## 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.

**Salsa.** Salsa is reached as an embedded-payroll partner, not through an employer's existing payroll account. The REST API has a public OpenAPI 3.1 spec with 123 operations, a payroll preview, a separate confirm step and short-lived user tokens limited by role. Access starts with a sales conversation, and no public price, self-serve sandbox, status page or API changelog was found.

## 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

### Salsa

1. Use the sandbox token against https://api.sandbox.salsa.dev and the production token against https://api.salsa.dev. Each environment has its own token
2. Call POST /payroll-runs/preview before creating a run, then confirm the PENDING run in a separate call. Confirming starts the employer debit
3. Send your own externalId on every create. A repeat returns a uniqueness error, which is the only duplicate protection
4. Make sure externalId values are unique across all employers, since each entity type has one namespace
5. Mint a user token with the lowest role and the fewest employerIds the task needs, and keep the partner token on the server
