Web SDK migration guides + Apple Pay

Two new guides to reach @tonder.io/web-sdk from wherever you are today:

• Migrating from the legacy SDK — from tonder-web-sdk v2 (InlineCheckout / LiteInlineCheckout), with the method-by-method mapping and the webhook change to the Short format — the part to budget for.
• Migrating from Direct API — move your checkout to the browser without changing your backend: same /process/, same webhooks, same reconciliation.

And Apple Pay gets its own payment-method page: the Web SDK button, domain registration, availability, and events.

Check your withdrawal balance by API

You can now check the available balance of your Mexican withdrawals account with the Get Balance API (GET /withdrawals/balance): see how much you can disperse before creating withdrawals via POST /process/. The Withdrawals guide includes the balance section with per-environment examples.

Nu México's SPEI code changes to 40638

By order of Banco de México, Nu México now operates as NUBANK, S.A., Institución de Banca Múltiple, and its SPEI code changed with it. This affects you if you send withdrawals to Nu accounts or receive transfers from them.

What to update:

• Payouts — send 40638 in institucionContraparte.
• Deposits — your system and your H2H connection must recognise 40638 in institucionOrdenante.

Code 90638 stopped working on 5 August 2026 at 18:00 Mexico City time. Anything sent with it is rejected.

• Banking reference — the institution code table.

New Analytics module in the Dashboard

We launched Analytics, a new Dashboard section that goes deeper into payment performance than the Home KPIs. It's organised into two views:

• Acceptance & Conversion — Overall, FTD and Trusted acceptance rate, APM conversion rate, acceptance rate over time, acceptance by method, card network performance, best and worst issuing banks, and the FTD vs. Trusted comparison.
• Deposit Analytics — total deposits, FTDs, active depositors and average deposit, plus deposit volume and count, the first-time deposit funnel and the deposit amount distribution.

Both views filter by period (Today, 7D, 30D, 90D or a custom range).

• Analytics — every KPI, chart and section explained.

New withdrawal statuses

Withdrawals now use the same status vocabulary as payments. If your integration expected the previous names, update it with this mapping:

New Web SDK (@tonder.io/web-sdk)

We launched the new Tonder Web SDK on npm: @tonder.io/web-sdk — a browser TypeScript SDK that replaces the Full/Lite variants for web with a single package:

• Secure card fields mounted in your own UI (createTonder → init → create('card_fields') → mount → pay).

• Saved cards and Card-on-File: enrollCard(), getCustomerCards(), removeCustomerCard() with a secure_token.

• Alternative methods: SPEI, OXXO Pay, and SafetyPay banks (getPaymentMethodBanks()).

• Hosted/3DS presentation via redirect or embedded (SDK modal).

• TypeScript types included, structured errors (AppError), and webhook-aligned responses. Also available via CDN (window.Tonder).

• Web SDK (guide) — quick start and payment flows.

• Web SDK Reference — every method, type, and error.

Tonder Web SDK plugin for AI agents

We launched tonder-ai-integrations: plugins that help AI agents integrate Tonder SDKs correctly. The first plugin is Tonder Web SDK (v0.1.7), for Claude Code, Claude Desktop, Codex CLI, and Codex Desktop. It packages a framework-aware integration skill (HTML, React, Next.js, Angular) and a local MCP server (tonder-docs) with versioned Web SDK documentation — recipes, API reference, errors, and payment statuses.

Supported flows: card payment, enrollment, saved cards, payment methods, and SafetyPay banks. It installs today from the GitHub repository marketplace.

• MCP Integration — what it is and how it works.
• Installation — step by step per host.
• Usage — example prompts and the MCP tools.

Documentation redesign

This documentation shipped a full redesign:

• Two-row header with centered search and tabs (Docs · API Reference · SDK Reference · Resources · Changelog).
• Sidebar with icon chips, breadcrumbs above every title, and a refreshed table of contents.
• Inset-style code blocks, minimal tables, and Tonder-branded share (OG) cards.
• Native diagrams (flows and sequences) in the Hosted Checkout guides.

New Tonder dashboard

We launched a redesigned dashboard — faster, clearer, and with native analytics: Home, Analytics, Fraud & Risk, Transactions, Withdrawals, Finances, Payment Links, Developers, Webhooks, and Team Members.

Also in this release

• Cash vouchers — the cash payment method formerly called SafetyPay is now Cash vouchers. The integration is unchanged (same API type). See Cash vouchers.
