Workday's agents

Self-Service Agent actions per employee a month

Averaged over all employees, users or not.

What counts?

Each time the agent does a task for an employee, such as checking a PTO balance, requesting a day off or updating an address, it uses actions. Each action is 1 credit, and a more complex request can take several.

Example levels, not Workday definitions: 1 a month is light, an occasional balance check. 2 is typical, a couple of requests a month. 5 is heavy, frequent requests and manager approvals.

Example: 1,000 employees × 2 actions = 2,000 credits a month, 24,000 a year.

Workday's website lists 5 credits for autonomous tasks; the rate card says 1, and we use the rate card.

Your estimate

180,000 credits to buy

Range: 60,000 to 540,000 credits to buy at 1 to 5 Self-Service Agent actions per employee a month.

About $18,000 a year at $0.10 a credit. At $0.01 a credit: $1,800.

Your 60,000 complimentary (free) credits last about 3 months at an even burn.

The meters

How agents use Flex Credits

The path an agent takes into Workday decides which meter applies.

Two free buckets: an API allowance counted in calls, and complimentary credits counted in credits. Only API calls get an allowance; agents use credits from the first unit.

How an agent reaches Workday

  • Workday's own agents

    Priced per action or unit on the rate card.

  • Custom agents in Workday Extend

    1 to 3 credits per invocation, plus their Agent-Ready Tool calls at 5 to 25 credits per 100.

  • Agents built elsewhere

    • Through Workday's Agent-Ready Tools (MCP): 10 to 50 credits per 100 calls.
    • Through Workday's APIs (REST, SOAP, RaaS or WQL), directly or through a connector such as StackOne's: draws on your API allowance first, then 0.6 credits per 100 calls (60 credits per 10,000).

* Per analysts' reading of a policy Workday hasn't published. ** Agents built outside Workday: 10 credits per 100 reads, 50 credits per 100 calls that change data (our reading: the rate card's "non-Custom Agents" rate applies to them). Custom Extend agents: 5 to 25 credits per 100 calls.

Agent-Ready Tools and custom agents need Workday Extend Professional. Source: Workday Flex Credits rate card, 9 October 2026.

The rate card has two other yearly entitlements outside these meters: 432 minutes of Sana Learn narration and 50,000 Developer Agent invocations (rate card footnotes 1 and 3).

Keep calls light

For agents you build or buy, how they call Workday sets the bill

An agent that re-reads everything uses more calls and more tokens than it needs. These patterns are the usual cause:

  • Full re-syncs where a change feed would do
  • 100 records a page when 999 is allowed
  • One call per record instead of one report run
  • Full SOAP worker records sent into the model's context
  • Retry loops that turn 4 calls into 10

Where StackOne fits

Agent calls through Workday's APIs share your yearly allowance with every integration. StackOne's Workday connector is built to help agents and integrations make fewer, lighter calls, so they use less of that allowance.

Agents that use StackOne's Workday connector call Workday's APIs, so their calls draw on your API allowance, not on Agent-Ready Tool credits.
