OpenPhone API

The OpenPhone API enhances communication by integrating calls, texts, and contacts into a single, intuitive app that operates seamlessly across all devices. This API allows businesses to automate text messages, synchronize contacts, log activities in their CRM, and integrate OpenPhone deeply with their existing tech stack.

Key functionalities include automating messaging based on custom criteria, ensuring contact information is always up-to-date by syncing with your CRM, and recording all activities such as messages, call logs, transcripts, and summaries directly into your CRM. The API supports REST architecture with data returned in JSON format, secured by API key authentication.

Businesses can create custom workflows and integrations, making it easier to manage communications without switching between multiple platforms. The API also supports programmatic SMS messaging, though MMS is not currently available.

Rated highly in customer satisfaction, OpenPhone is trusted by over 50,000 businesses, from startups to large institutions, for its ease of use and comprehensive communication management capabilities.
