The Contracts Public API provides a set of web services for users to create and modify data in the system. The current version uses REST and SOAP (deprecated) which allows the creation and modification of Companies, Contracts, Documents, Forms, Payments, Company Persons, Projects, and Users. Each of these entities has a service which provides create, update, and query methods. The Document service has an additional getDocumentContents method to obtain the file contents, and the Contract service has getAdditionalParties and setAdditionalParties methods to create and modify contract additional parties.
Keep in mind that the product was named Novatus until the summer of 2018, as a result many of the calls continue to reference the old name. The name of the product has been updated to reflect the new name of Conga Contracts, but the API calls retain the Novatus name.
