Freshdesk, an AI-driven ticketing platform by Freshworks, enhances customer support experiences when integrated with other applications, necessitating the retrieval of a unique API key. Users can start a free trial or log in to access their API key, which is crucial for integration. Freshdesk offers four pricing plans—Free, Growth, Pro, and Enterprise—each with varying features, including editing tickets and creating them from emails and social posts, with advanced plans providing additional functionalities like audit logs. The number of API calls permitted depends on the plan, and common errors include client validation, authentication failures, and rate limit exceedances. Merge's Unified API offers a solution for integrating various ticketing tools, such as Asana, Trello, or GitHub, streamlining integration management.
