Buyer evidence through the API
Choose the documented BlueCheck service suitable for the covered transaction.
Built around the decision that matters
Choose BlueCheck for buyer age evidence in a marketplace flow you control. Your application determines which seller, product and destination require a check, calls the suitable service and applies the outcome to the covered transaction. Seller eligibility remains a separate decision.
Why BlueCheck
Verification built around your business.
Your marketplace keeps control
Maintain the seller, product and destination policy in your own application.
A transaction-level decision
Associate the outcome with the relevant order reference and enforce it in your platform.
Verify the buyer where the transaction needs it
Bring your marketplace architecture and covered categories to BlueCheck. Review the suitable API service and the evidence your buyer must supply. Your platform can call the service for the relevant transaction while keeping unrelated purchases on their configured path.

Keep multi-seller order handling in your platform
A mixed basket can include several sellers and one covered item. Decide how orders split and where evidence is required, then connect the result to those references. BlueCheck supplies the documented verification service; your application owns routing and enforcement rather than relying on an unverified native marketplace connector.
Keep eligibility and age as separate decisions
Seller onboarding, licensing and product permissions do not establish buyer age, and an adult buyer does not authorize a seller or product. Maintain those controls alongside verification. Review changed sellers, order edits, partial failures and any proposed result reuse before release.
Questions about this approach
Does this replace seller onboarding?
This page focuses on buyer age verification. Seller identity, licensing and eligibility remain separate marketplace decisions.
Can one result cover every seller?
Discuss reuse and scope before sharing a result. Contracts, policy and the supported implementation determine what may be reused; universal portability is not assumed.
