Introduction

Welcome to Payger's Public API version 1.0-RELEASE.

This is an HTTP-based RESTful API and uses OAuth 2.0 for authentication and authorization.

API requests and responses are formatted in JSON.

Features for both Merchants and Wholesalers are available.

Authentication

To authenticate against Payger's Public API, you need a valid OAuth2 access token.

To get this token you will have to provide your Payger API key and secret.

Get a new token

Example Request (Get token):

curl -X POST https://merchants-api.payger.com/api/v1/oauth/token \
  -H 'Authorization: Basic dHdvaW1wdWxzZTpTRkRQZzU3YlZKWXliV1px' \
  -F grant_type=password \
  -F username=<username> \
  -F password=<password>

var request = require("request");

var options = { method: 'POST',
  url: 'https://merchants-api.payger.com/api/v1/oauth/token',
  headers: 
   { Authorization: 'Basic dHdvaW1wdWxzZTpTRkRQZzU3YlZKWXliV1px',
     'Content-Type': 'application/x-www-form-urlencoded'
    },
  formData: 
   { grant_type: 'password',
     username: 'merchant1',
     password: 'password1' } };

request(options, function (error, response, body) {
  if (error) throw new Error(error);

  console.log(body);
});

Example response (Get token):

{
    "access_token": "eyJhbG...",
    "token_type": "bearer",
    "refresh_token": "eyJhbG...",
    "expires_in": 9999999,
    "scope": "read",
    "organization": "PAYGER",
    "jti": "3a351273-b034-4856-a5a7-749f581c5be8"
}

To create a valid token call the OAuth2 token url:

POST /oauth/token

This resource uses Basic Authentication.

Follow these steps to retrieve an access token:

1) Concatenate your OAuth client name with a colon character ":", (leave the password empty!). Possible values for OAuth client are: "netevia", "payger" and "payger_wc_plugin"

2) Base64 encode the string from 1)

3) Include the resulting encoded string from 2) in an Authorization header as follows

Authorization: Basic <encoded string>

Request parameters

Parameter	Description	Value
`grant_type`	Type of grant	"password"
`username`	API Key	<API_KEY>
`password`	API Secret	<API_SECRET>

Alternative

As an alternative you can also pass these attributes as part of the url:

POST /oauth/token?grant_type=password&username=<API_KEY>&password=<API_SECRET>

The Authorization header is still required.

Upon valid API key/secret you will get an access_token that can be used in subsequent calls to the API, until it expires. When it does, please use the refresh_token to refresh it.

Refresh an existing token

Refresh tokens are tokens that can be used to replace expired access tokens without providing user credentials. These tokens are also subject to expiration.

Refresh tokens are issued when an access token is requested using Payger API user credentials (additionally, they are issued when requesting a new access token with a refresh token).

When requesting an access token using a refresh token you must use a grant type of refresh_token and provide the refresh token in the request body.

Request Parameters

Parameter	Description	Value
`grant_type`	grant type	"refresh_token"
`refresh_token`	refresh token as provided in the previous OAuth requests (New/Refresh)	<REFRESH_TOKEN>

Using a valid token

Upon successful token retrieval, the token can be used passing it as a Bearer token in the Authorization header, in all the calls to the MerchantsAPI endpoints:

Example:

GET https://merchants-api.payger.com/api/v1/merchants/balances/ Request Headers: Content-Type:"application/json" Authorization:"Bearer eyJhbG..."

API Details

Urls

Example (API Url):

https://merchants-api.payger.com/api/v1/merchants/balances

All the available urls are in the form https://merchants-api.payger.com/api/stage/resource and tipically the resource name is in the plural form (e.g. balances, payments, fees).

Metadata

Example:

"metadata":{
   "key1":"value1",
   "key2":"value2"
}

Some objects such as Payment and Merchant accept a parameter of type Object with additional object metadata in the format of key, value pairs.

The format is:

Field	Type	Format
Key	String	max length: 255
Value	String	max length: 255

Callback (feature not available yet)

Example:

"callback":{
   "url":"http://my.callback.url",
   "method":"POST"
}

Some objects such as Payment accept an attribute of type Callback enabling the possibility to declare an url/method to be called anytime there is change in the object status or in any other key attribute change.

The format is:

Field	Type	Format
url	String	max length: 2000
method	String	One of POST, PUT, DELETE or GET

The callback request is made passing a pgr-payment-id header to identify the payment.

The callback mechanism uses the following retry policy: maximum of 5 attemps, 2 seconds between each attempt.

Pagination and Sorting

Some endpoints that might return extense sets of data, such as /merchants/payments and /merchants/transactions/ accept pagination and sorting parameters.

