How to Setup a Check Printing API?

With a growing economy, businesses must remain competitive and quickly get up to speed to attract consumers. Accountants must pay corporate vendors, and your most valuable commodity, company time, is precious. With an online payroll outsourcing system, you can get ahead in the race by having online check mailing capabilities. By fully automating your services, printing checks, and accepting payments faster, you can free up time for your accountants and employees to pursue other productive tasks. 

Payroll Processing 

When you setup an API, you’ll be able to fully use your mailing capabilities. Developers will determine your needs. Then, they’ll fully implement and merge the check writing software with your current desktop applications, so it’ll be easy for you to make the transition to the system. 
With this process, you can authorize and print checks online 24 hours per day, seven days a week, through the check-issuing server. You can set up your computer systems to print your checks on premium-grade industrial printing paper. All of this will make your payroll processing much more efficient, saving you time and resources. 


APIs, or Application Programmable Interfaces, interact with multiple applications while making your check writing responsibilities seamlessly. 
You may have visited a store recently to purchase goods. Maybe you bought a computer printer and printing paper and paid for the products at the cash register. You weren’t responsible for knowing all the business operations and specialty departments that must exist to make your purchase possible. 
The store where you purchased the product was responsible for ordering the product, entering the product specifications in the computer, and putting the product on the shelf—all while simultaneously paying for employees and overhead costs. 
In the same manner, the check-printing application interface takes over all the functions of check printing, so you can focus solely on your clients while paying business invoices. 
The check-printing application interface will assist you in interloping your back-office systems with our corporate mainframe servers. The software integration will notify us once you make deposits, access general account information, submit check payments for processing, and make sure those payments are posted to your account when you setup an API. 
APIs do the following:

  • Access data from a third-party
  • Hide complex duties while performing tasks
  • Interact with different operating systems like Apple and Microsoft
  • Demonstrate functionality
  • Provide a safe and secure gateway

Check Printing API

The good news is you don’t have to be a computer science engineer to use API code. Everything is included in your API online check-printing package.
Check printing API services let you: 

  • Mail checks 
  • Request that paid checks be returned to you in PDF format
  • Get access to multiple delivery options like FedEx, UPS, or USPS
  • Attach documentation to outbound checks as necessary


Before you start to use online check-printing services, you’ll need to set up and establish your account. The first time you access the software, you’ll need an authorization token for check fulfillment. With this authorization, you can fulfill check orders and get the status of each check request. 

How to Get Started 

First, you’ll need to set up a checkprinting API. The server will send requests using HTTPS POST, and results are then formatted in XML. To get started, you’ll need an API Key and a Client ID. These will be your user account parameters. First:

  • Log into your account.
  • Select the “Account” page.
  • Select “API Access” at the top right of the screen.
  • View your API Key and Client ID. (Make sure you keep these secure and confidential.)

The system will let you know if the process was successful. Once you safely access the API system, it will perform an HTTP GET request for your chosen URL. After API access authentication, you can view your notification history status in real-time. 

Check Creation and Printing

When you make an order in the system, it will use a POST request with a JSON object. That JSON object will either be successful and process, or it will fail. If it fails, you may get an error identification code. 
Hopefully, you’ve keyed in the correct data in the following fields for processing. If so, you’ll see computer data with a long string of check identification code if all the input was successful. On the other hand, if the data was not successful or was deemed as corrupt, you may see an error code.

Processing Data 

Next, you can review your current checks to see their payment status. Payments may have the following codes:

  1. Released
  2. Processing
  3. Sent Out
  4. Cashed
  5. Cancelled
  6. Reissued

For mailed checks, you may see the following codes:

  1. USPS First Class Delivery
  2. USPS Priority Delivery
  3. FedEx or DHL One Day Delivery
  4. FedEx or DHL Two Day Delivery
  5. USPS Overnight Services

Next, you’re ready to perform live actions in the system. For example, if you would like to add a new bank account, you would select “Bank Accounts: add.” You would then view your Client ID and API Key first underneath the initial parameters. Afterward, you would complete some of the following fields:

  • Name on check
  • Address on check
  • Account number
  • Routing number
  • Bank name
  • Bank address
  • Currency
  • Signature threshold
  • Email address
  • Check number
  • Signature on file
  • ACH company ID
  • Purchasing order
  • Return

Now, for online check payment, you may see the following fields:

  • Payee
  • Amount
  • Address
  • Name
  • Memo
  • Notes
  • Reference
  • Pay
  • Payee email
  • Postage type
  • Transaction ID
  • Tax ID
  • Check number
  • Issue date
  • Bank account ID
  • Expedited request

You can also insert PDF files to be included in the following parameters:

  • Insert files
  • Insert print
  • Print using black and white
  • Print using black and white duplex
  • Print using color
  • Print using color duplex

When you’ve submitted your check for printing and processing, you can quickly obtain your check’s whereabouts when you set up a checkprinting API and properly use a GET request. You’ll be able to see if the server has received your check as well as its status in the system (like if the system has printed the check). Finally, you’ll be able to determine if an agent has prepared the check. 
The system with an agent would put your check in an envelope and stamp it for pick up by your preferred postal service agency. This makes online check payment processing and payroll outsourcing as seamless as possible. Professional check-printing and check-mailing services can revolutionize your business.
