Verdicts

Check

Graded as embedded payroll through a partner API key, not access to an existing employer's payroll account. The API has idempotency keys on writes, a required preview before approval and queryable request logs. No price is public, a sandbox key comes through Check's sales team, and one API key carries the whole partner account.

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.

Before you call either

Check

  1. Use https://sandbox.checkhq.com with the sandbox key and https://api.checkhq.com with the production key. A key is not valid across environments
  2. Preview a payroll before approving it, then pass preview_started_at to POST /payrolls/{id}/approve so a stale preview fails with 409
  3. Send X-Idempotency-Key on every write. Keys expire after 24 hours, so list the resource before retrying later than that
  4. On 429 wait for Retry-After. The limit is 10 requests a second in sandbox and for partners paying fewer than 1,000 payees a month, with 100 concurrent requests
  5. Connect the MCP server with ?read_only=true or X-MCP-Readonly: true unless writes are intended. In production, approving a payroll moves money

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
