User Identification

Open in workspace →

User identification lets you associate messenger conversations with known users in your application.

Anonymous visitors

For visitors who aren’t logged in, set the user to anonymous:

promptify.setUser({ id: null });

Anonymous sessions are tracked via browser cookies.

Identified users (without verification)

Pass user data directly when JWT verification is not required:

promptify.setUser({
  id: "user-123",
  email: "jane@example.com",
  name: "Jane Doe",
  avatarUrl: "https://example.com/avatar.jpg",
  attrs: {
    plan: "pro",
    active: true,
  },
  organizations: [{ id: "org-456", name: "Acme Corp", attrs: { industry: "SaaS" } }],
});

User data fields

Field	Type	Required	Description
id	string | number | null	yes	Unique user ID, or null for anonymous
email	string	no	Email address
name	string	no	Display name
avatarUrl	string	no	Profile image URL (must be https://)
attrs	object	no	Custom key-value pairs (max 50)
organizations	array	no	Organizations the user belongs to (max 10)

User and organization data appears in the user details panel in the inbox.

Organization fields

Each entry in the organizations array accepts the following fields:

Field	Type	Required	Description
id	string | number	yes	Unique organization identifier
name	string	yes	Organization display name
attrs	object	no	Custom key-value pairs (max 50)

Organizations are deduplicated by their id. A user can belong to up to 10 organizations.

The organizations array is always treated as the complete list. If you previously included an organization and omit it in a subsequent setUser() call, the user will be removed from that organization.

Identified users (with verification)

For secure identification, sign a JWT on your server and pass it to the widget:

promptify.setUser({ jwt: "eyJ..." });

Generating the JWT

1. Generate an asymmetric key pair using one of the supported algorithms: EdDSA, ES256, PS256, or RS256.
2. Upload the public key (SPKI format) in Settings > Messenger > Security.
3. Sign a JWT on your server with the private key:

import { SignJWT } from "jose";

let jwt = await new SignJWT({
  id: "user-123",
  email: "jane@example.com",
  name: "Jane Doe",
})
  .setProtectedHeader({ alg: "EdDSA" })
  .setExpirationTime("5m")
  .sign(privateKey);

4. Pass the signed JWT to the widget from your frontend.

The JWT payload uses the same user data fields as the unsigned setUser call. The exp claim is required. You can optionally include a jti claim for one-time-use token enforcement.

When replacing a public key, the previous key remains valid for 2 hours to prevent disruption.
