🌟 Investec Developer Community Projects

A community‑curated directory of open‑source tools, demos, and apps built with Investec APIs and Programmable Banking.

This repo is the “show‑and‑tell” corner of the community — come browse, borrow ideas, and ship something great.

Heads-up: projects listed here are created by the community and are not official Investec products. Always review code before running it and prefer Sandbox when testing.

GitHub License PRs Welcome


🧭 Start here (pick your quest)

🚀 I’ve built something — I want it featured

  1. Submit your project via the Build Submission Form
    👉 Submit a build
  2. After review, it will appear on the Community Showcase
    👉 View the showcase

No build is too small. The community learns fastest when people share their “rough diamonds” — not just polished gems.

🧪 I want to build something — where do I begin?

🧰 I want to improve this repo

  • Fix a broken link, improve a description, or add a new project entry: 👉 Open a pull request

🔒 Security & privacy (because: bank)

Please do not submit or link to projects that include:

  • API keys, secrets, tokens, private certs (even “temporary” ones)
  • personal/customer data (including screenshots with sensitive info)
  • instructions that encourage abuse of the platform

If your project needs credentials, use a .env.example and document setup for Sandbox safely.


✅ What makes a top‑class submission?

A project is easiest to review (and most likely to get attention) when it includes:

  • a one‑line tagline (“what is this?”)
  • clear setup/run steps in the project README
  • the tech stack + what Investec capability it uses (Accounts API / Card / both)
  • a screenshot/GIF (devs are visual creatures)
  • a license (so others know what they can do with it)

🗂️ Contents


🔎 Browse by use case

This list is use‑case first (because “I want to do X” beats “I want to use endpoint Y”).
Tip: use Cmd/Ctrl+F to jump to Python, React, Telegram, etc.

Legend: 🏆 = originally submitted as a challenge/bounty entry.

Demo Open Source Repo Description Tech Stack Author
Watch Consuming about GraphQL in the Browser As a follow up to his presentation GraphQL Wrapper for Investec open API, Marcin took us on a deep dive into the frontend developer experience. It was a really insightful session. If you want to learn more about the power of GraphQL and get some ideas of what you can do with the Investec Open API then you should check it out. Thanks Marcin!. ** Marcin
Watch or Read Transaction Event Listening Slide deck - Renen Watermeyer shows how he built a system that checks an account via the Investec OpenAPI to find new transactions every minute. He also demos how he created a webhook mechanism to push new notifications to another service. ** Renen
Watch or Read about Temporary Store of Value Slide deck - Lishen Ramsudh discusses the tool he’s been working on to streamline business operations and open up product possibilities through the use of a temporary store of value. The temporary store of value and automation of certain operations opens up a different trust relationship with a process being the custodian instead of hoping that a transaction is upheld. C# DotNet Core 3.1, Postgres, Redis, Xamarin Forms, (eventually include Docker, AWS ECS Fargate and API Gateway, AWS Aurora) Lishen
Watch or Read about Crypto Hedge Slide deck - Christo Bezuidenhout shares how he built a tool to hedge his spending against the Rand using crypto.

Why solve this? Figure out if I’m “over-cheesing”. Solution: My Friend “Bill” who reminds me to capture my receipts.. Telegram Bot API, Email, Wave @benblaine
WATCH: Investec @ Home Slide deck - A quick and dirty experiment to get my Investec account to interact with physical devices or a smart home. HomeBridge, Node.js, MQTT, HomeKit. @avgjoe
WATCH: Investec Open Banking CLI Slide deck - What it does: CLI for working with your bank account(s). No need to log into app or Web. Built to learn Deno. How it works: Very simple (one Typescript file). REPL (Read Eval Print Loop). Basic state held in-memory and shown in prompt (e.g. :closed_lock_with_key: vs :unlock:). Logged in (valid access token). Selected Account. Privacy mode. Auto-login if possible (looks in ENV variables for credentials).. Deno @adrianhopebailie
WATCH: Sync Investec to Sage One Slide deck - What it does: Syncing transactions automatically from Investec into Sage One. The current methods of importing transactions are manual or where you have to give your credentials to a third party. How it works: Retrieves the transactions from both Investec and Sage to compare. Removes transactions already synced. Sage will have the transaction hash. Compares manually added transactions in Sage One to stop duplication. Imports the transactions that are left over.. FastAPI, Sage API, Python, Heroku, Python Investec OpenAPI Wrapper @imraanp
WATCH: Flutterflys in Spring SparaBox and SparaBoxFlutter Slide deck - Personal budget app to explore the potentials of programmable banking.. Spring Boot, Keycloak, Flutter, Android @rendani10

