Configure Finch Connect for a benefits platform and write 401k contribution elections to multiple payroll providers

Steps

1. Embed the Finch Connect button or SDK in your benefits platform UI; configure the Connect session with the deductions product scope to request write access
2. After the employer completes the Connect flow, store the access_token securely — it represents that employer's consent to write payroll data
3. Create the 401k benefit at the company level: POST /employer/benefits with benefit_type set to the appropriate 401k code and contribution details
4. Enroll each participating employee: POST /employer/benefits/{benefit_id}/individuals with each employee's individual_id and their elected pre-tax and/or Roth contribution amounts
5. Verify enrollments before the payroll close date with GET /employer/benefits/{benefit_id}/individuals; check each record's enrollment status field
6. After each payroll run, retrieve contribution actuals and reconcile against elected amounts; report discrepancies to both the employer and the retirement recordkeeper
