Sandbox Test Documents

Stables uses Sumsub to process identity verification. When testing KYC in the sandbox, use the test document templates below to simulate different verification outcomes.

How to testCopy Anchor Link

1. Confirm you're using a sandbox API key (sti_test_...) against https://api.sandbox.stables.money.
2. Reference one of the test documents below as the id_documents or proof-of-address payload when creating or updating a customer.
3. Observe the resulting verification_levels[].status and verification_levels[].sub_status on the customer record. The API returns lowercase statuses (approved, requires_action, rejected); the VERIFICATION_* names below are the forms sent in kyc_link.updated.status_transitioned webhooks.

• Sumsub's verification engine recognizes documents in a wide range of languages and character sets, so equivalent test templates for other supported countries behave the same way.
• Since business customers are not automatically approved in sandbox (see Setup a sandbox environment), these templates are most useful for exercising individual (KYC) verification-state transitions end-to-end.
• The downloadable sample image files themselves are hosted by Sumsub — see Sumsub's verification document templates page.
