Plus AutoConfig for polling endpoints, the Dashboard MCP for Ingest, and IAM roles for AWS destinations. Svix October update: Destinations API, MCP Events for ChatGPT, custom domains Svix ---------------------- MCP Events for ChatGPT ---------------------- ChatGPT now supports MCP Events, so it can subscribe to things happening in your product, like a new comment or a merged pull request, and act on them right in the user's chat. Your MCP server delivers those events as Standard Webhooks, and two new Svix routes handle the subscriptions for you: callback verification, refreshes and expiry, secret rotation, and retries. Read how it works in How ChatGPT MCP Events Work (It's Webhooks) ( https://www.svix.com/blog/mcp-events/ ). -------------------------------------------- Advanced Destinations, now with a public API -------------------------------------------- Advanced endpoint types are now called Advanced Destinations ( https://docs.svix.com/advanced-destinations ), and they have a public /destination API. Create, update, and delete polling endpoints, S3 buckets, SQS queues, Postgres tables, and the rest for your customers in code, the same way you already manage regular endpoints. It's in all the SDKs and the CLI as of v2.4.0 (v2.6.0 for PHP). -------------------------------- AutoConfig for polling endpoints -------------------------------- Webhooks AutoConfig ( https://www.svix.com/blog/webhooks-autoconfig/ ) now works with polling endpoints, so your customers can declare their polling endpoint in code next to the worker that reads from it. There's also a new public AutoConfig API for creating, rotating, and revoking AutoConfig tokens from your own code. Read how it works in Bringing AutoConfig to Polling Endpoints ( https://www.svix.com/blog/autoconfig-polling-endpoints/ ). ------------------------------------------------ Custom domains for everything your customers see ------------------------------------------------ The App Portal, Event Catalog, Ingest, polling endpoints, and the MCP server can now all live on your own domain, like webhooks.example.com, managed from one page in the dashboard. Available on Professional and Enterprise. See the custom domains docs ( https://docs.svix.com/custom-domains ). ------------------------------------ Manage Ingest from your coding agent ------------------------------------ The Svix Dashboard MCP ( https://www.svix.com/dashboard-mcp/ ) lets your coding agent set up Ingest sources, read the payloads you've received, debug failed deliveries, manage signing secrets, and resend messages. Connect from your organization settings with ready-made snippets for Claude Code, Codex, Cursor, VS Code, and more, now with OAuth sign-in. ---------------------------------------------- New Free plan, Basic, and a Professional trial ---------------------------------------------- There’s a new Free plan, capped at 50k messages a month with no credit card required. We also have a new Basic plan that starts at $20 a month, with the 99.9% uptime SLA, pay-as-you-go pricing, and white-label headers, which used to require Professional. Professional comes with a 30-day free trial. Details are on the pricing page ( https://www.svix.com/pricing/ ). ------------------------------ IAM roles for AWS destinations ------------------------------ S3, SQS, SNS, EventBridge, and Redshift destinations can now authenticate by assuming an IAM role with an external ID instead of using static access keys, so there are no long-lived credentials to hand over or rotate. See the docs ( https://docs.svix.com/stream/sinks/s3#authenticating-with-amazon-iam-roles-and-sts ). --------------------- Read more on the blog --------------------- There's more in this month's changelog, including a new Elasticsearch and OpenSearch destination, tracing connectors for Datadog, New Relic, and Grafana Cloud, retry times in the App Portal, a new attempt stats API, transformation testing for more sink types, and Stream and Destination support in the PHP SDK: https://www.svix.com/blog/changelog-10-2026/ ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ Twitter ( https://x.com/SvixHQ ) LinkedIn ( https://www.linkedin.com/company/svix/ ) Unsubscribe ( https://track.customer.io/unsubscribe/dgTF3gcDAIvtAYrtAQGhak9jRvEHFulhFV00SJU= )
