What i need to do?

I have next construction in code:
client.invoke(
new Api.messages.SendMessage({
// peer: "two_face_project",
noWebpage: true,
background: true,
clearDraft: true,
peer: ${chanelList},
replyToMsgId: 6872073,
message: ${adMessage},
randomId: Math.floor(Math.random() * 1000000),
scheduleDate: 789917,
})
);
