Paper Checks

Documentation | Checkbook


In our increasingly digital world, paper checks still account for over 25% of non-cash payments. And while we are a digital-first company, we still support paper checks for our clients needing it. Paper check features include:

  • Mailed Same Day (if request is made before 1:00PM PST)
  • USPS Tracking Details
  • FedEx Overnight Mail
  • Optional PDF Insert


Verified Bank Account Needed

In order to be able to send checks, you need to have a verified bank account in our system. Please refer to the Add a Bank Account section for instructions about adding a bank account to your profile.

API Basic

The API reference for sending a Paper Check can be found here. The interactive form allows you to test the API endpoint in our demo environment right from the reference page.

The previous request is for the demo environment. You will need to use either the sandbox endpoint if you want to send test checks, or the production endpoint if you want to send real checks.
