How to Push Leads and Contacts into CRMs with Unified's CRM API

Unified's CRM API provides a streamlined approach to pushing leads and contacts into various CRMs by offering a consistent write interface that accommodates the variability across different CRM systems. The API allows users to create, update, retrieve, and list CRM objects—such as contacts, leads, and companies—using a set of normalized schemas, thereby reducing the need for hardcoded logic specific to each CRM. The guide focuses on implementing safe and portable write flows using TypeScript, including creating contacts and leads, associating records through IDs or names, and writing custom fields via metadata. It emphasizes the importance of understanding integration-specific requirements and recommends using find-then-update patterns to avoid data duplication, as well as verifying successful writes through retrieve endpoints. The guide also highlights the necessity of handling CRM-specific variations in required fields, association behaviors, and custom field support, advising users to refer to the Feature Support tab for specific integration details.
