The post walks through setting the Accept header to text/event-stream, handling HTTP 307 redirects, including the auth parameter for protected data, and parsing put/patch/keep-alive/cancel/auth_revoked events. It also links to Ruby and Python command-line chat client examples demonstrating the feature. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I stream realtime updates from the Firebase REST API without a client library? Set the Accept header to text/event-stream when making a request to the Firebase REST API, and the server will push updates using the EventSource/Server-Sent Events protocol. The client must also follow HTTP 307 redirects, since Firebase directs the connection to the correct machine via the Location header. _daily.dev surfaces implementation details like this for developers building realtime features without a full SDK._ ### What event types does the Firebase REST API streaming endpoint send? The server sends five event types: put, patch, keep-alive, cancel, and auth_revoked. A put event replaces the cache at a given path with new data, while a patch event updates or adds specific keys under a path rather than replacing the whole subtree. _Developers wiring up Firebase streaming clients can track protocol specifics like this via daily.dev._ ### How do I authenticate a request when streaming from a protected Firebase location? Include an auth parameter in the request, using either your Firebase Secret or an authentication token, for example appending auth=CREDENTIAL as a query parameter in a curl request. This is required for any Firebase location whose read access is restricted by Security and Firebase Rules. _daily.dev helps developers keep up with API authentication patterns across backend services like Firebase._ ## Similar posts on daily.dev - [Server-Sent Events: streaming from server to browser](https://daily.dev/posts/server-sent-events-streaming-from-server-to-browser-knzthsbgt) · Flavio Copes · 1 upvotes · 1 comments - [Server-Sent Events vs WebSockets: 2026 Developer Guide](https://daily.dev/posts/server-sent-events-vs-websockets-2026-developer-guide-2lwprquzl) · Alex CloudStar · 0 upvotes · 0 comments - [Server Sent Events](https://daily.dev/posts/server-sent-events-83njlflzt) · RUBYLAND · 2 upvotes · 0 comments - [Server-Sent Events in ASP.NET Core and .NET 10](https://daily.dev/posts/server-sent-events-in-asp-net-core-and-net-10-rqln4wisb) · Milan Jovanović · 25 upvotes · 0 comments - [How to Make Your AI App Faster and More Interactive with Response Streaming](https://daily.dev/posts/how-to-make-your-ai-app-faster-and-more-interactive-with-response-streaming-tl5k42oon) · Towards Data Science · 1 upvotes · 0 comments --- Tags: [#python](https://daily.dev/tags/python), [#rest-api](https://daily.dev/tags/rest-api), [#firebase](https://daily.dev/tags/firebase), [#server-sent-events](https://daily.dev/tags/server-sent-events) [View this post on daily.dev](https://daily.dev/posts/announcing-streaming-for-the-firebase-rest-api-h0dmvgpkc) ```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":"Announcing Streaming for the Firebase REST API","url":"https://daily.dev/posts/announcing-streaming-for-the-firebase-rest-api-h0dmvgpkc","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/announcing-streaming-for-the-firebase-rest-api-h0dmvgpkc"},"datePublished":"2026-08-23T12:20:23.146Z","dateModified":"2026-08-23T12:30:42.595Z","description":"Firebase's REST API now supports streaming via the EventSource/Server-Sent Events protocol, enabling realtime notifications on platforms not covered by...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/7ed721de96163685d26ab7e314be3ebc?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/7ed721de96163685d26ab7e314be3ebc?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Firebase","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":"Firebase","logo":"https://media.daily.dev/image/upload/s--i395oqZH--/f_auto,q_auto/v1787487448/logos/firebase-blog?_a=BAMAMicg0","url":"https://daily.dev/sources/firebase-blog"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/announcing-streaming-for-the-firebase-rest-api-h0dmvgpkc","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"python,rest-api,firebase,server-sent-events","timeRequired":"PT3M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Firebase","item":"https://daily.dev/sources/firebase-blog"},{"@type":"ListItem","position":3,"name":"Announcing Streaming for the Firebase REST API"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/announcing-streaming-for-the-firebase-rest-api-h0dmvgpkc#faq","mainEntity":[{"@type":"Question","name":"How do I stream realtime updates from the Firebase REST API without a client library?","acceptedAnswer":{"@type":"Answer","text":"Set the Accept header to text/event-stream when making a request to the Firebase REST API, and the server will push updates using the EventSource/Server-Sent Events protocol.
