Changelog

1.0.0

Initial release.

Added

• Modern REST API: Tipalti.Payees, Tipalti.Invoices, Tipalti.Payments — full CRUD/list/stream coverage, OAuth2 client-credentials auth with automatic token caching and refresh (Tipalti.Auth.TokenServer).
• Legacy SOAP API: Tipalti.SOAP.Payee (21 operations) and Tipalti.SOAP.Payer (24 operations), covering the full Payee/Payer Functions surface, with automatic HMAC-SHA256 request signing (Tipalti.SOAP.Signature) and XML fault parsing.
• Procurement REST API: Tipalti.Procurement.PurchaseOrders (list/update) and Tipalti.Procurement.Employees (full 3-step CSV upload/import flow).
• Tipalti.Config for credential/environment management across all three API families.
• Tipalti.Error and 6 typed exception subclasses (AuthenticationError, ValidationError, APIError, RateLimitError, NetworkError, SOAPFaultError).
• Tipalti.HTTP: transport built on OTP's :httpc/:ssl (no external HTTP client dependency), with exponential backoff + full jitter retries and TLS verification via :public_key.cacerts_get/0.
• Tipalti.Pagination: generic Stream-based auto-pagination, used by every REST resource's stream/2.
• Tipalti.RateLimiter: optional token-bucket rate limiter for high-throughput Procurement API usage.
• Tipalti.Webhook: IPN notification parsing.
• Tipalti.Telemetry: :telemetry span instrumentation on every request.
• Every read/write function has a raising ! counterpart.
• mix credo --strict: 0 issues (312 functions analyzed). mix dialyzer: 0 errors. Both credo and dialyxir (plus their small transitive deps) are pinned to git tags rather than hex.pm, for environments where the hex.pm registry isn't reachable — see the comment in mix.exs.
