Also released: public FIFO Endpoints for strictly ordered webhook delivery, a new Cron source type for Svix Ingest, an improved Ingest source type selector UI, a UI for configuring OAuth 2.0 and mTLS webhook authentication on Enterprise tier, and the ability to set custom endpoint headers at endpoint creation time via the API. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What breaking changes did the Svix SDK overhaul introduce in February 2025? Svix overhauled all of its SDKs, moving from 90% auto-generated code to 100% automatically generated API code using a custom-built SDK generator, replacing the previous third-party generator. This fixed issues with certain API endpoints like patch endpoints, but introduced minor breaking changes such as renamed option structures and added parameters, all catchable statically at compile time, type checking, or import. _Teams upgrading webhook SDKs can track breaking changes like these via daily.dev._ ### How do FIFO Endpoints differ from regular webhook delivery in Svix? FIFO Endpoints deliver webhooks in strict first-in-first-out order, unlike regular Svix webhooks which are delivered independently with ordering only on a best-effort basis. FIFO Endpoints reuse the same underlying infrastructure originally built for Polling Endpoints, and Svix plans to build more features on top of that infrastructure. _Developers choosing an ordered webhook delivery approach can follow updates like this on daily.dev._ ### Can Svix Ingest trigger webhooks on a schedule instead of an external event? Yes, Svix Ingest added Cron as a source type, letting webhooks fire based on a defined Cron schedule rather than only reacting to external events. To set it up, create a Cron Ingest Source from the Sources view, choose Cron, and configure the schedule, payload, and payload content type, then attach webhook endpoints as with any other Ingest Source. _Engineers building scheduled workflows can keep tabs on ingest tooling changes via daily.dev._ ## Similar posts on daily.dev - [Svix Changelog September 2026](https://daily.dev/posts/svix-changelog-september-2026-zrvha2knm) · Svix Blog · 1 upvotes · 0 comments - [Svix SDKs and CLI v2 released](https://daily.dev/posts/svix-sdks-and-cli-v2-released-vmkfe9obm) · Svix Blog · 5 upvotes · 0 comments --- Tags: [#architecture](https://daily.dev/tags/architecture) [View this post on daily.dev](https://daily.dev/posts/svix-changelog-february-2025-rocrralk7) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Svix Changelog February 2025","url":"https://daily.dev/posts/svix-changelog-february-2025-rocrralk7","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/svix-changelog-february-2025-rocrralk7"},"datePublished":"2026-08-23T07:20:32.469Z","dateModified":"2026-08-23T07:24:20.674Z","description":"Svix's February changelog covers an overhaul of all Svix SDKs, moving from a mostly auto-generated setup to a fully automated, custom-built generator, which...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/82cafcd22288c1ae30192c6e9bb00f49?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/82cafcd22288c1ae30192c6e9bb00f49?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Svix Blog","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Svix Blog","logo":"https://media.daily.dev/image/upload/s--Shf9MlOr--/f_auto,q_auto/v1787469609/logos/svix?_a=BAMAMicg0","url":"https://daily.dev/sources/svix"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/svix-changelog-february-2025-rocrralk7","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"architecture","timeRequired":"PT5M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Svix Blog","item":"https://daily.dev/sources/svix"},{"@type":"ListItem","position":3,"name":"Svix Changelog February 2025"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/svix-changelog-february-2025-rocrralk7#faq","mainEntity":[{"@type":"Question","name":"What breaking changes did the Svix SDK overhaul introduce in February 2025?","acceptedAnswer":{"@type":"Answer","text":"Svix overhauled all of its SDKs, moving from 90% auto-generated code to 100% automatically generated API code using a custom-built SDK generator, replacing the previous third-party generator.
