Subdomain Finder API + GitHub Integration

Why connect them

The Subdomain Finder API in GitHub.

GitHub is where developers build software together. Connecting APIs to GitHub enables automated code workflows, intelligent issue management, and CI/CD enhancements. Supercharge your development processes with external data.

What you can build

Workflows worth wiring.

Automatically validate URLs in README files for broken links

Check DNS configurations when deploying to new environments

Verify SSL certificates as part of deployment pipelines

Create issues automatically when external monitoring detects problems

Templates

Ready-made ideas.

New issue created in GitHub Fetch subdomains for domain in issue → add host list, records, and count as issue comment

Subdomain Discovery in GitHub Issues

Enrich GitHub security issues with subdomain discovery data including hosts and IP records.

Scheduled weekly trigger Fetch subdomains → create GitHub issue with host list, totalFound, and rootDomain details

Automated Recon Report in GitHub

Generate weekly reconnaissance reports as GitHub issues with full subdomain discovery results.

Setup

Connect it in a few steps.

Set up with Zapier

1
Set the trigger. Create a Zap with GitHub as the trigger app and "New issue" as the event. Connect your account.
2
Add the API action. Add APIVerve as the action, select the Subdomain Finder API, and map your trigger data to the request.
3
Send it back. Add a second GitHub action for "Create issue" and map the returned fields (like rootDomain) into it.
4
Test & turn on. Test the Zap with real data to confirm the mapping, then turn it on.

Set up with Make

1
Add the trigger. Create a scenario and add a GitHub module set to "New issue". Authenticate your account.
2
Call the API. Add an HTTP module pointing at api.apiverve.com/v1/subdomainfinder with your x-api-key header. Pass the trigger's data as the input.
3
Parse & map. Add a JSON module to read the response, then a GitHub module for "Create issue". Map fields like data.rootDomain into place.
4
Activate. Run once to confirm the mapping, then switch the scenario on and set its schedule.

Set up with n8n

1
Add the trigger node. Start a workflow with a GitHub trigger node for "New issue" and connect your credentials.
2
Add an HTTP Request node. Point it at api.apiverve.com/v1/subdomainfinder using Header Auth (x-api-key). Feed in the trigger data.
3
Map with expressions. Add a GitHub node for "Create issue" and reference the response with expressions such as {{ $json.data.rootDomain }}.
4
Execute & activate. Execute manually to verify, then activate the workflow for production.
