# Chargebee new subscription notifications on your phone

> Get a push notification when a customer starts a Chargebee subscription, with the plan, price and any trial.

- Company: Chargebee (https://www.justpush.io/recipes/chargebee)
- Event: `subscription_created` (subscription_created)
- Tags: Payments & billing, Subscriptions
- Install: https://studio.justpush.io/recipes/chargebee/subscription-created
- Web page: https://www.justpush.io/recipes/chargebee/subscription-created

## Setup

1. Click Install in Studio and sign in. The recipe is added to your account and you get a personal webhook URL.
2. In Chargebee, go to Settings > Configure Chargebee > API Keys and Webhooks, open the Webhooks tab and click Add Webhook.
3. Paste your webhook URL (shown in Studio after install) as the Webhook URL (add ?site=your-site for dashboard buttons).
4. Under Events to Send, pick only subscription_created and save the webhook.
5. Under **Events to Send**, pick only `subscription_created` (Chargebee selects All Events by default). Subscriptions created with a backdated start send `subscription_created_with_backdating` instead, which this recipe ignores.
6. **Dashboard button:** Chargebee events don't include your site's name, so add it to the webhook URL to get a button that opens the subscription in Chargebee. Use the part before `.chargebee.com` in your dashboard address (test sites usually end in `-test`):
7. ```
8. your webhook URL (shown in Studio after install)?site=your-site
9. ```
10. Without `?site=` the push arrives without a button.
11. Built for API version **v2** events. Chargebee's **Test Webhook** button sends a sample of the event you pick, which should give a normal push.
12. Chargebee doesn't sign webhooks. It can send a username and password (basic authentication), but JustPush doesn't check them yet, so you can leave that off. Keep your endpoint URL private.

## Code

Studio calls `handleRequest(request)` with the incoming webhook (`{ method, headers, body, query, raw }`) and sends the message object it returns. Returning `null` sends nothing.

```js
// Chargebee → subscription_created
// Fires when a new subscription is created, including ones that start in trial or at a future date.
// Docs: https://apidocs.chargebee.com/docs/api/events/webhook/subscription_created
//
// Paste this into a JustPush Studio integration and add a Chargebee webhook for the
// "subscription_created" event pointing at the integration's endpoint URL.
// Add ?site=your-site to the URL to get a button that opens the subscription in Chargebee.

// Chargebee amounts are whole numbers in the currency's smallest unit (2900 = €29.00),
// except for zero-decimal currencies such as JPY, where 500 means ¥500. This is Chargebee's
// own list: https://www.chargebee.com/docs/billing/2.0/site-configuration/supported-currencies
const ZERO_DECIMAL = new Set(["clp", "isk", "jpy", "krw", "mga", "pyg", "vnd", "xaf", "xof", "xpf"])

## FAQ

No. Install the recipe in Studio, paste your webhook URL into Chargebee and you are done. The code is there if you want to change the text, the sound or the buttons.

### Can I change what the notification says?

Yes. After install the recipe's code is yours. Edit it in Studio and test it against the sample payload before you save.

### What does it cost?

JustPush is free for 30 days. After that it's $19.99 a year, or $39.99 once. There is no extra charge for recipes.
