Function

Salesforce Functions (now retired) was a serverless computing service on the Salesforce platform that enabled developers to write custom code in languages such as JavaScript, TypeScript, or Java and execute it on Salesforce-managed elastic cloud infrastructure. Functions were designed for compute-intensive operations that exceeded Apex governor limits while maintaining secure access to Salesforce data through a dedicated SDK. The feature reached End of Sale on October 31, 2023, End of Renewal on January 31, 2024, and End of Life on January 31, 2025.

Salesforce Functions was a serverless computing service that let developers write custom code in languages like JavaScript, TypeScript, or Java and execute it on Salesforce-managed elastic cloud infrastructure. Functions were designed for compute-intensive operations that exceeded Apex governor limits while maintaining secure access to Salesforce data through a dedicated SDK. The service let developers write code in their preferred language and run it on demand from Apex, Flows, or external triggers.

Salesforce Functions reached End of Sale on October 31, 2023, End of Renewal on January 31, 2024, and End of Life on January 31, 2025. The product is no longer available and existing customers had to migrate off before the EOL date. Migration paths typically include using Apex with batch processing for compute work that fits within governor limits, building external services on hyperscaler platforms (AWS Lambda, Azure Functions, Google Cloud Functions) and integrating via REST APIs, or using Heroku for Salesforce-adjacent compute. Knowing Functions existed matters for context when reading older documentation or planning migrations from the retired service.
