# Development & APIs

Extend Marketing Cloud Next with developer tools for content and messaging. Use REST API to create, manage, and search CMS content across email, SMS, WhatsApp, and mobile app channels. Send emails to one or more recipients programmatically with the new Direct Email Send API.

- **[Create and Manage Content Programmatically Using Connect API](https://help.salesforce.com/s/articleView?id=release-notes.rn_mktg_development_apis_content.htm&release=264.0.0&type=5)**  
    Use Connect API to manage all types of content in your Marketing Cloud Next Content Management System (CMS). Create and modify SMS, WhatsApp, and mobile app messages. Manage your landing pages, forms, brands, images, videos, expressions, and tracked links. Create folder structures in your content workspace and view the items in specific folders.
- **[Send Emails with Direct Email Send API](https://help.salesforce.com/s/articleView?id=release-notes.rn_mktg_development_apis_direct_email_send.htm&release=264.0.0&type=5)**  
    Use Direct Email Send API to send emails to one or more recipients programmatically.
- **[Customize Content with Newly Supported AMPscript and Handlebars Functions](https://help.salesforce.com/s/articleView?id=release-notes.rn_mktg_development_apis_ampscript_handlebars_functions.htm&release=264.0.0&type=5)**  
    Do more with your marketing content with expanded support for AMPscript and Handlebars functions. Manage content in marketing objects by building rowsets, looking up rows, and claiming rows. Build more sophisticated personalization logic by using regular expressions. Create MD5 and SHA512 hashes to avoid sending sensitive content as plain text. Monitor the performance of specific areas in messages by creating impression regions.
- **[Load and Query Marketing Object Data at Scale with Bulk API](https://help.salesforce.com/s/articleView?id=release-notes.rn_mktg_marketing_object_bulk_api.htm&release=264.0.0&type=5)**  
    Run high-volume inserts, upserts, and queries on marketing object records using Bulk API. To manage marketing object schemas programmatically, use the Metadata API. If you use Salesforce APIs for other data operations, apply the same tooling to marketing data without adopting a separate integration path.
