Step 1: Set your API key
All requests require thex-api-key header. Use sk_test_* keys during development.
Sandbox keys (
sk_test_*) create real data but Metro 2 files never reach bureaus. Use them freely during development.Step 2: Create a consumer
Register the individual whose payments you’ll report.Response (201)
The SSN is encrypted at rest and never returned in any API response. Save the
id for creating tradelines.Step 3: Create a tradeline
A tradeline represents an ongoing payment obligation being reported to credit bureaus.Response (201)
Step 4: Report a payment
Each month, report payments against the tradeline. The API automatically updates the tradeline’s status, balance, and payment history.Response (201)
tradeline_status shows the auto-updated fields. The payment_history value "0" means “current” for this month.
