CRM API (Application Programming Interface) is set of protocols enabling external applications to programmatically interact with CRM data and functionality. Works through HTTP requests (GET, POST, PUT, DELETE) to specific endpoints (/contacts, /accounts, etc.) authenticated via OAuth 2.0 or API keys. Returns JSON responses with requested data or operation results. Enables reading, writing, updating, and deleting CRM records from custom applications, websites, mobile apps, or integration tools without manual CRM interface access.

Custom Data Integrations are tailored solutions synchronizing information between systems with precise data mapping, transformation rules, validation logic, and synchronization schedules. Address challenges including incompatible data formats, complex business rules, real-time requirements, data quality enforcement, compliance-mandated handling, and legacy system connectivity.
