The Lists SDK methods lets you create / manage list of subscribers. You can then send broadcast to all the users in the list or create a workflow that triggers when a new user enters / exits list.

​
Create / Update List

You can use suprClient.SubscriberLists.Create method to create a new list

package main

import (
  "context"
  "log"

  suprsend "github.com/suprsend/suprsend-go"
)

func main() {
  // Initialize SDK
	opts := []suprsend.ClientOption{
    // suprsend.WithDebug(true),
  }
  suprClient, err := suprsend.NewClient("__api_key__", "__api_secret__", opts...)
  if err != nil {
    log.Println(err)
  }
	ctx := context.Background()
  // ================= Create subscriber list
	subscriberListCreated, err := suprClient.SubscriberLists.Create(ctx, &suprsend.SubscriberListCreateInput{
		ListId:          "prepaid-users", // max length 64 characters
		ListName:        "Users With Prepaid Vouchers",
		ListDescription: "Users With Prepaid Vouchers above $250",
	})
	if err != nil {
		log.Fatalln(err)
	}
	log.Println(subscriberListCreated)
}

Guidelines on defining the list_id

  • list_id is case-insensitive. Suprsend first converts list_id to lowercase before storing it or doing any sort of comparison on it.
  • list_id can be of max 64 characters.
  • It can contain characters [a-z0-9_-] that is alphanumeric characters, _(underscore) and -(hyphen).

​
Get list data

You can get the latest information of a list using suprClient.SubscriberLists.Get method.

subscriberListData, err := suprClient.SubscriberLists.Get(ctx, "_list_id_")

​
Get all lists

To get the data of all the lists created in your workspace, use suprClient.SubscriberLists.GetAll  method

allSubscriberList, err := suprClient.SubscriberLists.GetAll(ctx, &suprsend.SubscriberListAllOptions) // default limit 20
allSubscriberList, err := suprClient.SubscriberLists.GetAll(ctx, &suprsend.SubscriberListAllOptions{Limit: 10, Offset: 0}) // max limit 1000

​
Add subscribers to the list

Use suprClient.SubscriberLists.Add to add list subscribers. There is no limit to the number of subscribers that you can add to a list.

addDistinctIds := []string{"distinct_id_1", "distinct_id_2"}
addResponse, err := suprClient.SubscriberLists.Add(ctx, "users-with-prepaid-vouchers-1", addDistinctIds)
if err != nil {
  log.Fatalln(err)
}
log.Println(addResponse)

​
Remove subscribers from the list

removeDistinctIds := []string{"distinct_id_1", "distinct_id_2"}
removeResponse, err := suprClient.SubscriberLists.Remove(ctx, "users-with-prepaid-vouchers-1", removeDistinctIds)
if err != nil {
  log.Fatalln(err)
}
log.Println(removeResponse)

​
Delete list

deleteListResp, err := suprClient.SubscriberLists.Delete(ctx, "users-with-prepaid-vouchers-1")
if err != nil {
  log.Fatalln(err)
}
log.Println("delete list resp: ", deleteListResp)

​
Replace users from the list

In case you want to refresh list with a new set of users completely, you can replace users by creating a draft version of the list and updating users in it.

1

Start Sync to create draft version of the list

This method will create a draft version of the list where you can add the new set of users to replace users.

// start sync
newVersion, err := suprClient.SubscriberLists.StartSync(ctx, "users-with-prepaid-vouchers-1")
if err != nil {
  log.Fatalln(err)
}
log.Println("start sync resp: ", newVersion)

versionId := newVersion.VersionId
2

Add Subscribers to draft list

You can use this method to add subscribers to List draft version created in Step 1. You’ll get version_id in start sync response.

// ================= Add users to a draft list (with versionId)
addDistinctIds := []string{"id-399999", "id-399998"}
addResponse, err := suprClient.SubscriberLists.AddToVersion(ctx, "users-with-prepaid-vouchers-1", versionId, addDistinctIds)
if err != nil {
  log.Fatalln(err)
}
log.Println("add to version resp:", addResponse)
3

Remove Subscribers from draft list

You can use this method to remove subscribers from List draft version created in Step 1. You’ll get version_id in start sync response.

// ================= remove users from a list
removeDistinctIds := []string{"distinct_id_1", "distinct_id_2"}
removeResponse, err := suprClient.SubscriberLists.RemoveFromVersion(ctx, "users-with-prepaid-vouchers-1", versionId, removeDistinctIds)
if err != nil {
  log.Fatalln(err)
}
log.Println("remove from version resp: ", removeResponse)
4

Finish Sync to make the draft version live

Once your subscribers are updated in the list, use this method to finish sync and make the draft version updated in above steps live.

// finish sync
finishSyncResp, err := suprClient.SubscriberLists.FinishSync(ctx, "users-with-prepaid-vouchers-1", versionId)
if err != nil {
  log.Fatalln(err)
}
log.Println("finish sync resp: ", finishSyncResp)

​
Delete Draft list

You can also delete draft list if it’s created by mistake.

deleteVersionResp, err := suprClient.SubscriberLists.DeleteVersion(ctx, "users-with-prepaid-vouchers-1", tempListVersion.VersionId)
if err != nil {
  log.Fatalln(err)
}
log.Println("delete version resp: ", deleteVersionResp)
