# Welcome to the Quickbase API Guide

> *Don't forget to check out our* [*JSON RESTful APIs*](https://developer.quickbase.com/)*, they can help you utilize and extend Quickbase with ease.*

The HTTP API is a collection of calls for accessing Quickbase applications over the web. It is an API over HTTP with XML payloads and an interface only; no components, modules, or libraries are installed at the app end.

In this guide:

- [Overview](/v1/docs/before-you-begin-user-setup) – Explains the basics about how the API works and how to set up and authenticate users using the API.
- [Quickbase API Call Reference](/v1/docs/quickbase-api-call-reference) – Describes each API call in detail (these are listed alphabetically.)
- [Appendix A: Error Codes](/v1/docs/error-codes) – Lists and describes the messages Quickbase returns when it encounters an error.
- [Appendix B: Managing Files](/v1/docs/upload-and-download-files) – Provides an overview of uploading and downloading file attachments
- [Appendix C: Building Queries](/v1/docs/building-and-using-queries) – Provides examples of how to use the different components that make up a query.
- [Appendix D: APIs and International Use of Quickbase](/v1/docs/appendix-d-apis-and-international-use-of-quickbase) – Provides information on API calls that are affected by changes to Quickbase's currency symbols, their placement relative to a number, number formats, and date formats.

Using the Quickbase HTTP API, you can:

- Provide secure access to Quickbase and Quickbase apps.
- Manage access through the Quickbase roles feature.
- Automate the app lifecycle: creation, deletion, and copying (cloning) of apps.
- Create, modify, and delete the app’s tables and fields
- Add, update, delete, and query table records
