Argyle vs Worklio

Argyle

Graded on the REST API. One OpenAPI file covers 91 operations, llms.txt indexes Markdown docs, and a Sandbox with sample users comes with a Console sign-up. Every payroll connection needs the worker to sign in through Link. No prices are published, no idempotency keys were found, and API keys carry no per-key scopes.

Worklio

Worklio documents 853 REST operations with an OpenAPI fragment on every reference page, and a developer can register for the sandbox without a sales call. No rate limits or public SDK were found, the status page is password protected, and the payroll guide tells callers to treat an HTTP 500 as the signal to finalise.

Argyle

1. Send HTTP Basic auth with api_key_id as the username and api_key_secret as the password. Sandbox keys fail with 401 on Production and the reverse
2. Create the user with POST /v2/users and an external_id, then look it up by external_id before retrying. No idempotency key was found
3. Do not read data straight after an account connects. Wait for the account and data webhooks, or for the verification status, before fetching records
4. Follow the full URL in next when paging. Do not build cursor values or fetch pages in parallel. limit defaults to 10 and stops at 200
5. Stay under 50 requests a second. On 429, queue the request and retry later, not at once
6. Treat DELETE /v2/users/{id} as permanent. It removes every resource tied to that user, with no confirmation step

Worklio

1. Send api-version: 2.0 on /wep calls. The reference marks the header as required
2. Get a token from POST https://api.worklio.com/connect/token with the password grant and scope api. It lasts 24 hours, so fetch a new one daily
3. Run payroll as start, next until it answers 500 with "Next step operation is not allowed", then finalize. Don't treat that 500 as a failure
4. Don't retry bonus, off-cycle, void or termination payroll starts blindly. The reference says those calls are not idempotent
5. Most /wep list endpoints return the whole result set. Paging, filter and sort work only under /api/public, and a DataToken expires after 60 seconds
