# Flow Extensions

Add custom property editors to individual input parameters. Provide picklist options for Apex action input parameters. Add custom headers to Apex actions.

- **[Choose a Transcription Model for Converting Audio to Text](https://help.salesforce.com/s/articleView?id=release-notes.rn_automate_flow_transcription_model_speech_to_text.htm&release=262.0.0&type=5)**  
    Get more control over how your audio is transcribed. The Transcription Model parameter provides two models, Whisper V3 Turbo and ElevenLabs Scribe V2, for the Convert speech to text and Convert Base64 speech to text actions to fit your transcription needs, such as audio quality, language, and data handling requirements. This parameter is available in Agentforce Builder, Flow, and REST.
- **[Add Custom Property Editors to Individual Apex Action Inputs](https://help.salesforce.com/s/articleView?id=release-notes.rn_automate_flow_extend_partial_cpes_for_apex_actions.htm&release=262.0.0&type=5)**  
    Developers can now build and assign custom property editors (CPE) to individual input parameters rather than entire Apex actions. A Lightning web component (LWC) can control a single input parameter or manage multiple related parameters. Input parameters without CPEs continue to use the standard property editor in Flow Builder. This approach gives developers fine-grained control over parameter configuration with less complexity.
- **[Define Picklist Values for Apex Action Inputs](https://help.salesforce.com/s/articleView?id=release-notes.rn_automate_flow_extend_define_picklist_values_for_apex_action_inputs.htm&release=262.0.0&type=5)**  
    Developers can provide picklist options for Apex action input parameters to simplify action configuration. Developers use the ProvidedValuesList standard additional attribute to specify comma-separated values or reference an Apex class that extends DynamicPicklist. Each input parameter supports up to 500 total picklist values. In Flow Builder, users select valid values from the input parameter’s picklist, which reduces configuration errors.
- **[Customize an Apex Action’s Standard Property Editor Header](https://help.salesforce.com/s/articleView?id=release-notes.rn_automate_flow_extend_add_custom_header_for_apex_action.htm&release=262.0.0&type=5)**  
    Developers can now add a custom header to their Apex action. The header guides users with context and instructions when they configure the action in Flow Builder. The header appears at the top of the property panel and provides context, instructions, or additional information to improve the configuration experience.
- **[Streamline Metadata Selection for Apex Action Inputs](https://help.salesforce.com/s/articleView?id=release-notes.rn_automate_flow_builder_assign_metadata_types_to_apex_input_parameters.htm&release=262.0.0&type=5)**  
    Developers can streamline metadata record selection for users who configure Apex actions in Flow Builder. When defining their Apex actions, developers assign setup entity types to input parameters. Then users can select from valid records in Flow Builder, avoiding errors when they configure the action.
- **[Expose Style Settings for Your Custom Flow Screen Components](https://help.salesforce.com/s/articleView?id=release-notes.rn_automate_flow_screens_styling_hooks.htm&release=262.0.0&type=5)**  
    Let flow authors customize Lightning web components (LWC) by adding styling hooks to your code. The hooks define which properties an author can adjust in Flow Builder, such as colors and dimensions to match branding needs.
