Registration

After an Advisor sends an invitation, the individual user completes a guided onboarding flow — covering invitation acceptance, agreements, W9, security questions, phone OTP, and KYC submission — to activate their accounts.

Steps

Step 1: Validate the invitation token

GET /branches/public/v1/common/invites/check?token=<invite_token>

• Auth: None
• On success (200): Returns role and customerUid — proceed to session creation.
• On error (400): Show "Invitation expired or not found."

{
  "data": {
    "role": "individual",
    "customerUid": "a1b2c3d4-0000-0000-0000-000000000001"
  }
}

Create a scoped session (before Step 3)

Use the customerUid from Step 1 to open a session for this user:

POST /entrypoint/org/v1/sessions

{
  "clientId":     "<your-client-id>",
  "clientSecret": "<your-client-secret>",
  "customerUid":  "<customerUid from Step 1>"
}

{
  "data": {
    "sessionId": "4bdfca21-461e-45a2-9d26-64f4176267c7",
    "expiresAt": "2026-06-24T12:00:00Z"
  }
}

Include these headers on every request from Step 3 onward:

X-Session-Id: <sessionId>
X-Client-Id:  <clientId>

Step 2: Fetch platform agreements

GET /branches/public/v1/common/agreements

• Auth: None
• Display each agreement's title and content. Require the user to acknowledge each one before continuing.

Step 3: Accept the invitation

POST /branches/public/v1/individual/invites/accept?token=<invite_token>

• Auth: Session headers
• No request body required.

Path differs per user type:

• Individual: /branches/public/v1/individual/invites/accept
• Business Owner: /branches/public/v1/businessowner/invites/accept
• Operator: /branches/public/v1/operator/invites/accept

Step 4: Review W9 terms

GET /branches/private/v1/limited/w9/terms

• Auth: Session headers
• Display the W9 tax certification text. Record the timestamp of user acceptance for Step 9.

Step 5: List security questions

GET /users/private/v1/limited/security-questions

• Auth: Session headers
• Present questions for the user to choose from and answer.

Step 6: Submit security answers

POST /users/private/v1/limited/security-questions/answers

{
  "answers": [
    { "questionId": 1, "answer": "Seattle" },
    { "questionId": 5, "answer": "Buddy" },
    { "questionId": 9, "answer": "Blue" }
  ]
}

• Auth: Session headers. Exactly 3 distinct question IDs required.

Step 7: Send phone OTP

POST /users/private/v1/limited/generate-new-phone-code

• Auth: Session headers
• Triggers an SMS to the phone number registered during invitation.

Step 8: Verify phone OTP

PUT /users/private/v1/limited/check-phone-code

{ "code": "ABC12" }

{
  "dateOfBirth": "03/20/1990",
  "socialSecurityNumber": "987-65-4321",
  "usCitizenshipStatus": "Citizen",
  "address": {
    "address": "123 Main Street",
    "city": "New York",
    "state": "NY",
    "zipCode": "10001",
    "country": "USA"
  },
  "w9": {
    "isSubjectToBackupWithholding": false,
