🚨 Salesforce Automation at Risk: API Retirement Could Break Your Org in Summer ’25 — Act Now!

The Salesforce Summer ’25 release brings a silent disruptor that you cannot afford to ignore: if your system still uses API versions 21.0 through 30.0, your Salesforce automations, custom code, and third-party integrations may already be broken—or they soon will be. This isn't a future problem; for many, the impact has already begun.

Whether you manage your own org with an internal team or rely on external tools and custom solutions, these retired APIs power more than just old code. They underpin everything from daily sales reports to mission-critical customer service workflows. Once they fail, your essential business processes will grind to a halt, leading to lost productivity, inaccurate data, and potentially severe operational disruptions.

Now is the time to get ahead of this critical change. Proactive assessment and swift action are essential to avoid costly downtime. Micronetbd can help ensure your Salesforce environment stays secure, stable, and future-ready, preventing disruptions before they impact your bottom line.

🔍 Why the Salesforce API Retirement Matters (Even If You Don’t Code)

With the official retirement of API versions 21.0 through 30.0 in the Summer ’25 release, Salesforce has permanently ended support for these older versions across its Platform APIs. This isn't just about old code; it's about the very communication backbone of your Salesforce ecosystem. If you're still running anything built before 2020, there's a very high probability you're using one or more of these now-obsolete APIs.

This update has direct and severe impacts on critical areas of your Salesforce operations:

• REST & SOAP API Calls: Any external systems, middleware, or custom applications attempting to connect to Salesforce using these legacy API versions will immediately stop functioning. This means your lead syncs, order integrations, billing systems, and more could cease to transmit or receive vital data.
• Bulk API (v1) Jobs: Data loading and extraction processes using Bulk API v1 with versions 21.0-30.0 will fail. If you rely on these for daily data updates or large-scale migrations, prepare for immediate disruption.
• Login API: Custom applications or scripts that authenticate to Salesforce using the Login API with one of the retired versions will find their login attempts blocked.
• Metadata, Tooling, Connect & Tableau CRM APIs: Beyond standard data operations, these retirements impact your ability to deploy changes, manage metadata, use Chatter/Connect features in integrations, and refresh data in older Tableau CRM (formerly CRM Analytics) dashboards that haven't been updated. Critical backend systems could silently fail, leading to development roadblocks or inaccurate reporting.
• Apex Classes, Triggers & Visualforce Pages (Indirectly): While Apex code's own API version isn't directly retired, if your Apex logic makes outbound calls to other Salesforce APIs (REST, SOAP, Bulk, etc.) and specifies one of the retired versions in the endpoint URL or request headers, those specific calls will now return errors or behave unpredictably. This can break complex automations, integrations, and custom functionalities.

🚧 Who Is at Risk?

You don't need to be a seasoned Salesforce developer to feel the disruptive effects of this change. Many common scenarios put your org at risk:

• Custom Solutions Built Pre-2020: Any proprietary integrations, custom applications, or complex Apex code developed before 2020 that interacts with Salesforce APIs has a high likelihood of referencing these older, now-retired versions. Old code that hasn’t been re-versioned is likely to break or become unstable.
• Third-party Tools and Middleware: Popular integration platforms like Zapier, MuleSoft, Informatica, Boomi, or even older versions of the Salesforce Data Loader might be configured to use deprecated API versions. These essential tools may suddenly stop syncing if their connectors haven’t been proactively upgraded by the vendor or your configuration.
• AppExchange Packages: Some unmaintained or rarely updated AppExchange applications might still be tied to legacy APIs for their internal workings. While Salesforce manages the API versions of Apex classes within managed packages, the calls those packages make to external Salesforce APIs are still vulnerable.
• Internal Scripts and Reports: Even seemingly innocuous smaller Python or JavaScript scripts, reporting tools, or data analysis workflows that hit Salesforce endpoints could now be using invalid, retired API calls.

If any of these scenarios apply to your Salesforce org, your business could be running on unsupported technology, leaving you vulnerable to unexpected downtime.

✅ Your 5-Point Action Plan: What to Do Now

Here’s how you can stay ahead of the breakage, ensure business continuity, and future-proof your Salesforce environment:

1. Audit All API Usage and Code for Vulnerabilities:
   • Prioritize Event Monitoring: This is your most powerful tool to identify actual API calls using deprecated versions. In Salesforce Setup, navigate to Security > Event Monitoring > Event Log File Browser (or use tools that consume Event Log Files). Download and meticulously review "API Total Usage" event log files, "Bulk Data Load Jobs" details (for Bulk V1 jobs), and "Login History." This will pinpoint specific integrations, applications, or users affected.
   • Audit Apex Code & Metadata: While Apex class API versions aren't retired directly, search for any custom Apex classes, triggers, and Visualforce pages that make outbound calls to Salesforce APIs (REST, SOAP, Bulk, Metadata, Tooling, Connect) and explicitly define older API versions (21.0 through 30.0) in their endpoint URLs or HTTP headers. Tools like Salesforce Code Analyzer can help.
2. Upgrade API Versions in All Identified Components:
   • Update all custom code components, custom integrations, and data loader configurations that were identified in your audit as using deprecated API versions.
   • Crucially, we recommend jumping directly to API version 59.0 (or the latest available, likely 60.0 with Summer ’25) for all upgrades. This ensures you benefit from the newest features, enhanced security, and improved performance.
3. Review and Update External Integrations & Middleware:
   • Systematically check every connected app, external tool, connector, and direct API call, especially those embedded in middleware or ETL (Extract, Transform, Load) workflows.
   • Contact your third-party vendors immediately for compatibility updates if their connectors or applications are running on affected versions. Do not assume; verify.
   • Ensure all API calls are using your org's My Domain login URL, as this will become a mandatory requirement in upcoming releases.
4. Replace Deprecated Methods and Features:
   • Salesforce periodically retires specific outdated methods, fields, or functionalities within its APIs.
   • Review your codebase and Salesforce documentation to identify and swap out any legacy logic for modern, supported alternatives. This ensures long-term stability and compatibility.
5. Thoroughly Test Everything in a Sandbox (NON-NEGOTIABLE):
   • This is the most critical step. Before deploying any changes to your production org, conduct complete and comprehensive regression testing in a dedicated sandbox environment that has already received the Summer ’25 release.
   • Validate all triggers, flows, integrations, custom processes, and reporting. Consider enabling the "Retirement Enforcement" in the Release Updates section of your sandbox to fully simulate the production environment's behavior and catch any remaining issues.

🗓️ Suggested Timeline: Upgrade Before It’s Too Late
