Users

Stream allows you to store user information and embed them inside activities or use them for personalization. When stored in activities, users are automatically enriched by Stream.

const client = stream.connect(
  "{{ api_key }}",
  "{{ feed_token }}",
  "{{ app_id }}",
);

// ensure the user data is stored on Stream
await client.setUser({
  name: "John Doe",
  occupation: "Software Engineer",
  gender: "male",
});

# The Python API client exposes users methods on client.users
# when adding reactions, collections or reading feeds with enrichment
# you can provide `user_id` as an argument

# The Ruby API client exposes user method on client.users
# when adding reactions, collections or reading feeds with enrichment
# you can provide `:user_id` as an argument

// The PHP API client exposes users methods on $client->users()
// when adding reactions, collections or reading feeds with enrichment
// you can provide `$user_id` as argument

// Java API client exposes users methods on client.user object
// when adding reactions, collections you can provide `userID` as argument

# The Go API client exposes users methods on Client.Users.
# When adding reactions, collections or reading feeds with enrichment
# you can provide `user_id` as an argument

Adding Users

This endpoint allows you to insert a new user.

Name	Type	Description
id	string	The unique identifier for the new user (eg. username, user id, etc.). The value is restricted to alphanumeric characters, dashes and underscore symbols.
data	object	The data related to the user.

// create a new user, if the user already exist an error is returned
const userData = new Dictionary<string, object>
{
  {"name", "John Doe" },
  {"occupation", "Software Engineer"},
  {"gender", "male"},
};

await client.Users.AddAsync("john-doe", userData);

// get or create a new user, if the user already exist the user is returned
await client.Users.AddAsync("john-doe", userData, true);

// create a new user, if the user already exist an error is returned
client.user("john-doe").create({
  name: "John Doe",
  occupation: "Software Engineer",
  gender: "male",
});

// get or create a new user, if the user already exist the user is returned
client.user("john-doe").getOrCreate({
  name: "John Doe",
  occupation: "Software Engineer",
  gender: "male",
});

# create a new user, if the user already exist an error is returned
client.users.add(
  "john-doe",
  {"name": "John Doe", "occupation": "Software Engineer", "gender": "male"},
)

# get or create a new user, if the user already exist the user is returned
client.users.add(
  "john-doe",
  {"name": "John Doe", "occupation": "Software Engineer", "gender": "male"},
  get_or_create=True,
)

# create a new user, if the user already exists, an error is returned
client.users.add(
  "john-doe",
  :data => {:name => "John Doe", :occupation => "Software Engineer", :gender => "male"},
)

# get or create a new user, if the user already exists, the user is returned
client.users.add(
  "john-doe",
  :data => {:name => "John Doe", :occupation => "Software Engineer", :gender => "male"},
  :get_or_create => true,
)

// create a new user with the name in userdata
$user = $client->users()->add('42', array('name' => 'Arthur Dent'));
// get OR create the user
$user = $client->users()->add('42', array('name' => 'Arthur Dent'), true);

// create a new user, if the user already exist an error is returned
client.user("john-doe").create(new Data()
    .set("name", "John Doe")
    .set("occupation", "Software Engineer")
    .set("gender", "male")).join();

// get or create a new user, if the user already exist the user is returned

    .set("name", "John Doe")
    .set("occupation", "Software Engineer")
    .set("gender", "male")).join();

// create a new user, if the user already exist an error is returned
	userData := stream.User{
		ID: "123",
		Data: map[string]any{
			"name":    "John Doe",
			"occupation": "Software Engineer",
			"gender":   "male",
		},
	}
	resp, err := client.Users().Add(context.TODO(), userData, false)
	if err != nil {
		panic(err)
	}

	// get or create a new user, if the user already exist the user is returned
	resp, err := client.Users().Add(context.TODO(), userData, true)
	if err != nil {
		panic(err)
	}

The size of a user object can not exceed 10kB

Retrieving Users

The retrieving users endpoint allows you to retrieve a user by their ID.

await client.Users.GetAsync("123");

client.user("123").get();

client.users.get("123")

client.users.get("123")

$client->users()->get('42');

client.user("123").get().join();

resp, err := client.Users().Get(context.TODO(), "123")
	if err != nil {
		panic(err)
	}

Removing Users

The delete endpoint removes a user by their ID.

await client.Users.DeleteAsync("123")

client.user("123").delete();

client.users.delete("123")

client.users.delete("123")

$client-&gt;users()-&gt;delete('42');

client.user("123").delete().join();

resp, err := client.Users().Delete(context.TODO(), "123")
	if err != nil {
		panic(err)
	}

When you delete a user it will be converted to a missing reference and throw an error when enriching.

Updating Users

This endpoint allows you to update a user by their ID.

Parameters

name	type	description	default	optional
id	string	The ID of the user to update	-
data	object	The data related to the user	-

var userData = new Dictionary<string, object>
{
  {"name", "Jane Doe" },
  {"occupation", "Software Engineer"},
  {"gender", "female"},
};
await client.Users.UpdateAsync("123", userData)

client.user("123").update({
  name: "Jane Doe",
  occupation: "Software Engineer",
  gender: "female",
});

client.users.update("123",
  {"name": "Jane Doe", "occupation": "Software Engineer", "gender": "female"}
)

client.users.update("123",
  :data => {:name => "Jane Doe", :occupation => "Software Engineer", :gender => "female"}
)

$user = $client-&gt;users()-&gt;update('42', array('name' =&gt; 'Arthur Dent');

client.user("123").update(new Data()
    .set("name", "Jane Doe")
    .set("occupation", "Software Engineer")
    .set("gender", "female")).join();

data := map[string]any{
		"name":    "John Doe",
		"occupation": "Software Engineer",
		"gender":   "female",
	}
	resp, err := client.Users().Update(context.TODO(), "123", data)
	if err != nil {
		panic(err)
	}
