How SuprSend identifies a User

SuprSend identifies users with immutable distinct_id. It’s best to map the same identifier in your DB with distinct_id in SuprSend. Do not use identifiers that can be changed like email or phone number. You can view synced users by searching distinct_id on Users page.

​
Create User

To create a new user or to update an existing user, you’ll have to fetch user instance. Call supr_client.user.get_instance to instantiate user object. 
const user = supr_client.user.get_instance("_distinct_id_"); // create user instance

// user methods mentioned in this docs can be attached to user instance if needed

const response = user.save() // IMP: trigger request
response.then((res) => console.log("response", res));

​
Edit User

To Edit user, you need to first fetch user instance, call all the update methods and save changes using user.save() method. 
// Fetch user instance
const user = supr_client.users.get_edit_instance("_distinct_id_");

// Call user update methods
user.set_timezone("America/Los_Angeles");
user.set("name", "John Doe");

// Save Changes
const response = user.save(); // IMP: trigger request
response.then((res) => console.log("response", res));
Here’s a list of all edit methods:
After calling add*/remove*/unset methods, don’t forget to call the user.save() request. the changes will be sent to SuprSend only after calling this method.

​
Bulk API for updating multiple user profiles

To update multiple user profiles use Bulk API. There isn’t any limit on number-of-records that can be added to bulk_users instance. Use append() on bulk_users instance to add however-many-records to call in bulk. 
const { Suprsend } = require("@suprsend/node-sdk");

const supr_client = new Suprsend("workspace_key", "workspace_secret");

const bulk_ins = supr_client.bulk_users.new_instance()

// user1 instance
const user1 = supr_client.user.get_instance("_distinct_id_1")
user1.add_email("u1@example.com")
user1.set_preferred_language("en")

// user2 instance
const user2 = supr_client.user.get_instance("_distinct_id_2")
user2.remove_email("u2@example.com")

//append users instance to bulk instance
bulk_ins.append(user1)
bulk_ins.append(user2)
// OR
bulk_ins.append(user1, user2)

 // trigger request
const response = bulk_ins.save()
response.then((res) => console.log("response", res));

​
Get user details

const response = await supr_client.users.get(_distinct_id_);

​
Delete user

const response = await supr_client.users.delete(_distinct_id_);

​
Get list of objects subscribed by user

const response = await supr_client.users.get_objects_subscribed_to(_distinct_id_, {limit:20});
You can pass optional query parameters - limit,before,after.

​
Get lists subscribed by user

const response = await supr_client.users.get_lists_subscribed_to(_distinct_id_, {limit:20});
You can pass optional query parameters - limit,before,after.
