Quickstart Guide

1. Prerequisites

What	Why
Clasp API key	Used as a Bearer token from your backend to call the API and mint component links.

Never expose your long‑lived API key in the browser.
All API calls that use the Bearer key should originate server‑side.

2. Create an employer

POST /employers
Authorization: Bearer $CLASP_API_KEY
Content-Type: application/json

{
  "legal_name": "Example Legal Name",
  "trade_name": "Example Trade Name",
  "external_id": "payroll_provider_company_id",
  "email": "company@domain.com",
  "address": {
    "line1": "1600 Pennsylvania Ave",
    "city": "Washington",
    "state": "DC",
    "zip_code": "20500"
  }
}

The response includes an id such as er_123. Persist this for future calls.

3. Create an employee (members)

POST /members
Authorization: Bearer $CLASP_API_KEY
Content-Type: application/json

{
  "first_name": "Jane",
  "last_name": "Doe",
  "dob": "1990-05-16",
  "ssn": "123456789",

  "employer": "er_123",
  "hire_date": "2024-01-08",
  "hours_worked": 40,
  "pay_frequency": "biweekly"
}

Save the returned member id (e.g., mem_456).

4. Create a group structure

POST /groups
Authorization: Bearer $CLASP_API_KEY
Content-Type: application/json

{
  "group_number": "1324234",
  "carrier": "carr_xOvpBqHA75scQCtcHNfLS",
