To be able to test and integrate your application, you first need to write your application Manifest file.
This file must contain some mandatory information, such as the app package names, the components, the permissions needed, the hardware and software features, etc.
Example of Manifest (JSON format) for Moonpay application:
{
"id": "moonpay",
"name": "Moonpay",
"url": "https://buy.moonpay.com",
"homepageUrl": "https://www.moonpay.com",
"icon": "https://cdn.live.ledger.com/icons/platform/moonpay.png",
"platform": "all",
"apiVersion": "2.0.0",
"manifestVersion": "1",
"branch": "stable",
"categories": ["buy"],
"currencies": [
"bitcoin",
"ethereum"
],
"content": {
"shortDescription": {
"en": "A fast, simple, and secure way to buy crypto."
},
"description": {
"en": "MoonPay accepts all major payment methods and over 30 fiat currencies, enabling people from all over the world to buy crypto."
}
},
"permissions": [],
"domains": [
"https://*"
]
}
Here is the list of the mandatory fields required in your Manifest file:

Type: string.name: the name of your application (“Moonpay” in this example).
