Methods for Lightning Experience

Open CTI is in maintenance mode and is scheduled for retirement in February 2028. No new features or enhancements are being added to Open CTI. Effective immediately, Open CTI is deprecated and unavailable for newly created Agentforce Service orgs. To ensure long-term compatibility and access to the latest innovations, we recommend transitioning your development efforts to Salesforce Voice. For more information, see this Knowledge Article, learning map, and developer migration guide.

The way you implement Open CTI depends on your org’s user interface. There are separate Open CTI APIs for Salesforce Classic and Lightning Experience.You can’t swap the two Open CTI APIs in custom JavaScript code because they behave and function differently. Make sure that you think about where you want to implement your CTI system before you begin developing.
