# FinCalc API Documentation ## Description This is version `2.0.0` of this API documentation. Last update on Nov 6, 2025. 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. ## Servers - https://api.fincalc.co.uk: https://api.fincalc.co.uk () ## Authentication The API accepts 2 different authentication methods: - O auth2 (oauth2) - Bearer auth (http) ## Endpoints - [Clients](https://apidocs.fincalc.co.uk/group/endpoint-clients.md) - [Company Client Tags](https://apidocs.fincalc.co.uk/group/endpoint-company-client-tags.md) - [Fact Find](https://apidocs.fincalc.co.uk/group/endpoint-fact-find.md) - [Household](https://apidocs.fincalc.co.uk/group/endpoint-household.md) - [Household Assets](https://apidocs.fincalc.co.uk/group/endpoint-household-assets.md) - [Household Assets Improvements](https://apidocs.fincalc.co.uk/group/endpoint-household-assets-improvements.md) - [Household Expenditure](https://apidocs.fincalc.co.uk/group/endpoint-household-expenditure.md) - [Household Incomes](https://apidocs.fincalc.co.uk/group/endpoint-household-incomes.md) - [Household Liabilities](https://apidocs.fincalc.co.uk/group/endpoint-household-liabilities.md) - [Household Liabilities Repayments](https://apidocs.fincalc.co.uk/group/endpoint-household-liabilities-repayments.md) - [Household Pensions](https://apidocs.fincalc.co.uk/group/endpoint-household-pensions.md) - [Household Pension Contributions](https://apidocs.fincalc.co.uk/group/endpoint-household-pension-contributions.md) - [Household Pension Withdrawals](https://apidocs.fincalc.co.uk/group/endpoint-household-pension-withdrawals.md) - [Household Savings](https://apidocs.fincalc.co.uk/group/endpoint-household-savings.md) - [Household Savings Contributions](https://apidocs.fincalc.co.uk/group/endpoint-household-savings-contributions.md) - [Household Savings Withdrawals](https://apidocs.fincalc.co.uk/group/endpoint-household-savings-withdrawals.md) - [Household Timeline & Goals](https://apidocs.fincalc.co.uk/group/endpoint-household-timeline-goals.md) - [Relationships](https://apidocs.fincalc.co.uk/group/endpoint-relationships.md) - [Status](https://apidocs.fincalc.co.uk/group/endpoint-status.md) - [User](https://apidocs.fincalc.co.uk/group/endpoint-user.md) [Powered by Bump.sh](https://bump.sh)
