Initialize the SDK 20 | ```javascript 21 | import PiNetwork from 'pi-backend'; 22 | 23 | // DO NOT expose these values to public 24 | const apiKey = "YOUR_PI_API_KEY" 25 | const walletPrivateSeed = "S_YOUR_WALLET_PRIVATE_SEED" // starts with S 26 | const pi = new PiNetwork(apiKey, walletPrivateSeed); 27 | ``` 28 | 29 | 2. Create an A2U payment 30 | 31 | Make sure to store your payment data in your database. Here's an example of how you could keep track of the data. 32 | Consider this a database table example. 33 | 34 | | uid | product_id | amount | memo | payment_id | txid | 35 | | :---: | :---: | :---: | :---: | :---: | :---: | 36 | | `userUid` | apple-pie-1 | 3.14 | Refund for apple pie | NULL | NULL | 37 | 38 | ```javascript 39 | const userUid = "user_uid_of_your_app" 40 | const paymentData = { 41 | amount: 1, 42 | memo: "Refund for apple pie", // this is just an example 43 | metadata: {productId: "apple-pie-1"}, 44 | uid: userUid 45 | } 46 | // It is critical that you store paymentId in your database 47 | // so that you don't double-pay the same user, by keeping track of the payment. 48 | const paymentId = await pi.createPayment(paymentData); 49 | ``` 50 | 51 | 3. Store the `paymentId` in your database 52 | 53 | After creating the payment, you'll get `paymentId`, which you should be storing in your database. 54 | 55 | | uid | product_id | amount | memo | payment_id | txid | 56 | | :---: | :---: | :---: | :---: | :---: | :---: | 57 | | `userUid` | apple-pie-1 | 3.14 | Refund for apple pie | `paymentId` | NULL | 58 | 59 | 4. Submit the payment to the Pi Blockchain 60 | ```javascript 61 | // It is strongly recommended that you store the txid along with the paymentId you stored earlier for your reference. 62 | const txid = await pi.submitPayment(paymentId); 63 | ``` 64 | 65 | 5. Store the txid in your database 66 | 67 | Similarly as you did in step 3, keep the txid along with other data. 68 | 69 | | uid | product_id | amount | memo | payment_id | txid | 70 | | :---: | :---: | :---: | :---: | :---: | :---: | 71 | | `userUid` | apple-pie-1 | 3.14 | Refund for apple pie | `paymentId` | `txid` | 72 | 73 | 6. Complete the payment 74 | ```javascript 75 | const completedPayment = await pi.completePayment(paymentId, txid); 76 | ``` 77 | 78 | ## Overall flow for A2U (App-to-User) payment 79 | 80 | To create an A2U payment using the Pi Node.js SDK, here's an overall flow you need to follow: 81 | 82 | 1. Initialize the SDK 83 | > You'll be initializing the SDK with the Pi API Key of your app and the Private Seed of your app wallet. 84 | 85 | 2. Create an A2U payment 86 | > You can create an A2U payment using `createPayment` method. This method returns a payment identifier (payment id). 87 | 88 | 3. Store the payment id in your database 89 | > It is critical that you store the payment id, returned by `createPayment` method, in your database so that you don't double-pay the same user, by keeping track of the payment. 90 | 91 | 4. Submit the payment to the Pi Blockchain 92 | > You can submit the payment to the Pi Blockchain using `submitPayment` method. This method builds a payment transaction and submits it to the Pi Blockchain for you. Once submitted, the method returns a transaction identifier (txid). 93 | 94 | 5. Store the txid in your database 95 | > It is strongly recommended that you store the txid along with the payment id you stored earlier for your reference. 96 | 97 | 6. Complete the payment 98 | > After checking the transaction with the txid you obtained, you must complete the payment, which you can do with `completePayment` method. Upon completing, the method returns the payment object. Check the `status` field to make sure everything looks correct. 99 | 100 | ## SDK Reference 101 | 102 | This section shows you a list of available methods. 103 | ### `createPayment` 104 | 105 | This method creates an A2U payment. 106 | 107 | - Required parameter: `PaymentArgs` 108 | 109 | You need to provide 4 different data and pass them as a single object to this method. 110 | ```typescript 111 | type PaymentArgs = { 112 | amount: number // the amount of Pi you're paying to your user 113 | memo: string // a short memo that describes what the payment is about 114 | metadata: object // an arbitrary object that you can attach to this payment. This is for your own use. You should use this object as a way to link this payment with your internal business logic. 