MyCreate Platform API

Platform API

The platform API allows you to read and write data to the Pi Servers related with your app deployed on the Pi App Platform, and your app's users.

Overview

Base path:

The latest version of the Platform API is available at api.minepi.com/v2.

Note about API versioning:

The platform API is currently in v2.
As much as possible, we will not make any breaking changes to a version of an API, and only release breaking changes as
new major versions. However, we might make breaking changes to an existing version without notice, if those are
necessary (e.g security or privacy fixes).

Authorization

The Platform API supports two different authorization mechanisms.

Access token authorization

Some API calls require that you provide a user's access token to access the resource. They are generally related with a user's data (e.g: /me). Those endpoints can be accessed using the following Authorization header:

Authorization: Bearer <user access token>

Those endpoints can be indifferently accessed from your backend / server app, or from your frontend / client app.

Server API Key authorization

For various reasons, some API calls must be made from your backend / server app. Those endpoints can be accessed using the following Authorization header:

Authorization: Key <your Server API Key>

Warning: Server API keys are for servers only

Your Server API Key must be kept on your server, and must not be sent to clients (do not use it in your
client javascript code).
In the future, your server API key might enable sensitive operations on your app itself that your users should
not be allowed to perform. Letting users access your server API key is a serious security breach.

API Reference

Authentication

Access a user's resource:

Retrieve the user's information, including user information limited to what the user has consented to share with your app.

GET /me

• Authorization method: Access token
• Response type: UserDTO

Verify the data obtained with the frontend SDK (a malicious user could tamper with the requests and send you wrong data) by sending the user’s access token to your backend and using this API endpoint to verify the token validity and the user’s identity.

Access tokens are long, random strings, and the request will fail (401 HTTP error code) if the token has been tampered with (a tampered token would
not belong to any real user).

Payments

There are two different payment types.

1. U2A (User-To-App)
2. A2U (App-To-User)

Create a payment (U2A):

If a payment type is U2A, use createPayment method of the client-side Javascript SDK to create a payment. You can refer to Payments section for more details.

Create a payment (A2U):

POST /payments

• Authorization method: Server API Key
• Response type: PaymentDTO

Example request body:

{
  "payment": {
    "amount": 1,
    "memo": "From app to user test",
    "metadata": {"test": "test metadata"},
    "uid": "a1111111-aaaa-bbbb-2222-ccccccc3333d"
  }
}

Get a payment:

Get information about a payment.

GET /payments/{payment_id}

• Authorization method: Server API Key
• Response type: PaymentDTO

Approve a payment:

Server-side approval: mark a payment as approved, enabling the user to submit the transaction to the blockchain.

POST /payments/{payment_id}/approve

• Authorization method: Server API Key
• Response type: PaymentDTO

Complete a payment:

Server-side completion: mark a payment as completed by proving to the Pi Servers that your app has obtained the payment's txid, enabling the user to close the payment flow.

POST /payments/{payment_id}/complete

• Authorization method: Server API Key
• Response type: PaymentDTO

Example request body:

{
  "txid": "7a7ed20d3d72c365b9019baf8dc4c4e3cce4c08114d866e47ae157e3a796e9e7"
}

Cancel a payment:

Mark the payment as cancelled.

POST /payments/{payment_id}/cancel

• Authorization method: Server API Key
• Response type: PaymentDTO

Get incomplete server payments:

Returns the list of server payments (i.e A2U payments) which are in EITHER one of the two states below:

• payment created, but no blockchain transaction was made yet ;
• blockchain transaction submitted, but the payment has not been completed by the developer.

GET /payments/incomplete_server_payments

• Authorization method: Server API Key
• Response type: { "incomplete_server_payments": Array<PaymentDTO> }

Ads

Verify a rewarded ad status

Verify status of a rewarded ad by adId returned by client Pi SDK method displayAd('rewarded')

GET /ads_network/status/:adId

• Authorization method: Server API Key
• Response type: RewardedAdStatusDTO
