# Changelog

> Product updates and announcements for API Dental

<Update label="March 2026" description="v1.5.0">
  ## True Eligibility Now Free for All Users

  The **True Eligibility** transform is now included free with every standard Eligibility request — no add-on or trial plan required. All REST and GraphQL Eligibility responses now automatically include the `true_eligibility` field with 64 normalized data points (status, deductibles, maximums, coinsurance, coverage details, and more).

  ClearCoverage requests are not affected — True Eligibility applies to standard Eligibility only.

  ## Updated SDKs Released

  New SDK versions with full ClearCoverage support, typed response envelopes, error schemas (`UpstreamError`, `ApiError`), `dependent` field support, and `version` enum:

  * **C# / .NET v0.6.0** — [ApiDentalPro on NuGet](https://www.nuget.org/packages/ApiDentalPro)
  * **TypeScript v1.6.0** — [api-dental on npm](https://www.npmjs.com/package/api-dental)
  * **MCP Server** updated with all three endpoints (Eligibility, ClearCoverage, Payer List)

  ## Updated OpenAPI Specification

  The downloadable [OpenAPI spec](https://cdn.api.dental/openapi-defs/api-dental-openapi-spec-0.2.yaml) has been updated to v2.0.0 with:

  * All three endpoints (Eligibility, ClearCoverage, Payer List) with request examples
  * Response envelope schemas matching actual API structure
  * Error response schemas (400, 401, 402, 403, 429)
  * Authentication setup for Postman auto-configuration
  * DOB format documentation (MM/DD/YYYY)
</Update>

<Update label="March 2026" description="v1.4.0">
  ## Dashboard & Account Management Improvements

  Major updates to the customer dashboard experience:

  * **Multiple payment methods** — Add, remove, and set a default payment method from the Billing page. Non-default cards can be removed at any time.
  * **Billing history & invoices** — Transaction history now displays directly on the Billing page with status, amounts, and download links for Stripe invoices and receipts.
  * **Plan cancellation** — Self-service plan cancellation from Subscription & Plans. Cancels all subscriptions (plan + add-ons), disables API access, and sends a confirmation email.
  * **Improved navigation** — Dashboard and Account moved from header links to a streamlined avatar dropdown menu with quick access to all account sections.
</Update>

<Update label="March 2026" description="v1.3.0">
  ## Documentation & API Playground Overhaul

  Launched new Mintlify-powered developer documentation site at [docs.api.dental](https://docs.api.dental) with:

  * Full API reference with interactive playground for all endpoints
  * OpenAPI 3.1.0 specification with request/response schemas
  * Complete Tesia payer directory (775 payers) with per-payer capability details
  * SDK guides for TypeScript, C#, and MCP
  * Mermaid architecture and security flow diagrams
  * Inline error response documentation for all APIs
</Update>

<Update label="March 2026" description="v1.2.0">
  ## Eligibility & ClearCoverage Error Passthrough

  Upstream payer error details are now passed through to API responses for both Eligibility and ClearCoverage endpoints. Previously, errors from upstream payer services were wrapped in opaque internal error envelopes. Now responses include `statusCode`, `message`, and full `upstream` error body from the payer service — across both REST and GraphQL access paths.
