Supported runtimes

  • Node 6, 8, 10

Dependencies

  • None

Usage

npm install @button/button-client-node

To create a client capable of making network requests, invoke button-client-node with your API key.

const client = require('@button/button-client-node')('sk-XXX');

You can optionally supply a config argument with your API key:

const client = require('@button/button-client-node')('sk-XXX', {
  timeout: 3000, // network requests will time out at 3 seconds
  hostname: 'api.usebutton.com' // default hostname for api requests
});
Config
  • timeout: The time in ms for network requests to abort. Defaults to false.
  • hostname: Defaults to api.usebutton.com
  • port: Defaults to 443 if config.secure, else defaults to 80.
  • secure: Whether or not to use HTTPS. Defaults to true. N.B: Button's API is only exposed through HTTPS. This option is provided purely as a convenience for testing and development.

Promise

button-client-node uses native Promises for all requests:

const client = require('@button/button-client-node')('sk-XXX', {
  timeout: 3000
});

client.orders.get('btnorder-XXX')
  .then(handleResult)
  .catch(handleError);

The returned promise will either reject with an Error or resolve with the API response object.

Responses

All responses will assume the following shape:

{
  data,
  meta: {
    next,
    previous
  }
}

The data key will contain any resource data received from the API and the meta key will contain high-order information pertaining to the request.

meta
  • next: For any paged resource, next will be a cursor to supply for the next page of results.
  • previous: For any paged resource, previous will be a cursor to supply for the previous page of results.

Resources

We currently expose the following resources to manage:

Accounts

All
const client = require('@button/button-client-node')('sk-XXX');

client.accounts.all()
  .then(handleResult)
  .catch(handleError);
Transactions

Transactions are a paged resource. The response object will contain properties meta.next and meta.previous which can be supplied to subsequent invocations of #transactions to fetch additional results.

#transactions accepts an optional second parameter, options which may define the follow keys to narrow results:

options
  • cursor: An API cursor to fetch a specific set of results
  • start: An ISO-8601 datetime string to filter only transactions after start
  • end: An ISO-8601 datetime string to filter only transactions before end
  • time_field: Which time field start and end filter on.
const client = require('@button/button-client-node')('sk-XXX');

// without options argument
//
client.accounts.transactions('acc-1')
  .then(handleSuccess)
  .catch(handleError);

// with options argument
//
client.accounts.transactions('acc-1', {
  cursor: 'cXw',
  start: '2015-01-01T00:00:00Z',
  end: '2016-01-01T00:00:00Z',
  time_field: 'modified_date'
}).then(handleResult)
  .catch(handleError);

Merchants

All
options
  • status: Partnership status to filter by. One of ('approved', 'pending', or 'available')
  • currency: ISO-4217 currency code to filter returned rates by
const client = require('@button/button-client-node')('sk-XXX');

// without options argument
//
client.merchants.all()
  .then()
  .catch();

// with options argument
//
client.merchants.all({
  status: 'pending',
  currency: 'USD'
}).then(handleResult)
  .catch(handleError);

Orders

Create
const crypto = require('crypto');
const client = require('@button/button-client-node')('sk-XXX');

const hashedEmail = crypto.createHash('sha256')
  .update('user@example.com'.toLowerCase().trim())
  .digest('hex');

client.orders.create({
  total: 50,
  currency: 'USD',
  order_id: '1989',
  purchase_date: '2017-07-25T08:23:52Z',
  finalization_date: '2017-08-02T19:26:08Z',
  btn_ref: 'srctok-XXX',
  customer: {
    id: 'mycustomer-1234',
    email_sha256: hashedEmail
  }
}).then(handleResult)
  .catch(handleError);
Get
const client = require('@button/button-client-node')('sk-XXX');

client.orders.get('btnorder-XXX')
  .then(handleResult)
  .catch(handleError);
Get by Button Ref
const client = require('@button/button-client-node')('sk-XXX');

client.orders.getByBtnRef('srctok-XXX')
  .then(handleResult)
  .catch(handleError);
Update
const client = require('@button/button-client-node')('sk-XXX');

client.orders.update('btnorder-XXX', { total: 60 })
  .then(handleResult)
  .catch(handleError);
Delete
const client = require('@button/button-client-node')('sk-XXX');

client.orders.del('btnorder-XXX')
  .then(handleResult)
  .catch(handleError);

Customers

Create
const crypto = require('crypto');
const client = require('@button/button-client-node')('sk-XXX');

const hashedEmail = crypto.createHash('sha256')
  .update('user@example.com'.toLowerCase().trim())
  .digest('hex');

client.customers.create({
  id: 'customer-1234',
  email_sha256: hashedEmail
}).then(handleResult)
  .catch(handleError);
Get
const client = require('@button/button-client-node')('sk-XXX');

client.customers.get('customer-1234')
  .then(handleResult)
  .catch(handleError);

Links

Create
client.links.create({
  url: "https://www.jet.com",
  experience: {
    btn_pub_ref: "my-pub-ref",
    btn_pub_user: "user-id"
  }
}).then(handleResult)
  .catch(handleError);
Get Info
client.links.getInfo({ url: "https://www.jet.com" })
  .then(handleSuccess)
  .catch(handleError);

Transactions

All

Transactions are a paged resource. The response object will contain properties meta.next and meta.previous which can be supplied to subsequent invocations of #all to fetch additional results.

Unlike the accounts.transaction resource, which only queries a single account's transactions, the transactions.all resource queries all of an organizations transactions.

#all accepts an optional second parameter, options which may define the follow keys to narrow results:

options
  • cursor: An API cursor to fetch a specific set of results
  • start: An ISO-8601 datetime string to filter only transactions after start
  • end: An ISO-8601 datetime string to filter only transactions before end
  • time_field: Which time field start and end filter on.
const client = require('@button/button-client-node')('sk-XXX');

// without options argument
//
client.transactions.all()
  .then(handleSuccess)
  .catch(handleError);

// with options argument
//
client.transactions.all({
  cursor: 'cXw',
  start: '2015-01-01T00:00:00Z',
  end: '2016-01-01T00:00:00Z',
  time_field: 'modified_date'
}).then(handleResult)
  .catch(handleError);

Utils

Utils houses generic helpers useful in a Button Integration.

#isWebhookAuthentic

Used to verify that requests sent to a webhook endpoint are from Button and that their payload can be trusted. Returns true if a webhook request body matches the sent signature and false otherwise. See Webhook Security for more details.

Example usage with body-parser

const express = require('express');
const bodyParser = require('body-parser');
const utils = require('@button/button-client-node').utils

const app = express();

function verify(req, res, buf, encoding) {
  const isAuthentic = utils.isWebhookAuthentic(
    process.env['WEBHOOK_SECRET'],
    buf,
    req.headers['X-Button-Signature']
  );

  if (!isAuthentic) {
    throw new Error('Invalid Webhook Signature');
  }
}

app.use(bodyParser.json({ verify: verify, type: 'application/json' }));
