"Top 10 Salesforce Winter '26 Features for Developers"

🚨 Salesforce OAuth: Are your integrations silently breaking? If your integrations using the OAuth 2.0 Client Credentials Flow stopped working after the Winter ’26 release, you’re definitely not alone. “invalid_grant: no valid scopes defined” That’s the error countless admins and developers are seeing. The root cause? Salesforce now enforces valid scopes for the client credentials flow, scopes that may have been missing or unsupported in your Connected App. 📌 Read our latest post to understand exactly what changed and how to fix it: 👉 Salesforce OAuth “Invalid Scopes” Issue https://lnkd.in/erWApJgX Thanks Eric Praud for bringing it to our attention!

A small Salesforce change that could break your backend integrations in Winter ’26. If you’re using OAuth 2.0 Client Credentials Flow, Salesforce now returns a clear error when your Connected App has no valid scopes: invalid_grant: no valid scopes defined I’ve broken down: ✅ Why this happens ✅ What’s changing in Winter ’26 ✅ How to fix it in under 2 minutes Read the full post here 👉 https://lnkd.in/gwkwGrzn #Salesforce #Winter26 #OAuth2 #ClientCredentialsFlow #Integration #ConnectedApp #SalesforceDeveloper #CloudWithAbhi

New Salesforce release, new problems 😱: I'm seeing some mentions of it in the Trailblazer community, and it also happened to us. Connected apps with the client_credentials OAuth flow may break. You need to add to Selected OAuth Scope option: "Manage user data via APIs (api)", even if you granted full access... I personally can't find it in the release notes anywhere, did anyone hear about it?

Heads up about the Winter ’25 gotcha! Ran into an interesting one this week, our Client Credentials OAuth flow suddenly started failing with invalid_grant and no valid scopes defined. After some digging, we found out this was triggered by Salesforce’s Winter ’25 release. Turns out, Salesforce has tightened up its OAuth behavior: If your Connected App issues opaque tokens and doesn’t have a valid API-access scope, it’ll now fail the token request altogether. In our case, the app already had full and refresh_token scopes, but those don’t count for machine-to-machine (client credentials) flows. Adding the api scope fixed it immediately. 💡 Lesson learned: If you’re using Client Credentials for backend integrations, make sure your Connected App includes the "api" scope. Without it, your token requests will fail after Winter ’25. Reference: https://lnkd.in/ghS84-cq Props to the Salesforce team for enforcing better scope validation and a reminder for all of us to double-check those Connected App settings before production surprises hit. #Salesforce #OAuth #Winter25 #ConnectedApps #Security #SalesforceAdmins

Dreamforce summary. Salesforce Teams – Unstuck Unstuck (adjective) 1. Freed or loosened from being stuck • Example: “The deployment finally got unstuck after the Salesforce admin re-ran the failed Apex tests.” 2. No longer held back or hindered • Example: “Once the RevOps team aligned their Salesforce automations, the whole lead flow got unstuck.” 3. (informal, chiefly British) Falling into difficulty or failure • Example: “The integration project came unstuck when the new API version broke several connected apps.” Etymology: from un- (prefix meaning “not”) + stuck (past participle of stick).

Salesforce is deprecating Connected Apps — and that’s a big deal for anyone building integrations. Why? Because it kills the old “connect without installing anything” flow. No managed package. No install steps. Just API keys and go. That’s going away. From a UX standpoint, it feels like a step backward. From a security standpoint, it’s aligned with Salesforce’s bigger vision. At QOLOS, we’re not resisting the change — we’re building around it. We now support both connection methods: 🧩 Centralized Connected App — still works for quick sandbox testing and light usage (as long as Salesforce supports it) ⚙️ External Client Apps (ECA) — the new standard for secure, scalable integrations in production orgs Same product, new flexibility — with guides to make ECA setup easy, even if you’re not deep in OAuth flows. Salesforce is evolving. So are we. Not sure how this affects your setup?

Salesforce is deprecating Connected Apps. For anyone building integrations, that’s a pretty big shift — because it means we’re losing the ability to connect a third-party tool to Salesforce without installing anything (no managed package, no friction). From a user experience standpoint, it feels like a step back. But from a security standpoint, it’s part of Salesforce’s long-term vision. For Omnibloo, I’ve decided not to fight the change — but to adapt to it. Omnibloo now supports both connection methods: 🧩 Centralized Connected App: still available for quick sandbox connections and easy testing, while Salesforce keeps it active. ⚙️ External Client Apps (ECA): the new, secure standard — with a simple step-by-step guide to make setup straightforward for production orgs. This dual approach keeps Omnibloo flexible for admins and secure for production environments. Salesforce evolves — and Omnibloo evolves with it. If you’re unsure how to set up an ECA connection, I’ve added a link to book a short call. Happy to walk you through it and better understand your setup.

Salesforce developers just got a serious productivity boost by introducing Live Preview for Lightning Web Components (LWC). With Live Preview, you can now: - Instantly view updates as you code - Test and tweak components directly in your browser - Enjoy a smoother, faster, and more modern development workflow This is Salesforce’s take on “hot reload” — a feature that frontend developers have loved for years, now finally available in the Salesforce ecosystem. This could change the way we build and iterate on Lightning Components. What do you think — will this make your dev workflow faster?
