Argyle vs Everee

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.

Everee

Everee's API tokens are created in the admin portal of each company instance, and payments wait for a payroll admin's approval unless auto-approval is arranged. The API has no preview or approval endpoint, no single OpenAPI file, no SDK and no changelog, and a company instance starts with a sales call.

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

Everee

1. Send two headers on every call, authorization: basic <token> and x-everee-tenant-id. Base64-encode a token that starts with sk_ first.
2. Derive each payable's externalId from stable data, never a timestamp or UUID, so a retried create is rejected instead of paying twice.
3. For contractors, call POST /integration/v1/payables/payment-request after all payable items are sent and before admins approve. Without it contractors aren't paid.
4. Send hourly wages through the Timesheets API, not Payables, and assign workLocationId so tax is worked out for the right jurisdiction.
5. Don't expect the API to move money alone. Tell the user a payroll admin must approve in the portal unless auto-approval is enabled, and read Everee's terms on automated access first.