WATCH: Toshigotchi Slide deck - What it is: Create an emotional connection to your spending habits. Money is a very emotionally charged topic and there we should be ways to make it more personable & relatable so we can react better to various financial circumstances. @jacousteau
WATCH: Paper Budget Slide deck: What it does: Sync transactions to YNAB budget and categorize them. Why create it? Keep budget up to date without manual intervention. Starlette, React and SQLite @ferdis
WATCH: Investec Query Bot What it does: It takes a user’s input, defines their intent, extracts queryable information, and generates a query to the DB. Eg. Show me all my transactions in Cape Town above 400 during June. Why create it? I was unsure of what to do with the card data, so figured why not let the user decide what they want to do with it. Swift UI (iOS), Ngrok, RASA NLP/U, SQLAlchemy, Python @lebo0
WATCH: Programmable Banking Rule (PBR) What it does: Allows the creation of rules that can be used at present for accepting/declining a transaction. Why create it? Most banking apps only allow hard limits to be set on spend. The idea with this is to put the account holder in charge of the rules of the card.. .Net Core, Blazor WebAssembly, Warewolf, Sql DB @HagashenNaidu
WATCH: InvestecCMD What it does: Sync transactions to Firestore as they come in. From Firestone, you can view you transactions in the iOS app as well as details of the transactions. You will also receive pushes when transactions are approved to the iOS App. Why create it? Great opportunity to learn how the Investec APIs works & to cut my teeth on a bunch of new techs I been dying to play with: firebase, cloud functions. typescript.. Native iOS, Swift, Firebase (Firestore, Cloud Functions) @WarrenFoxley
WATCH: Decentralised API What it does: The goal was to create a decentralised API to handle incoming beforeTransaction and afterTransaction requests before storing the data. This allows you to execute logic prior to storing the data and before validating transactions. Why create it? The main goal was to allow for validation logic on a transaction based on externally defined criteria, eg: limit daily spend, limit per transaction spend etc. Also, this provided an authenticated basecamp on which to build logic. Google Cloud Platform, Laravel @cwbmuller
WATCH: HankApp Hank is banking done right. Imagine a world where banking is an intuitive pleasure. It's our mission to make that world a reality. As banks open up their API's we aim to unlock their utility for the people. Flutter, Firebase @Chris.Fraser
WATCH: Investec Oracle What it does: Routes data through cloud functions to Google pub/sub, to which I can add multiple subscriptions for different applications. Why create it? To serve as a base for all transactions to flow through and to which different applications can connect to to receive transaction data. I also wanted to have the ability to replay transactions, which Google pub/sub provides and make it easy for other users to be able to spin up their own command center with a few clicks. Google Cloud Platform (Cloud functions, pub/sub, Firestore), Twillio, React, Zapper @bezchristo
WATCH: Purple Pigger Linked to the beforeTransaction function, PP checks all transactions (for now) and approves or declines them, to help you control budgets in certain periods. Keeping those wild nights, not too wild. I keep a mental count of my daily spending and how it affects my budget. Now I can get a machine to do it. Basically I'm lazy!. Firebase, Svelte @kamogelo.sebopelo
WATCH: Payments Splitter An app that let's you split the bill for a transaction with a friend using their email address. Node, AWS [@Yashu Tanna](yashutanna @yashutanna)
WATCH: Investec Logs investec-logs-functions AND investec-logs-web System to log transactions to Google Firebase using NodeJS and a frontend view with VueJS. Firebase @JeremyWalters
