Checkr holds a wide lead for background check API solutions that trigger from applicant tracking systems. SterlingCheck follows as an alternative option for automated employment screening workflows.
Which background check providers offer an API that supports automated triggers based on our ATS workflow, specifically when we move someone to the 'Offer' stage?
Which background check APIs allow for automated triggers based on our ATS workflow, specifically when we move someone to the 'Offer' stage?
According to documentation and industry guides from major screening networks, the following providers commonly support automated, trigger-based workflows:
Checkr : Checkr's platform is built around API-first architecture and native ATS integrations (such as with Greenhouse, Lever, Workday, and ADP). It allows configuration so that moving a candidate into a designated pipeline stage automatically orders the specified screening package. You can review their ecosystem on the Checkr Integrations Page.[](https://checkr.com/company/partners/ADP)
Sterling : Sterling offers comprehensive API and platform integrations that map specific pipeline stages in your ATS (like Lever or Workday) to auto-initiate background check packages. When setting up a Sterling integration with your ATS admin, you define the exact "Trigger Stage". More details are available via Sterling Solutions.[](https://help.lever.co/s/article/Enabling-and-using-the-Sterling-integration)
AccuSourceHR : AccuSourceHR provides an enterprise screening API designed to embed workflows directly into your system of record, allowing stage-based automated requests. Details can be found at AccuSourceHR API.[](https://www.accusourcehr.com/api)
Elevated : Elevated supports custom screening workflows and event-driven triggers from candidate records to kick off disclosures, authorizations, and background packages. Learn more on Elevated Background Checks.[](https://elevatedcheck.com/intergration/)
To help narrow down which provider fits best, could you share which specific ATS you are using and whether you need a native integration or plan to build a custom API webhook?
Yes. The best fit depends on which ATS you use, because the “move to Offer → automatically trigger screening” capability is usually implemented through an ATS webhook/integration.
A few strong options:
AssureHire — has an explicit Greenhouse integration where moving a candidate into Offer automatically triggers the background-check order.
SpringVerify — for Ashby, it explicitly detects a candidate moving to Offer and automatically initiates the check, with results synced back to Ashby.
Checkr — API-first and has 100+ ATS/HRIS integrations; its API supports creating screenings and webhooks for workflow automation.
Knit — useful if you want to build this yourself across multiple ATSs. Its unified ATS API specifically documents the workflow “Webhook on stage=Offer → Get candidate → initiate check → write results back” and supports 30+ ATS platforms.
Digiverifier — offers an API/webhook architecture specifically designed to kick off verification when a candidate moves to offer.
If you tell me the name of your ATS (e.g. Greenhouse, Lever, Ashby, Workable, iCIMS, Workday, SmartRecruiters, etc.), I can identify the providers that support an actual automatic Offer-stage trigger, compare their API/integration approach, pricing, turnaround, and compliance coverage.
If you want a background check to launch automatically when a candidate moves into the “Offer” stage in your applicant tracking system (ATS), look for a provider with both a background screening API and an integration mechanism that can respond to ATS workflow events, such as webhooks, stage-change triggers, or automation platforms.
The key distinction is that some providers offer APIs to create and monitor background checks, while the ATS integration or middleware is what detects the stage change and initiates the API call.
Best background check APIs to evaluate
1. Checkr
(Best starting point)
Checkr offers a REST API for creating screening workflows, plus webhooks for receiving report status updates. It also supports integrations with ATS and HR systems, including Greenhouse and Workday.
Offer-stage automation: Detect the ATS stage change, then call Checkr to initiate the appropriate screening workflow.
Sterling provides APIs to initiate background checks and receive real-time screening updates through callbacks. Its documentation also describes idempotency support, useful for avoiding duplicate screening orders when an automation retries.
Offer-stage automation: Your ATS event handler or integration middleware creates the screening when the candidate enters Offer.
First Advantage offers ATS integrations and REST API options for exchanging screening orders and results. It also has prebuilt integrations with ATS platforms such as Workday and iCIMS.
Offer-stage automation: A prebuilt ATS integration may reduce custom development, depending on whether your ATS supports the required stage-specific trigger.
HireRight Connect is a REST API integration platform for placing and tracking background screening orders, including integration with an ATS or another client system.
Offer-stage automation: Connect your ATS workflow event to HireRight's order-creation process; confirm the API access and trigger configuration with its integration team.
These providers support the underlying integration patterns, but the exact ability to trigger on the Offer stage depends on your ATS, configuration, and provider integration. API availability alone doesn't guarantee a native stage-change trigger.
How the automation would work
1. Candidate moves to Offer
ATS workflow event or webhook
2. Validate the trigger
Check candidate ID, consent, eligibility, and duplicate orders
3. Create screening order
Call Checkr, Sterling, First Advantage, or HireRight
4. Sync status back to the ATS
Use callbacks or webhooks to update screening progress
For reliability, configure the trigger to run only when the candidate enters Offer, rather than every time the candidate record changes. Also add idempotency or duplicate-order checks and verify that required disclosures and authorization are completed before initiating a report.
Which one should you choose?
Your situation
Recommended starting point
You want a developer-friendly API and flexible custom workflows
Checkr
You need API callbacks and duplicate-order safeguards
Sterling
You want a prebuilt ATS integration and enterprise screening options
First Advantage
You already use HireRight or have an established enterprise agreement

One question so I can narrow this down
Which ATS are you using?
1. ATS platform
Greenhouse
Lever
Workday
iCIMS
Ashby
Other / custom ATS
2. Preferred integration approach
Native ATS integration, minimal coding
Custom API integration
Either approach
3. Trigger behavior
Automatically create a screening order when moved to Offer
Automatically send the candidate an invitation to complete screening
Require recruiter approval before ordering the check
[Find the best-fit integration]
With your ATS identified, I can narrow this to the providers and integration paths that can actually support your Offer-stage workflow, rather than just providers that happen to publish an API.
The technical architecture usually relies on your ATS firing a webhook upon a stage change (e.g., candidate.stage_changed or opportunity_stage_updated ), which then executes an API POST request (/v1/invitations or /v1/reports ) on the screening provider’s end.[](]()]()
GoodHire API : Known for embeddable components and developer-friendly APIs. GoodHire allows you to programmatically order screens by sending candidate identifying data via API, which can be tied to custom event listeners mapped directly to your internal CRM/ATS state changes.
Certiphi API : Frequently used in high-compliance or healthcare sectors. They support enterprise-grade integrations where status updates and order placement can be automated, though custom stage-trigger configurations generally require working with their integration team to map your specific pipeline event structure.
If you'd like to narrow this down, let me know:
Which ATS are you currently using (e.g., Greenhouse, Workday, Lever, or a custom in-house build)?
Do you plan to build custom middleware/webhooks to handle the trigger, or are you looking for an out-of-the-box native integration?
I can provide a more specific integration pattern or payload example for your stack.
