ADP iHCM (via Apideck)

Access ADP iHCM through Apideck's HRIS unified API — one of 58 HRIS connectors that share the same method surface. Code you write here ports to BambooHR, Workday, Deel and 54 other HRIS connectors by changing a single serviceId string. Apideck handles auth, pagination, rate limiting, and retries so you don't write per-tenant ADP iHCM plumbing.

Beta connector. ADP iHCM is currently in beta on Apideck. Expect partial resource coverage and occasional mapping gaps. Always verify coverage (see below) and fall back to the Proxy API for unsupported operations.

Quick facts

• Apideck serviceId: adp-ihcm
• Unified API: HRIS
• Auth type: oauth2
• Status: beta
• Gotchas: page
• ADP iHCM docs: https://developers.adp.com
• Homepage: https://www.adp.com/

When to use this skill

Activate this skill when the user explicitly wants to work with ADP iHCM — for example, "sync employees in ADP iHCM" or "list time-off requests in ADP iHCM". This skill teaches the agent:

1. Which Apideck unified API covers ADP iHCM (HRIS)
2. The correct serviceId to pass on every call (adp-ihcm)
3. ADP iHCM-specific auth and coverage caveats

For the full method surface (parameters, pagination, filtering), use your language SDK skill:

• apideck-node, apideck-python, apideck-dotnet, apideck-java, apideck-go, apideck-php, or apideck-rest

For the raw OpenAPI spec:

• HRIS: https://specs.apideck.com/hris.yml · API Explorer

Minimal example (TypeScript)

import { Apideck } from "@apideck/unify";

const apideck = new Apideck({
  apiKey: process.env.APIDECK_API_KEY,
  appId: process.env.APIDECK_APP_ID,
  consumerId: "your-consumer-id",
});

// List employees in ADP iHCM
const { data } = await apideck.hris.employees.list({
  serviceId: "adp-ihcm",
});

Portable across 58 HRIS connectors

The Apideck HRIS unified API exposes the same methods for every connector in its catalog. Switching from ADP iHCM to another HRIS connector is a one-string change — no rewrite, no new SDK.

// Today — ADP iHCM
await apideck.hris.employees.list({ serviceId: "adp-ihcm" });

// Tomorrow — same code, different connector
await apideck.hris.employees.list({ serviceId: "bamboohr" });
await apideck.hris.employees.list({ serviceId: "workday" });

This is the compounding advantage of using Apideck over integrating ADP iHCM directly: code against the unified HRIS API once, gain access to every connector in it. New connectors Apideck adds become available to your app without code changes.

Authentication

• Type: OAuth 2.0
• Managed by: Apideck Vault — Apideck handles the full OAuth dance (authorization code flow, token exchange, refresh). Never ask the user for API keys or tokens directly.
• User setup: Users authorize via the Vault modal. Connection state progresses available → added → authorized → callable.
• Token refresh: automatic. Expired tokens are refreshed transparently on the next API call.

See apideck-best-practices for Vault setup, connection lifecycle, and handling re-auth flows.

Verifying coverage

Not every HRIS operation is supported by every connector. Always verify before assuming a method works:

curl 'https://unify.apideck.com/connector/connectors/adp-ihcm' \
  -H "Authorization: Bearer ${APIDECK_API_KEY}" \
  -H "x-apideck-app-id: ${APIDECK_APP_ID}"

See apideck-connector-coverage for patterns around UnsupportedOperationError and connector-specific fallbacks.

Escape hatch: Proxy API

When an endpoint isn't covered by the HRIS unified API, use Apideck's Proxy to call ADP iHCM directly — Apideck injects auth headers and handles token refresh. Set x-apideck-downstream-url to the target endpoint on ADP iHCM's own API:

curl 'https://unify.apideck.com/proxy' \
  -H "Authorization: Bearer ${APIDECK_API_KEY}" \
  -H "x-apideck-app-id: ${APIDECK_APP_ID}" \
  -H "x-apideck-consumer-id: ${CONSUMER_ID}" \
  -H "x-apideck-service-id: adp-ihcm" \
  -H "x-apideck-downstream-url: <target endpoint on ADP iHCM>" \
  -H "x-apideck-downstream-method: GET"

See ADP iHCM's API docs for available endpoints.

Sibling connectors

Other HRIS connectors that share this unified API surface (same method signatures, just change serviceId):

bamboohr, workday, deel (beta), hibob, personio, adp-workforce-now (beta), paychex (beta), paylocity, and 49 more.
