Accept your first subscription payment

Example of how to create a recurring subscription using Copperx APIs
In this example, we will learn to start a subscription payment for 10 USDC/mo.
Before we start, few things to keep in mind
We are using our dev environment which supports on Polygon Mumbai Testnet and Goerli Testnet.
We will be using a curl to request Copperx APIs.
Make sure you generate your API_KEY from our Dashboard. If you don't have one, then generate it from here.
You will need test ERC20 Faucets to make the payment, you can request them from https://dashboard.copperx.dev/faucet. If you need more faucet, then feel free to contact our team via Telegram.
As you are using test environment, there is no real money involved. So feel free to play around.
To create a subscription, you first need to create a plan in Copperx Dashboard.
Let's create a plan to accept 10 USDC/mo.
1.Go to the Copperx Dashboard.
2.Login with your Copperx account.
3.Click Billing in the top menu and click on Plans.
4.Press Create Plan button on top-right to create a new plan.
5.Do fill plan title, description, recurring interval.
6.Do set price as 10 USDC.
7.Click Create Plan button and plan will be created.
Congratulations 🎉, you have successfully created your first plan on Copperx.
Now, let's move ahead and create a Checkout Session to create a subscription.
To create a Checkout Session, you will need priceId of the newly created plan. You will be able to find priceId of the plan from plan details page.
1.Open Plans dashboard​
2.Find the plan for which you want to create a Checkout Session.
3.Click ••• > Details to find more details.
4.On details page, you will find a field called Plan Id.
5.Press Copy icon to copy Price Id
Now let's go ahead and create subscription of our plan.
To create a checkout session, run below command in your terminal:
Make sure you update YOUR_API_KEY and PRICE_ID in the code.
curl --request POST \
--url 'https://api.copperx.io/api/v1/checkout/sessions' \
--header 'Authorization: Bearer {YOUR_API_KEY}' \
--header 'Content-Type: application/json'
--data-raw '{
    "successUrl": "https://copperx.io?cid={CHECKOUT_SESSION_ID}",
    "mode": "subscription",
    "lineItems": [{
        "priceId": "{PRICE_ID}" 
    }]
}'
