Automatic Data Processing (ADP) · Rate Limits

Automatic Data Processing Rate Limits

Rate limit posture for the ADP HCM API surface. ADP does not publicly document per-second or per-minute limits; throttling decisions are made by ADP based on the partner contract and the underlying ADP product (Workforce Now, RUN, Vantage). Sustained partner traffic is shaped by ADP's shared-tenant architecture and may be increased via partner support.

Automatic Data Processing Rate Limits is the machine-readable rate-limit profile for Automatic Data Processing (ADP) on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 1 rate-limit definition, measuring varies.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled and serviceUnavailable.

Tagged areas include HCM, Human Capital Management, HR, Payroll, and Benefits.

Limits

ADP Marketplace Partner Default partner-application

see ADP partner agreement
ADP does not publish numeric per-second or per-minute limits. Apply exponential backoff with jitter and honor Retry-After.

Policies

Backoff Strategy
Implement exponential backoff with jitter. Honor the Retry-After header when present on 429 / 503 responses.
Consent-Scoped Access
API calls are scoped to customers who have granted consent to the partner application through ADP's Marketplace consent flow. Revocation immediately removes access to that customer's data.
Partner Support Path
Production rate limit increases are requested through the ADP Marketplace partner manager rather than a self-serve console.
