## Which one, for what

### Employment Hero Payroll (D)

Good for: An agent acting for an employer or bureau already on Employment Hero Payroll in Australia, New Zealand, the United Kingdom, Singapore or Malaysia, and white label partners who create businesses through the brand endpoints.

Ahead on:
- Reliability, 65 against 58

Watch for: An API key carries the whole access of the user who generated it. No per-key scopes were found

### Gusto (B)

Good for: A software platform that wants to run US payroll for its own customers and can pass Gusto's partner reviews.

Ahead on:
- Schema & documentation, 86 against 51
- Agent ergonomics, 82 against 53
- Security & auth, 60 against 46
- Payments & pricing, 15 against 10
- Maintenance & community, 76 against 68

Watch for: Production keys need commercial, security and implementation reviews with Gusto's partnerships team, and the docs say not all use cases are supported

## Verdicts

**Employment Hero Payroll.** Five public Swagger 2.0 files describe 660 to 821 operations per region, and any payroll user can generate an API key without a partner review. The key carries its user's whole access, no idempotency keys or API changelog were found, and the only official client is for .NET.

**Gusto.** This listing covers the Embedded Payroll API. Every reference page carries an OpenAPI 3.1 definition, payroll is calculated as a preview before submission, and each API version gets 12 months of deprecation support. Production needs commercial and security approval, no price was readable, and the status page lists 11 incidents between 14 July and 5 October 2026, five marked major.

## Before you call either

### Employment Hero Payroll

1. Send the API key as the Basic auth username with a blank password, for example `curl -u {api_key}: https://api.yourpayroll.com.au/api/v2/user`
2. Pick the Swagger file for the business's region (`swagger-au.json`, `swagger-nz.json`, `swagger-uk.json`, `swagger-sg.json`, `swagger-my.json`). Paths and models differ by region
3. Stay under 5 requests a second per key and IP address. A 429 answered our test with `retry-after: 1`
4. Page lists with `$skip` and `$top` (100 at most). Filter property names are capitalised, unlike the camelCase JSON
5. Read `GET /api/v2/business/{businessId}/payrun/{payRunId}/warnings` before `POST .../finalise`. Finalise can lodge with the tax office and publish pay slips in the same call

### Gusto

1. Develop against https://api.gusto-demo.com. Production at https://api.gusto.com needs keys Gusto issues after its reviews
2. Send `X-Gusto-API-Version: 2026-06-15` on every call. Without it the application's minimum version applies
3. Send the resource's current `version` with every PUT, and only the fields to change. A stale version returns 409
4. Calculate and submit return 202. Poll GET on the payroll until `calculated_at` is set or the status is processed, and read `submission_blockers` first
5. For a company already on Gusto, the Embedded API is the wrong route. Use the Gusto CLI or the MCP server at https://mcp.api.gusto.com, which draft payroll but can't submit it
