Overview

Webhooks let you stay up-to-date with any new data added, updated, or deleted in real-time. For example, when the user connects a new payroll account, Argyle will immediately call an HTTP endpoint on your system to let you know about the event.

You can find the full list of webhook events in this Webhooks reference.

Argyle webhooks are delivered from four static IP addresses:

• 34.27.251.226
• 34.122.50.253
• 35.188.163.115
• 35.226.53.251

Subscribe to webhooks using the API

The webhook events you subscribe to are delivered for all accounts. Each time a new account is connected or an existing one is updated, a corresponding webhook will notify your system.

You can subscribe to webhooks by sending a POST request to Argyle's webhooks endpoint with the event name you want to subscribe to. This Webhooks reference contains the list of examples for all webhook subscription calls.

To subscribe to all webhooks, use an asterisk for events: "events": "*".

curl -X POST https://api-sandbox.argyle.com/v1/webhooks \
  -u api_key_id:api_key_secret \
  -H "Content-Type: application/json" \
  -d '{"events": ["activities.fully_synced"],
       "secret": "<secret for signature verification>",
       "name": "name-of-the-webhook",
       "url": "https://mybackend.com/callback/argyle"}'

While optional, we suggest choosing a random value for the secret parameter when subscribing to webhooks. You will use this value during signature validation to determine the authenticity of the webhook.

For example, if you subscribe to the activities.fully_synced event, every time all activities have finished syncing during the initial scan, the specified url will be invoked with the json payload specific to that event.

Here is an example payload for activities:

{
    "event": "activities.fully_synced",
    "name": "Fully synced",
    "data": {
        "account": "12db5af4-fd5f-4d1f-bd98-0360df770aa8",
        "user": "abdb5af4-fd5f-4d1f-bd10-0360df77012c",
        "available_from": "2017-07-15T00:00:00",
        "available_to": "2019-10-01T15:47:00",
        "available_count": 324
    }
}

Subscribe to webhooks using Console

Visit the Webhooks tab in the Developers section of Console to view and manage your existing webhook subscriptions as well as create new ones.

Signature validation

When you subscribe to a webhook, you may choose to include a secret to ensure the authenticity of the webhooks you receive. If you do, each webhook you receive will include a signature in the header that you can use to verify that the webhook is genuine.

To verify the authenticity of a webhook, directly encode the received payload body without any added adjustments by using HMAC-SHA512 with the secret that you provided when subscribing to the webhook as the secret key. If the encoded payload matches the signature in the header, you can be confident that the webhook and its payload are genuine.

Example

If your secret was my little secret, you would expect the following signature:

'X-Argyle-Signature': '13b68c651cdf714d8d00e88d3c9997d2ea2cb6ffcc57ba2d9164af5898169124e75505f354ded4350c96b03b2cddf01cbe71bc26cb2dc656a69ef670bcda0f86'

For the following body:

{"name": "Account added", "event": "accounts.added"}

Below is an example in Node:

const http = require('http');
const crypto = require('crypto');

const serverPort = 80
const requestListener = function (req, res) {
  // the client secret is being configured when a webhook is created
  const client_secret = 'my little secret';
  var requestBody = '';
  req.on('readable', () => {
    var read = req.read()
    if(read != null) {
    requestBody += read;
    }
  });
  req.on('end', () => {
    jsonBody = JSON.stringify(requestBody);
    // do whatever you need with jsonBody, however use requestBody in the signature payload
    signature = crypto.createHmac('sha512',client_secret).update(requestBody).digest('hex');
  console.log('Signature:' + signature);
  res.writeHead(200);
  res.end(signature);
  })
}
const server = http.createServer(requestListener);
server.listen(serverPort);

Argyle webhooks are currently delivered from four static IP addresses:

• 34.27.251.226
• 34.122.50.253
• 35.188.163.115
• 35.226.53.251

Verifying authenticity via these IPs is not recommended and should only be used as a fallback method because these addresses could change in the future.

Account connection status

If an account becomes disconnected, some events will not trigger their associated webhook until the account connection is re-established.

Check the account object's connection.status attribute to see if an account is connected.

You can also subscribe to the accounts.updated webhook to be notified when an account becomes disconnected, as the account object's connection.status changing from connected to error triggers the accounts.updated webhook. When subscribing to the accounts.updated webhook, settinginclude_resource to true allows you to view the account object directly in the webhook payload.

Use case: keeping all activities on your system in sync

Here is how webhooks can help you to have all activity data downloaded on your own servers, and keep it in sync with the Argyle API:

1. Subscribe to activities.fully_synced to get notified when the initial account sync of all historical data is finished. Whenever the webhook is invoked, query the activities from the API with the following query: /activities?from_start_date=available_from&account=account_id&to_start_date=available_to where account is the account ID, and available_from and available_to are timestamps from the webhook payload.
2. Subscribe to activities.added to get notified when new activities are added after the initial sync. Argyle scans all accounts periodically for new activities and other changes in data. Use the same API call, but with added_from and added_to timestamps from the webhook payload.
3. Subscribe to activities.updated to get notified when existing activities change. An example of this would be when additional information about a completed activity is passed along at a later time (e.g. tips for a completed delivery or ride). The webhook payload provides the date range that was updated (updated_from and updated_to) along with an array of activity IDs that were updated (updated_activities) to make syncing of the data more convenient.
4. Subscribe to activities.removed to get notified when activities are removed by a payroll provider. This webhook is an indication to make sure that the activities are removed from your database to avoid duplicate data for a specific account. The webhook payload provides the date range when activities were removed (removed_from and removed_to), the number of activities that were removed (removed_count), along with an array of activity IDs that were removed (removed_activities).
