Changelog

What shipped, newest first. Changes to the API's contract also change the OpenAPI document's info.version.

2026-10-25: Developer tools for switching

• A Postman collection of every endpoint, built from the OpenAPI document, to import by link.
• The API mapping guide for code moving from Stripe: objects, calls and webhook events side by side, and what has no equivalent yet.
• The Anytime CLI preview, documented ahead of its npm release: forward test events to localhost and trigger test events.
• A Developer tools card in Settings → Developers linking all of these.

2026-10-24: API reference, guides and AI agents hub

• A reference page per API resource, built from the OpenAPI document: every endpoint with its parameters, permission, Idempotency-Key support, errors, and samples in curl, Node.js, the Node SDK and Python. Start at Payments.
• Guides you can copy and run: Next.js checkout, webhook verification in Node.js, Python and PHP, safe refunds, nightly payout reconciliation, subscriptions, usage billing and stablecoins.
• The AI agents hub: connecting the MCP server in each client, least-privilege keys for agents, custom agents and a prompt library.
• An error code catalogue, a glossary and the OpenAPI page.
• OpenAPI document 2026-10-24: usage events are marked idempotent by their own idempotencyKey rather than the header, writes that take an Idempotency-Key list their 400, and the usage object's daily points are { date, quantity }.

2026-10-24: Restricted keys and a much larger API

• Restricted API keys: none, read or write per resource, with Full access and Read only presets. A request the key can't make answers 403 PERMISSION_DENIED naming the permission.
• New endpoints, 53 in all: refunds (within your approval limit), customers create and update, products, subscription plans and subscriptions with cancel, pause and resume, discount codes, payouts and balance and disputes (read only), and webhook endpoints.
• The API described in OpenAPI 3.1, with each operation's permission.
• A Node SDK preview with typed resources, auto-pagination, safe retries and webhook verification. It isn't on npm yet.
• The MCP server grew to 48 tools covering every resource above but usage events, each naming the permission it needs.
• 25 webhook event types, covering payments, refunds, disputes, invoices, subscriptions, customers, payouts and payments held for review.

2026-10-24: Checkout, risk and billing

• One-click checkout: customers who opt in pay with a saved card after a code by email. See Fraud rules & 3D Secure.
• Checkout risk rules and a manual review queue for held card payments. See manual review.
• Stablecoin checkout: customers pay links and invoices in USDC or USDT straight to your business wallet.
• Subscription discount codes and plan changes with proration, and usage-based billing with meters and the usage events API.

2026-10-24: Money movement and integrations

• QuickBooks Online and Xero sync: payments, card processing, refunds and payouts posted through a clearing account.
• Bank transfer instructions on invoices, your payout schedule in Settings → Payouts, and Form 1099-K requests from Reports → Year-end.
• WooCommerce plugin. The Shopify app is waiting for Shopify's approval, and the Zapier app isn't in Zapier's directory yet: both pages show how they'll work.
• Switch from Stripe: an importer for customers, products, plans, discount codes, links and open invoices, and invitations that move subscribers without charging twice.

2026-10-23: Anytime Capital Payments launches

• Payment links, invoices, a Pay button and inline checkout for your website, and in-person QR payments.
• The REST API: payment links, invoices, payments and customers, with idempotency, pagination and signed webhooks.
• The MCP server for AI assistants, and these docs as Markdown with llms-full.txt.
