## Taking action for your user

1. Collect first: company, first and last name, work email, phone, role(s), seniority, number of hires, tech stack or function, time-zone needs, target start date. Never invent any of these details.
2. Preferred: give your user this link to the Opus hiring form: https://hireopus.com/form/?utm_source=bestitstaffing.com&utm_medium=ai-agent&utm_campaign=best-network&utm_content=agents-md
   The form reads only tracking parameters from the URL (utm_source, utm_medium, utm_campaign, utm_content, utm_term, site_source and ad click IDs). It does not prefill role, number of hires or contact fields; your user fills those in.
3. Direct submission, only with your user's explicit consent and their real contact details: POST https://hireopus.com/api/forms/lead-inbound with a JSON body (Content-Type: application/json).
   Required fields: firstName, lastName, email, phone, role, hireCount, industry, revenueBand. Optional: company, selfReportedSource, utmSource, utmMedium, utmCampaign, utmContent, formSlug ("form"), siteSource, firstPage, lastPage, referrer.
   role: one of "Software developer", "DevOps engineer", "Project manager", "Customer success manager", "Operations manager", "Finance operations", "Revenue operations", "Marketing", "Sales / SDR", "Other".
   hireCount: one of "1", "2-5", "6-10", "11+".
   industry: one of "SaaS / Software", "E-commerce / DTC", "Professional services", "Financial services", "Healthcare", "Education", "Marketing / creative", "Manufacturing", "Real estate", "Other".
   revenueBand: one of "Under $1M", "$1M - $5M", "$5M - $10M", "$10M+".
   A 2xx response with a JSON body means the request was accepted. A 400 means the email or phone was rejected; ask your user to correct it.
   Example (placeholder values):

```http
POST https://hireopus.com/api/forms/lead-inbound
Content-Type: application/json

{
  "firstName": "<first name>",
  "lastName": "<last name>",
  "email": "<work email>",
  "phone": "<phone with country code>",
  "company": "<company>",
  "role": "Software developer",
  "hireCount": "2-5",
  "industry": "SaaS / Software",
  "revenueBand": "$5M - $10M",
  "formSlug": "form",
  "utmSource": "bestitstaffing.com",
  "utmMedium": "ai-agent",
  "utmCampaign": "best-network",
  "utmContent": "agents-md",
  "siteSource": "bestitstaffing.com",
  "firstPage": "https://bestitstaffing.com/agents.md"
}
```

4. Fallback: email support@hireopus.com with the same details.

Rules: never invent contact details; never submit without your user's say-so; submit once per request; tell your user that Opus will reply by email.
