Salesforce Summer ’27 Update: Retirement of SOAP API login() Authentication

Overview

Salesforce has announced the retirement of the SOAP API login() authentication method by Summer ’27. This method allows integrations to authenticate using Username + Password + Security Token.

AutoRABIT currently provides a legacy authentication option that uses this mechanism to connect to Salesforce organizations. Since Salesforce is deprecating this method, it may impact integrations that rely on this authentication approach.

Impact

If your AutoRABIT connection to Salesforce uses the following authentication method:

• Username

• Password

• Security Token

then it relies on the SOAP API login() method.

Once Salesforce retires this functionality, this authentication method will no longer be supported by Salesforce, and integrations using it may fail to authenticate.

Where to Find the Setting

You can locate this setting in Salesforce Setup.

Navigation: Setup → Quick Find → User Interface → Enable SOAP API login()

If this option is enabled, external systems can authenticate using the SOAP API login() call.

Important Note

Salesforce has announced that SOAP API login() will be retired in Summer ’27. For new Salesforce orgs, this option is disabled by default.

Even if you see a message about the retirement when hovering over the setting, it simply indicates the future deprecation notice and does not affect the current configuration.

Recommendation

Salesforce is moving toward a modern integration model using External Client Apps.

External Client Apps are designed for secure API-based integrations and provide stronger authentication and governance controls for external systems.

AutoRABIT recommends using authentication based on OAuth authentication via External Client Apps.

This approach aligns with Salesforce’s long-term security and integration strategy.