These parameters are passed as part of the url:

Parameter	Description	Examples	Default
page	Page index	page=0 (first page)	0
size	Max number of results per request	size=50	10
sort	field(s) to apply sorting when returning results	sort=created,DESC - sorts by descending creation date sort=created,DESC&sort=externalId,ASC - sorts by descending creation date and ascending externalId	sort=created,ASC - sorts by ascending creation date

You can apply more than one filter by adding more url parameters.

Example: sort=created,DESC&sort=status&size=100

Example 1 (Pagination/PageNumber):

https://merchants-api.payger.com/api/v1/merchants/payments?page=5

Example 2 (Pagination/PageSize):

https://merchants-api.payger.com/api/v1/merchants/transactions?size=50

Example 3 (Pagination and Sort):

https://merchants-api.payger.com/api/v1/merchants/transactions?page=2&size=20&sort=created,ASC&sort=status,DESC

Response (Pagination and Sort Transactions):

{
   "content":[
      {
         "id":"transaction1",
         "externalRef":"payment1",
         "description":"description1",
         "type":"PAYMENT",
         "status":"NEW",
         "merchantId":"merchant1",
         "timestamp":"2018-04-11 16:02:33"
      },
      {
         "id":"transaction2",
         "externalRef":"payment2",
         "description":"description2",
         "type":"PAYMENT",
         "status":"NEW",
         "merchantId":"merchant1",
         "timestamp":"2018-04-11 16:02:33"
      }
   ],
   "size": 20,
   "page": 2,
   "pageElements": 2
}

Limitations (feature not available yet)

To ensure consistent access to API resources and prevent abuse that can impact performance for all users, all endpoints have rate limits in place. These limits are applied by user account (Token).

Each Token will be limited to NNNN requests per hour.

Idempotent requests

Example (Idempotent Request):

curl -X POST \
  https://merchants-api.payger.com/api/v1/merchants/payments/ \
  -H 'Authorization: Bearer eyJ...' \
  -H 'Content-Type: application/json' \
  -H 'pgr-idempotency: cbdd64d5-8493-404e-909c-b118d8caa0ef' \
  -d '{
   "externalId":"ext12345",
   "description":"description",
   "paymentCurrency":"BTC",
   "productCurrency":"USD",
   "source":"string",
   "productAmount":"0.003",
   "buyerName":"buyer",
   "buyerEmailAddress":"test@test.com",
   "ipAddress":"10.10.10.1",
   "latitude":"12.3211",
   "longitude":"-11.585274",
   "callback":{
      "url":"http://demo.com",
      "method":"POST",
      "params":{
         "orderID":"12345"
      }
   },
   "metadata":{
      "a":"b"
   }
}'

As a safety feature, this API supports an Idempotency Identifier in all the relevant requests: POST and PUT.

This will allow the user to safely retry the same request twice, obtaining the same response, if the same Idempotency Identifier is passed. This may happen due to some code error, network error, JMS or Database rollback, etc. In this case, if using the Idempotency Identifier, the API garantees that the request is executed once only.

To perform an idempotent request, provide an additional pgr-idempotency header to the request. The maximum lenght is 40. Anything above will result in an HTTP error code 400.

If not using the Idempotency Identifier, or passing a blank value, all the relevant requests will always be processed.

Please use random strings and do not repeat. We suggest UUID's or some equivalent unique identifier generation algorithm.

At the moment these IDs do not expire.

You can safely retry your requests by adding a pgr-idempotency header.

POST /merchants/payments

The API will generate a new payment object and call PAYGER's backend to initiate a payment operation. The corresponding paymentAmount is calculated applying the current exchange rate for the conversion productCurrency>paymentCurrency for the required amount, plus fees (see Fee object returned by the API). A new qrCode with the payment address is returned to the user, so he is able to transfer the funds.

Fields id, status, merchantId, created, lastUpdated, fee and subPayments list will be returned automatically by the API.

Update a payment

PUT /merchants/payments/{id}

The API will update the existing payment object with new description, externalId and metadata.

Field lastUpdated will be set automatically by the API.

Example request (Update a payment):

"PUT https://merchants-api.payger.com/api/v1/merchants/payments/"
{
    "externalId": "EXTERNAL_ID",
    "description" : "new description",

How-To

Create a new payment (Merchants)

Example: Suppose I own an ECommerce website, and I have a valid Merchant account with Payger. I'm working with US Dollars (USD) and I want to sell a product worth 100 US Dollars, accepting a Bitcoin (BTC) payment.

To use this API to accept the payment I must:

1 - Get a valid API key/secret

Access Payger Wallet to generate a new API key/secret pair.

