Start by reading Key Access Levels and then request your API keys.We recommend reading our Calven data models overview to become familiar with the core aspects of Calven's structure, in particular when interacting with our data warehouse APIs.
Calven uses conventional HTTP response codes to indicate the success or failure of an API request. In general: Codes in the 2xx range indicate success. Codes in the 4xx range indicate an error that failed given the information provided (e.g., a required parameter was omitted, a charge failed, etc.). Codes in the 5xx range indicate an error with Calven’s servers (these are rare).
