The Launch Center provides a list of steps to help make sure your app is Plaid-optimized and production ready.

Developer tools include our SDKs, Postman collection, and OpenAPI file.

For information about official and community supported libraries for both the Plaid API and the Link frontend component, see libraries.

The Postman Collection provides an easy, no-code way to explore the API.

The Plaid OpenAPI file is available on GitHub. This file describes the Plaid API in a standardized way suitable for usage with tools for testing, client library generation, and other purposes that ingest OpenAPI/Swagger definition files.

Plaid maintains a repo of configuration objects suitable for usage as custom Sandbox users to help you test apps in Sandbox.

For testing Enrich, Plaid provides a list of Sandbox-compatible Enrich transactions.

For the Assets and Income products, Plaid maintains a Credit attributes library of helper scripts that can be used to derive various useful attributes from an Asset Report or Bank Income.

Plaid's AI toolkit includes a number of tools to help you incorporate AI tooling into your development flow.

Our vibe coding tips article contains recommendations on how to get your favorite AI coding assistant or IDE to work best with Plaid, including common mistakes AI tools will make and how to fix them.

Plaid's Dashboard MCP server allows you to access Plaid's diagnostics and analytics tools to retrieve information about Link analytics, Item health, and more, using your favorite LLM-powered application or client library.

In accordance with the llms-txt proposal, an index of all of Plaid's documentation can be found in LLM-friendly Markdown at https://plaid.com/llms.txt. You can find a Markdown equivalent of nearly all Plaid documentation pages by adding index.html.md to the end of the URL. For example, a Markdown version of https://plaid.com/docs/auth can be found at https://plaid.com/docs/auth/index.html.md.

Consult the documentation for your favorite LLM-powered coding assistant for the best way to incorporate this documentation into your workflow, as best practices are changing frequently. Often, adding a prompt like the following in your helper file can be useful.

3For instructions on how to use the Plaid API, please go to 
4https://plaid.com/docs/llms.txt. There you can find a list of other
5documentation pages that you can retrieve to obtain the necessary 
6information. If you need to search for additional documentation, you
7should first try to use a link that is listed in the llms.txt file.

A single file containing all of Plaid's documentation can be found at https://plaid.com/docs/llms-full.txt, although it is generally too large to fit into most models' context windows.

Trying to prompt your favorite LLM-powered coding tool to build a Plaid-powered application? Plaid provides several detailed guides you can reference within your LLM coding session that will provide your agent with additional context. You can use these guides to more quickly build proof of concept applications, or to kick-start your development process.

Plaid also provides a Sandbox MCP server, which, when run locally, provides helpful utilities for building and testing your Plaid-powered applications. You can use the Sandbox MCP server to generate realistic looking custom user data, simulate webhooks, or create public tokens in the Sandbox environment.

Bill is our helpful robot platypus that reads our docs for fun! You can ask Bill any time you need help with the Plaid API. Remember that Bill (like all of us) isn't perfect, even though he tries his best -- he can sometimes make mistakes, and he can only provide answers based on Plaid's published documentation and other publicly available information sources.

You can join the Plaid Developer Community on Discord or ask questions on Stack Overflow.
