Data Syncs

Finch syncs data for Automated providers on a 24-hour cadence and for Assisted providers on a 7-day cadence. Finch API responses will return data from the most recent successful sync. Performing data syncs in this way ensures that latency for all Finch API requests should remain under 200ms.

After an employer authorizes your application through Finch Connect, Finch will enqueue an initial data fetch job which will fetch all relevant data for the employer connection. For automated providers, if you attempt to request data before the initial sync has completed, Finch will request live data from the provider. Live request latencies may range from several seconds to minutes for large batch sizes. Once the initial data sync has completed, Finch API responses will return the synced data.

You can use several Finch response headers to determine the freshness of the data you receive:

​

Batch requests

For batch endpoints (/employment, /individual, /pay-statement) Finch syncs all of the data for the connection in one atomic operation. This ensures that all items in the batch response you receive are from the same data sync.

​

Pay statements

Generally, Finch currently fetches pay statements from the start of 2020. However, there are certain providers with restrictions for which Finch can fetch data for shorter time periods. These include:

• Paychex Flex: 14 months of pay statement data
• Paycom: 2 years of pay statement data

Because there is significantly more pay statement data than payment data, it may be the case that individual pay statements take much longer to fetch than payments. Therefore if you have received a payment_id from the /payment endpoint, and try to use it in a /pay-statement request, it is possible the pay statement has not been fetched yet. In this case, Finch will return a 202 in the body of the /pay-statement request. The response will look like this:

{
  "responses": [
    {
      "payment_id": "9c8626e3-6d97-48a0-883c-f4c65e736321",
      "code": 202,
      "body": {
        "code": 202,
        "name": "accepted",
        "finch_code": "data_sync_in_progress",
        "message": "The pay statements for this payment are being fetched. Please check back later."
      }
    },
    ...
  ]