2 - Get a new API token

With this pair (key/secret) call the url

POST /oauth/token?grant_type=password&username=<API_KEY>&password=<API_SECRET>

Using Basic HTTP authentication.

The OAuth client auth should be: Username: "netevia", "payger" or "payger_wc_plugin". Password: Empty string

Get the valid token from the attribute access_token

This token must be used in all subsequent calls, as a Bearer authorization token.

3 - Get a quote

Call the ExchangeRates endpoint to get a quote for the currency conversion:

GET /merchants/exchange-rates?productCurrency=<PRODUCT_CURRENCY>&paymentCurrency=<PAYMENT_CURRENCY>&amount=<AMOUNT>

Parameter	Description	Value
`productCurrency`	Currency in which we are currently selling the product on our website	US Dollars (USD)
`paymentCurrency`	Currency in which the payment will be accepted	Bitcoin (BTC)
`amount`	Amount	100

URL:

GET /merchants/exchange-rates?productCurrency=USD&amount=100&paymentCurrency=BTC

Example response (Get Exchange Rate):

{
    "content": {
        "rates": [
            {
                "currency": "BTC",
                "rate": "0.00017028060000000002",
                "amount": "0.01702806",
                "precision": 8
            }
        ],
        "productCurrency": "USD",
        "amount": "100"
    },
    "timestamp": "2018-08-17 15:01:53"
}

The amount is just a quote that Payger API provides to the user to buy bitcoin worth of 100 USD. This quote should be displayed to the user when creating the UI payment button.

Make sure that your payment amount is not greater than the limit returned, or your payment cannot be accepted.

4 - Get the fee amount (optional)

Call the Fees endpoint to get an estimated Fee amount. This can be presented to the user as this amount will be included in the total amount of the payment. Later when creating the payment, the final Fee amount will be provided.

POST /merchants/fees/

Example request (Get Fee):

{
  "paymentCurrency": "BTC",
  "productAmount": "100",
  "productCurrency": "USD"
}

Example response (Get Fee):

{
    "content": {
        "feeInProductCurrency": {
            "currency": "USD",
            "fee": "0.009036472509526402"
        },
        "feeInPaymentCurrency": {
            "currency": "BTC",
            "fee": "0.00000166"
        }
    },
    "timestamp": "2018-09-06 15:21:55"
}

5 - Create the payment request

Call the Payments endpoint to initiate a new payment. Reuse the same productCurrency and productAmount.

               "fileType":"png",
               "encoding":"UTF-8"
            },

            "longitude":"-11.585274",
            "status":"pending"
         }
      ],
      "fee":{
            "feeInProductCurrency":{
                "currency":"USD",
                "fee":"0.0008924731182795699"
            },
            "feeInPaymentCurrency":{
                "currency":"BTC",
                "fee":"0.00000166"
            }
      },
      "source":"string",
      "buyerName":"buyerName",
      "buyerEmailAddress":"test@test.com"
   },
   "timestamp":"2018-08-17 15:25:36"
}

The payment is created with a status of PENDING and until the API receives the payment notification this will be the payment status.

Important information to retain:

Field	Description
`id`	The payment unique identifier
`subPayments.qrCode`	Use this qrCode as a reference to transfer to funds to
`status`	Immediatly after creation the status of the payment is `PENDING`, later should change to `PAID`
`fee`	Fees applied (converted to both currencies)

Keep the payment id for future reference (cb84dee0-a231-11e8-83f4-f39d574b416d).

The qrCode object contains the new qrCode contents (encoded image) and qrCode meta information. Use this information to render the qrCode on the page so as the user can scan it and use it to transfer the funds.

6 - Check the payment status

Call the Payments endpoint with the payment id obtained in the previous step to get the current payment status.

GET /merchants/payments/{id}

After the API receives payment notification the subPayments attribute will return indication that the payment has been made by the user, using the reference in the qrCode. The payment status should then be PAID.

Can take several minutes since the funds are transferred until the payment is detected by the API. If any discrepancy is found the status of the payment can be UNDERPAID or OVERPAID. Underpaid payments allow generation of a new payment address to compensate the unsuficient amount. Overpaid payments are to be resolved manually by the Merchant. The algorithm applies a tolerance of 2% of the payment amount. The payment will be marked as EXPIRED after 15 minutes without any actions.

After 15 minutes the payment is marked as EXPIRED but can be changed back to PAID if a new payment address is requested (calling POST /merchants/payments/{id}/address)

Example request (Get Payment):

GET /merchants/payments/cb84dee0-a231-11e8-83f4-f39d574b416d

7 - Confirm

In case of successfuly processed payment, the funds are transferred into your merchant PAYGER account.

8 - Callback

If the callback was set, please make sure the url is available to get notifications of any changes in the Payment object.
