API overview

General information

The Coinsbuy API v3 is organized in accordance with JSON API paradigm. For a better understanding of the paradigm principles, read the JSON API Specification.

We use conventional HTTP response codes, OAuth 2.0 protocol for authentication, and HMAC-SHA256 algorithm for encryption.

Except for Authentication, all requests must contain the following HTTP headers:

• Authorization: Bearer {YOUR_ACCESS_TOKEN}: Used to authenticate your request.
• Content-Type: application/vnd.api+json: Required according to JSON API Specification.

Filtering

Filters by object parameters can be applied to any GET-method according to the JSON API Specification.

Callbacks

The Coinsbuy API also provides flexible options for callback — an asynchronous notification about changing statuses of deposits and payouts. To learn more, refer to Callback.

To receive callbacks, specify a callback URL when sending a Create deposit or Create payout request. When a transaction receives the required number of confirmation blocks, the callback is sent via an HTTP POST-request to the specified URL. If you also want to be notified when the number of confirmations received for a transaction doesn’t reach a specific threshold or exceeds it, indicate the required number of confirmations in the request.

Date-time values

All date-time values are specified as per ISO 8601-1:2019, with milliseconds precision and timezone included: YYYY-MM-DDThh:mm:ss[.SSSSSS]±hh:mm.

Destination object

The object contains the following fields:

• address_type (string or null)
  For wallets denominated in BTC, LTC, BCH, XRP: the address type. Refer to Address types for supported values.
  For other wallets the value is null.
• address (string)
  The deposit address.
  For payments in XRP, an array of objects is returned containing the x-address and address (with a destination tag additionally specified):

"destination": [
  {
    "address_type": "x-address",
    "address": "X7dBkB9KmvUh6GGHbjhxdu4LfkwhJ74oVWbGRoy7VLnHdJ6"
  },
  {
    "address_type": "address",
    "address": "rsxXXvBXmKUkCyCeNCHUFpfCX9pQdxQhv5",
    "tag": "0"
  }
]

For payments in XLM, the destination object is as follows:

"destination": {
  "address_type": "address",
  "address": "GCZJFWB5NVQHVBMV4U6CCJIXXBGINGYF2W33PMD5REBD5VQ6H6BLCJR5",
  "tag_type": 0,
  "tag": ""
}

where:

• address_type is always "address".
• address is a string value containing the wallet address.
• tag_type is a number value containing tag or memo type. Possible values:
  • 0 — no memo
  • 1 — a 64-bit unsigned integer
• tag is a string value containing the tag.