115 | uid: string // a user uid of your app. You should have access to this value if a user has authenticated on your app. 116 | } 117 | ``` 118 | 119 | - Return value: `a payment identifier (paymentId: string)` 120 | 121 | ### `submitPayment` 122 | 123 | This method creates a payment transaction and submits it to the Pi Blockchain. 124 | 125 | - Required parameter: `paymentId` 126 | - Return value: `a transaction identifier (txid: string)` 127 | 128 | ### `completePayment` 129 | 130 | This method completes the payment in the Pi server. 131 | 132 | - Required parameter: `paymentId, txid` 133 | - Return value: `a payment object (payment: PaymentDTO)` 134 | 135 | The method return a payment object with the following fields: 136 | 137 | ```typescript 138 | payment: PaymentDTO = { 139 | // Payment data: 140 | identifier: string, // payment identifier 141 | user_uid: string, // user's app-specific ID 142 | amount: number, // payment amount 143 | memo: string, // a string provided by the developer, shown to the user 144 | metadata: object, // an object provided by the developer for their own usage 145 | from_address: string, // sender address of the blockchain transaction 146 | to_address: string, // recipient address of the blockchain transaction 147 | direction: Direction, // direction of the payment ("user_to_app" | "app_to_user") 148 | created_at: string, // payment's creation timestamp 149 | network: string, // a network of the payment ("Pi Network" | "Pi Testnet") 150 | // Status flags representing the current state of this payment 151 | status: { 152 | developer_approved: boolean, // Server-Side Approval (automatically approved for A2U payment) 153 | transaction_verified: boolean, // blockchain transaction verified 154 | developer_completed: boolean, // Server-Side Completion (handled by the create_payment! method) 155 | cancelled: boolean, // cancelled by the developer or by Pi Network 156 | user_cancelled: boolean, // cancelled by the user 157 | }, 158 | // Blockchain transaction data: 159 | transaction: null | { // This is null if no transaction has been made yet 160 | txid: string, // id of the blockchain transaction 161 | verified: boolean, // true if the transaction matches the payment, false otherwise 162 | _link: string, // a link to the operation on the Pi Blockchain API 163 | } 164 | } 165 | ``` 166 | 167 | ### `getPayment` 168 | 169 | This method returns a payment object if it exists. 170 | 171 | - Required parameter: `paymentId` 172 | - Return value: `a payment object (payment: PaymentDTO)` 173 | 174 | ### `cancelPayment` 175 | 176 | This method cancels the payment in the Pi server. 177 | 178 | - Required parameter: `paymentId` 179 | - Return value: `a payment object (payment: PaymentDTO)` 180 | 181 | ### `getIncompleteServerPayments` 182 | 183 | This method returns the latest incomplete payment which your app has created, if present. Use this method to troubleshoot the following error: "You need to complete the ongoing payment first to create a new one." 184 | 185 | - Required parameter: `none` 186 | - Return value: `an array which contains 0 or 1 payment object (payments: Array)` 187 | 188 | If a payment is returned by this method, you must follow one of the following 3 options: 189 | 190 | 1. cancel the payment, if it is not linked with a blockchain transaction and you don't want to submit the transaction anymore 191 | 192 | 2. submit the transaction and complete the payment 193 | 194 | 3. if a blockchain transaction has been made, complete the payment 195 | 196 | If you do not know what this payment maps to in your business logic, you may use its `metadata` property to retrieve which business logic item it relates to. Remember that `metadata` is a required argument when creating a payment, and should be used as a way to link this payment to an item of your business logic. 197 | 198 | ## Troubleshooting 199 | 200 | ### Error when creating a payment: "You need to complete the ongoing payment first to create a new one." 201 | 202 | See documentation for the `getIncompleteServerPayments` above. 203 | 204 | -------------------------------------------------------------------------------- /docs/swagger.js: -------------------------------------------------------------------------------- 1 | const swaggerJsDoc = require('swagger-jsdoc');
