Verdicts
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.
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
Everee
- Send two headers on every call,
authorization: basic <token>andx-everee-tenant-id. Base64-encode a token that starts withsk_first. - Derive each payable's
externalIdfrom stable data, never a timestamp or UUID, so a retried create is rejected instead of paying twice. - For contractors, call POST
/integration/v1/payables/payment-requestafter all payable items are sent and before admins approve. Without it contractors aren't paid. - Send hourly wages through the Timesheets API, not Payables, and assign
workLocationIdso tax is worked out for the right jurisdiction. - 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.
Salsa
- 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
- Call POST /payroll-runs/preview before creating a run, then confirm the PENDING run in a separate call. Confirming starts the employer debit
- Send your own externalId on every create. A repeat returns a uniqueness error, which is the only duplicate protection
- Make sure externalId values are unique across all employers, since each entity type has one namespace
- Mint a user token with the lowest role and the fewest employerIds the task needs, and keep the partner token on the server
