Deduction write, in detail
For benefits, HSA/FSA and 401(k) integrations. 10 of 10 fields are unverified — no public source states the answer. Compare every system on the deduction write detail page.
| Field | Value | Conf | Note — and what a correct answer needed |
|---|---|---|---|
| Deduction read | Unverified | U | No public developer portal, API reference, sandbox or OpenAPI specification was located. Third parties state partner integrations rely on privately shared documentation and API access is not self-serve. |
| Deduction write | Unverified | U | No public specification. Third parties state most production integration paths run through Finch or Merge, and that bulk data still moves by CSV or SFTP — which, if accurate, means the effective method is grade C or D rather than an API. |
| Pre-tax vs post-tax at write | Unverified | U | No public specification. |
| Amount vs percent | Unverified | U | No public specification. |
| Effective dating | Unverified | U | No public specification. |
| Retro adjustment | Unverified | U | No public specification. |
| Employer contribution | Unverified | U | No public specification. |
| Code taxonomy shape | Unverified | U | No public specification. |
