Customers API Overview

The Customers API and KYC Links API allow you to register your end users with Bridge, enabling seamless and compliant movement of stablecoins or fiat between your users’ wallets or bank accounts. Bridge handles all KYC (Know Your Customer) and KYB (Know Your Business) verification steps, so you have confidence that your users meet all applicable compliance requirements.

​
Key Concepts

  • Customers: Represent end users of your platform.
  • KYC/KYB: Mandatory identity and business verification handled by Bridge.
  • Endorsements: Used to verify if a customer is eligible to transact on specific rails or services.

​
Customer Registration

To register a new customer, use either the Customers API or the KYC Links API. Upon registration:
  • Customers must agree to Bridge’s Terms of Service.
  • You must provide basic identity information such as:
    • Full name
    • Email address
    • Government-issued identifiers (e.g., SSN for individuals, EIN/TIN for businesses)
Bridge will validate this information to approve the customer for transactions. If additional information is needed, Bridge will return precise requirements for completion of the KYC/KYB process. 📘 See Also: KYC Requirements for a detailed list of required fields and document types.

​
Accepting Terms of Service Without KYC

In cases where you only need users to accept Bridge’s Terms of Service without initiating KYC/KYB, use the Terms of Service API. This is useful for scenarios where full onboarding isn’t immediately required but legal acceptance of terms is necessary.

​
Checking Customer Eligibility (Endorsements)

Use Endorsements to verify whether a specific customer is eligible to interact with a particular service, rail, or transaction type. This step ensures the customer has passed all necessary checks before you attempt transfers, deposits, or withdrawals via Bridge.
