Schedule broadcast - Resend Go SDK

Scheduling broadcasts is handled through the Send broadcast method by providing the scheduled_at parameter.

How to schedule

To schedule a broadcast, use the Send method with a scheduled_at value:

params := &resend.SendBroadcastRequest{
    BroadcastId: "brd_123456",
    ScheduledAt: "2024-12-01T19:32:22.980Z",
}

response, err := client.Broadcasts.Send(params)

You can also schedule during broadcast creation:

params := &resend.CreateBroadcastRequest{
    Name:        "Scheduled Newsletter",
    SegmentId:   "seg_123456",
    From:        "hello@example.com",
    Subject:     "Weekly Newsletter",
    Html:        "<h1>This week's updates</h1>",
    Send:        true,
    ScheduledAt: "2024-12-01T19:32:22.980Z",
}

broadcast, err := client.Broadcasts.Create(params)

Schedule formats

The scheduled_at parameter accepts two formats:

ISO 8601 timestamp

ScheduledAt: "2024-12-01T19:32:22.980Z"

Natural language

ScheduledAt: "in 1 min"
ScheduledAt: "in 2 hours"
ScheduledAt: "tomorrow at 9am"

Complete example

package main

import (
    "fmt"
    "github.com/resend/resend-go/v2"
)

func main() {
    client := resend.NewClient("re_123456789")

    // Create a draft broadcast first
    createParams := &resend.CreateBroadcastRequest{
        Name:      "Product Launch",
        SegmentId: "seg_123456",
        From:      "hello@example.com",
        Subject:   "New Product Launch",
        Html:      "<h1>Check out our new product!</h1>",
    }

    broadcast, err := client.Broadcasts.Create(createParams)
    if err != nil {
        panic(err)
    }

    // Schedule the broadcast
    sendParams := &resend.SendBroadcastRequest{
        BroadcastId: broadcast.Id,
        ScheduledAt: "2024-12-01T19:32:22.980Z",
    }

    response, err := client.Broadcasts.Send(sendParams)
    if err != nil {
        panic(err)
    }

    fmt.Println("Broadcast scheduled:", response.Id)
}
