The post explains the tradeoffs: FIFO ordering requires waiting for successful delivery acknowledgement before sending the next message, which caps throughput (around 20 messages/sec in the best case due to network latency) unless configurable batching is used, and a failed delivery blocks the entire queue until resolved or the endpoint auto-disables. Regular endpoints remain best-effort, matching how Stripe, GitHub, and Shopify send webhooks, with independent per-message retries and full attempt-history visibility. FIFO endpoints can currently be enabled only through the dashboard's 'Advanced Endpoints' setting and application portal UI; a dedicated API is planned for release in the coming months. Both endpoint types can be used simultaneously per customer. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is the difference between Svix's FIFO endpoints and regular webhook endpoints? Regular Svix endpoints deliver webhooks independently on a best-effort basis, using multiple parallel workers, so throughput is limited only by consumer speed and failed messages are retried individually without blocking others. FIFO endpoints enforce strict ordering, waiting for a successful delivery acknowledgement before sending the next message, so a failure blocks the entire endpoint until resolved, and the endpoint auto-disables if all retries fail. _Teams weighing webhook ordering guarantees can track infrastructure changes like Svix's FIFO endpoints on daily.dev._ ### How much throughput can strict FIFO webhook delivery handle compared to best-effort delivery? Strict FIFO delivery can be limited to roughly 20 messages per second in the best case, because even fast deliveries take 40-50ms due to network latency and each message must be acknowledged before the next is sent. To work around this, FIFO endpoints support configurable batch sizes so multiple messages can be delivered together rather than strictly one at a time. _Developers tuning webhook throughput and ordering tradeoffs can follow updates like this on daily.dev._ ### How do I enable FIFO webhook endpoints in Svix? FIFO endpoints are enabled from the environment settings page on the Svix dashboard by turning on the 'Advanced Endpoints' setting; no code changes are required. Once enabled, customers can add a FIFO endpoint directly from the application portal and choose to send to a regular endpoint, a FIFO endpoint, or both. A dedicated FIFO endpoint API is not yet available and is planned for release in the coming months. _Anyone rolling out ordered webhook delivery can track API availability updates like this via daily.dev._ ## Similar posts on daily.dev - [The valley of webhooks](https://daily.dev/posts/the-valley-of-webhooks-6ekxclvor) · Hacker News · 0 upvotes · 0 comments - [Your Webhook Endpoint Is a Tiny Distributed System](https://daily.dev/posts/your-webhook-endpoint-is-a-tiny-distributed-system-izgpxyxum) · Ruby Flow · 0 upvotes · 0 comments - [Realtime AI Agent - A Deep Dive](https://daily.dev/posts/realtime-ai-agent---a-deep-dive-q4v3vciti) · System Design Newsletter · 0 upvotes · 0 comments - [Inside the Events Rail: How Atlassian Delivers 10 Billion Webhooks a Month](https://daily.dev/posts/inside-the-events-rail-how-atlassian-delivers-10-billion-webhooks-a-month-28sbia0pb) · Atlassian · 0 upvotes · 0 comments --- Tags: [#architecture](https://daily.dev/tags/architecture), [#distributed-systems](https://daily.dev/tags/distributed-systems) [View this post on daily.dev](https://daily.dev/posts/fifo-ordered-webhooks-delivery-y3lc62o7p) ```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":"FIFO Ordered Webhooks Delivery","url":"https://daily.dev/posts/fifo-ordered-webhooks-delivery-y3lc62o7p","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/fifo-ordered-webhooks-delivery-y3lc62o7p"},"datePublished":"2026-08-23T07:20:31.014Z","dateModified":"2026-08-23T07:23:36.734Z","description":"Svix has launched FIFO endpoints, giving webhook consumers the option to receive events in strict first-in-first-out order, alongside its existing best-effort...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/2445b012a1172276d256d8f85169d317?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/2445b012a1172276d256d8f85169d317?_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/fifo-ordered-webhooks-delivery-y3lc62o7p","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"architecture,distributed-systems","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":"FIFO Ordered Webhooks Delivery"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/fifo-ordered-webhooks-delivery-y3lc62o7p#faq","mainEntity":[{"@type":"Question","name":"What is the difference between Svix's FIFO endpoints and regular webhook endpoints?","acceptedAnswer":{"@type":"Answer","text":"Regular Svix endpoints deliver webhooks independently on a best-effort basis, using multiple parallel workers, so throughput is limited only by consumer speed and failed messages are retried individually without blocking others.
