A list of responses to frequently asked questions about the Certn API.

API Requests

Are there limits on how many requests I can send in a certain period of time?

Certn's API has a rate limit of:

  • 240 requests/minute (60s rolling window) and

  • 14,400 requests/day (24hr rolling window).


What is a quickscreen, and how do I use it?

A quickscreen allows you to run a check on an applicant without involving the applicant.

  • When running a quickscreen, add /quick to the URL.

  • The response you get from a quick screen is set to ANALYZING. To receive live results, setup a webhook, or make a subsequent call.

Pre-requisite: Obtain all the required information prior to running the check, and include it in your request.

Make sure to obtain the proof of consent from your applicant before running the quickscreen.

What is an invite, and how do I use it?

An invite allows you run a check on an applicant by inviting them to provide the required information and complete the appropriate consents via an email or SMS invite from Certn.

What is a manual review, and how does it work?

When filing an application with an Enhanced Identity Verification, applicants upload a selfie and pictures of their ID. If our tool cannot validate them, it flags the application for Manual Review.

A customer support agent from our team then reaches out to the applicant via the email on file and asks them to upload new photos. Once received, our agents re-process the application.
