Users & Tokens

Creating users

When creating users, there are a few important things to keep in mind:

  • The id field is mandatory, in most cases you want this to be the same ID you use on your database.
  • The role field is optional, by default it is set to user but you can specify any existing role.
  • Custom data can be added to users in the custom field.
  • name and image are optional and handled by all SDKs automatically to render users.
const newUser: UserRequest = {
  id: 'user-id',
  role: 'user',
  custom: {
    color: 'red',
  },
  name: 'This is a test user',
  image: 'link/to/profile/image',
};
await client.upsertUsers([newUser]);

Updating users

You can update users in two ways:

  • Replace updates: replace the entire user object with the one provided to the API call
  • Partial update: choose which fields you want to change
const user: UserRequest = {
  id: 'userid',
  role: 'user',
  custom: {
    color: 'blue',
  },
  name: 'This is a test user',
  image: 'link/to/profile/image',
};
client.upsertUsers([user]);

// or
client.updateUsersPartial({
  users: [
    {
      id: user.id,
      set: {
        'new-field': 'value',
      },
      unset: ['name'],
    },
  ],
});

Anonymous users

Anonymous users are users that are not authenticated. It’s common to use this for watching a livestream or similar where you aren’t authenticated. Anonymous users can be connected using client-side SDKs. Anonymous users are not counted toward your MAU.

Guest users

Guest users are temporary user accounts. You can use it to temporarily give someone a name and image when joining a call. Guest users can be created client-side. Guest users are counted towards your MAU usage.

Deactivating and deleting users

Depending on your use-case, you can choose to delete users or de-activating them. There are some differences between these two approach.

Deactivating users:

  • the user will not be allowed to perform API requests / connect
  • user data is retained on Stream’s side and returned from API
  • deactivated users can be re-activated

Deleting users:

  • the user will no longer be able to perform API requests / connect
  • the user is deleted and by default not returned from API
  • all data from the user is marked as deleted
  • by default the data is retained and “soft” deleted, you can optionally request hard deletion
  • deletion is not reversible

Note: Both deletion and deactivation are performed asynchronously by Stream API. A task ID is returned and you can use that to check the status of its processing.

Deactivating users

client.deactivateUser({
  user_id: '<id>',
});

// reactivate
client.reactivateUsers({
  user_ids: ['<id>'],
});

// deactivating users in bulk is performed asynchronously
const deactivateResponse = client.deactivateUsers({
  user_ids: ['<id1>', '<id2>'...],
});

Deactivating users in bulk can take some time, this is how you can check the progress:

// Example of monitoring the status of an async task
// The logic is same for all async tasks
const response = await client.<async operation>();

// you need to poll this endpoint
const taskResponse = await client.getTask({id: response.task_id})

console.log(taskResponse.status === 'completed');

For more information, please refer to the async operations guide

Deleting users

client.deleteUsers({ user_ids: ["<id>"] });

//restore
client.restoreUsers({ user_ids: ["<id>"] });

The delete users endpoints supports the following parameters to control which data needs to be deleted and how. By default users and their data are soft-deleted.

NameTypeDescriptionOptional
userEnum (soft, pruning, hard)- Soft: marks user as deleted and retains all user data.
- Pruning: marks user as deleted and nullifies user information.
- Hard: deletes user completely - this requires hard option for messages and conversation as well.
Yes
conversationsEnum (soft, hard)- Soft: marks all conversation channels as deleted (same effect as Delete Channels with ‘hard’ option disabled).
- Hard: deletes channel and all its data completely including messages (same effect as Delete Channels with ‘hard’ option enabled).
Yes
messagesEnum (soft, pruning, hard)- Soft: marks all user messages as deleted without removing any related message data.
- Pruning: marks all user messages as deleted, nullifies message information and removes some message data such as reactions and flags.
- Hard: deletes messages completely with all related information.
Yes
new_channel_owner_idstringChannels owned by hard-deleted users will be transferred to this userID. If you doesn’t provide a value, the channel owner will have a system generated ID like delete-user-8219f6578a7395gYes
callsEnum (soft, hard)- Soft: marks calls and related data as deleted.
- Hard: deletes calls and related data completely
Note that this applies only to 1:1 calls, not group calls
Yes

Deleting and restoring users in bulk can take some time, this is how you can check the progress:

// Example of monitoring the status of an async task
// The logic is same for all async tasks
const response = await client.<async operation>();

// you need to poll this endpoint
const taskResponse = await client.getTask({id: response.task_id})

console.log(taskResponse.status === 'completed');

User tokens

Stream uses JWT (JSON Web Tokens) to authenticate users, enabling them to log in. Knowing whether a user is authorized to perform certain actions is managed separately via a role-based permissions system. Tokens need to be generated server-side.

You can optionally provide an expiration time.

const userId = "john";
// validity is optional, in this case we set it to 1 day
const validity = 24 * 60 * 60;
client.generateUserToken({ user_id: userId, validity_in_seconds: validity });

You need to provide the generated tokens to the client SDKs. Stream SDKs accept a token provider, that can be called to retrieve and renew tokens. You need to implement the token provider in your own application, this is usually an HTTP endpoint.

Call tokens

Call tokens contain a list of call IDs. When a user utilizes a call token, they will automatically be assigned the membership role for all the calls specified in the token’s claims. Additionally, the token may optionally include alternative roles, such as admin or moderator.

const user_id = "john";
// validity is optional (by default the token is valid for an hour)
const validity_in_seconds = 60 * 60;

const call_cids = ["default:call1", "livestream:call2"];

client.generateCallToken({ user_id, call_cids, validity_in_seconds });

// Optionally provide a role for the call(s)
client.generateCallToken({ user_id, call_cids, role: "admin" });

Note: Call tokens are designed to grant additional access, not restrict it. Most call types let regular users join calls. If all users can access any call, call tokens won’t change this. Remove call access from the user role and grant it to specific members instead.
