The FinCalc API offers a comprehensive suite of endpoints to support users with their financial planning requirements. All endpoints comply with the JSON data format for both input and output. To update existing data, it is recommended to use the PUT method. Therefore, a GET request should first be made to retrieve the relevant information, and the necessary changes can then be made before using the PUT method to update the data. Please note that the GET request may include formatted values that are not relevant to the PUT request. However, these irrelevant values will be ignored during the PUT request process.
