Getting Started with Circle's Programmable Wallets -------------------------------------------------- Okay now, let's get practical! Here's a quick guide to creating a wallet in circle, I’ll be using python for the codes. ### Create a New User: * Head to Circle's developer portal: ([https://console.circle.com/wallets/overview](https://console.circle.com/wallets/overview)) and set up a developer account to start the process. * Next, you'll go to the API Keys Page and click on the "CREATE A KEY" button and proceed to type a name for your API Key. Select the "Standard Key" option for your API (this allows you all access to the API functions), Then click on the "CREATE KEY" button to create your API key, Copy the API key and save it properly. * to create a user open Vscode and create a new [user.py](http://user.py) file. * copy and paste these codes: `import requests url = "https://api.circle.com/v1/w3s/users" payload = {"userId":""} headers = { "Content-Type": "application/json", "Authorization": "Bearer " } response = requests.post(url, data=payload, headers=headers) print(response.text).` * Change "" to "User 1", and too your API key you got earlier from “Create a user”. then run it in the terminal with "python [user.py](http://user.py)". copy the output and save ### Acquire Session Token: We need to generate a secure session token. This is your key to authenticating your actions. * Create a new python file named “user\_token.py”. * copy and paste these codes: `import requests url = "https://api.circle.com/v1/w3s/users/token" payload = {"userId":""} headers = { "Content-Type": "application/json", "Authorization": "Bearer " } response = requests.post(url, data=payload, headers=headers ) print(response.text)` * change "" to "User 1", and too your API key you got earlier from Create a user. run it by typing python user\_session.py. copy the output and save (as we will be needing it to initialize the user). ### Initialize the User: Set up a new, unique Programmable Wallet for yourself. * Go to your Circle Developer’s Dashboard and get your [APP ID](https://console.circle.com/wallets/user/configurator) (it allows you to configure your User-Controlled Wallet integration). * or create a new python file and paste this code: `import requests url = "https://api.circle.com/v1/w3s/config/entity" headers = { "Content-Type": "application/json", "Authorization": "Bearer " } response = requests.get(url, headers=headers) print(response.text)` * this will return the App Id, copy and save [https://console.circle.com/wallets/user/configurator](https://console.circle.com/wallets/user/configurator) ### Initiate a Transfer: Use the Circle API to easily send USDC to another wallet on the network. * First Generate a tokenId for your wallet: Create a python file and name it wallet\_token.py. * Copy this code and paste it: `import requests url = "https://api.circle.com/v1/w3s/wallets/__WALLET_ID__/balances" headers = { "Content-Type": "application/json", "Authorization": "Bearer " } response = requests.get(url, headers=headers) print(response.text)` **N:B** We’re using testnet in this example, remember don’t send real USDC on testnet addresses as your funds might be permanently lost. ### View Wallet Balance: Check your new balance to confirm the transaction went through smoothly. --- *Originally published on [coderhema](https://paragraph.com/@coderhema/creating-programmable-wallets-solutions-with-usdc-and-circle)*
