[Stablecoin Account API Publisher Disclaimer](/stablecoin-account/v1.6/guide/stablecoin-account-api-publisher-disclaimer) The FATF Travel Rule requires identifying the counterparty of a crypto transfer in certain cases. In the Stablecoin Account API, that information travels in one object — `meta_data` — used in three places: * [Create Address Book](/stablecoin-account/v1.6/api-reference/create-address-book) and [Update Address Book](/stablecoin-account/v1.6/api-reference/update-address-book) — describing the **beneficiary** of a withdrawal destination. * [Submit Deposit Sender Travel Rule](/stablecoin-account/v1.6/api-reference/create-deposit-sender) — describing the **originator** of an incoming deposit. ## When `meta_data` is required `meta_data` is optional at the API level, but must be provided (and pass validation) when any of these apply: | Scenario | Why | | ------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------- | | The address belongs to a third party (`address_party: third_party`) | Beneficiary identity is required | | The wallet is hosted by an exchange (`wallet_type: hosted`) | The custodian VASP must be identified | | The address is a Binance-routed withdrawal destination | The withdrawal is rejected until the address book entry carries Travel Rule data (error: `missing travel_rule_data for binance withdraw`) | | A deposit arrives with `need_travel_rule: true` | The deposit is held until originator data is submitted | Once you provide `meta_data`, its fields are validated — a provided-but-invalid object fails the request. ## Field reference Top level — both fields are required whenever `meta_data` is present: | Field | Type | Values | Description | | ------------------------- | ------ | ---------------------------- | ------------------------------------------------------------------------------------------------------------------ | | `wallet_type` | string | `hosted`, `unhosted` | `hosted` for a custodial/exchange wallet (requires VASP details); `unhosted` for a self-custody wallet | | `address_party` | string | `first_party`, `third_party` | `first_party` when the address belongs to the account holder; `third_party` when it belongs to another beneficiary | | `beneficiary_information` | object | — | Required when `address_party` is `third_party` or `wallet_type` is `hosted` | Inside `beneficiary_information`, requirements depend on the entity and wallet type: | Field | Required when | Description | | ------------------------- | ------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------- | | `entity_type` | Third party | `individual` or `corporation` | | `first_name`, `last_name` | Third party and `entity_type: individual` | Beneficiary given and family name | | `company_name` | Third party and `entity_type: corporation` | Beneficiary company name | | `country` | Third party | ISO 3166-1 alpha-2, lowercase — use a `countryCode` from [List Countries](/stablecoin-account/v1.6/api-reference/list-countries) | | `city` | Third party | Use a `regionName` from [List Regions](/stablecoin-account/v1.6/api-reference/list-regions) | | `vasp_id` | Hosted wallet (at least one of `vasp_id` / `vasp_name`) | Use an `identifier` from [List VASPs](/stablecoin-account/v1.6/api-reference/list-vasps) | | `vasp_name` | Hosted wallet | The VASP's name. If the exchange is not in the VASP list, put its name here and omit `vasp_id` | | `id_type`, `id_primary` | Optional | Beneficiary identity document type and number | Typical validation errors: `invalid wallet_type`, `invalid address_party`, `invalid entity_type`, `individual third party requires first_name and last_name`, `corporation third party requires company_name`, `third party requires country and city`, `hosted wallet requires vasp_id or vasp_name`. ## Examples An individual third-party beneficiary at an exchange (hosted): ```json theme={null} { "wallet_type": "hosted", "address_party": "third_party", "beneficiary_information": { "entity_type": "individual", "first_name": "John", "last_name": "Doe", "country": "sg", "city": "Singapore", "vasp_id": "I1QNLP", "vasp_name": "Binance" } } ``` A corporate third party using a self-custody wallet (unhosted): ```json theme={null} { "wallet_type": "unhosted", "address_party": "third_party", "beneficiary_information": { "entity_type": "corporation", "company_name": "Acme Pte Ltd", "country": "sg", "city": "Singapore" } } ``` The account holder's own self-custody wallet — beneficiary information can be omitted: ```json theme={null} { "wallet_type": "unhosted", "address_party": "first_party" } ``` ## Look up reference data Three read-only endpoints supply the values that `beneficiary_information` fields must come from: ### List VASPs [List VASPs](/stablecoin-account/v1.6/api-reference/list-vasps) returns the directory of Virtual Asset Service Providers. Search with `q` (matches `vaspName` and `identifier`) and cap results with `limit`. Use the `identifier` value as `vasp_id`. ```bash theme={null} curl "https://api-sandbox.uqpaytech.com/api/v1/ramp/wallet_address/vasps?q=binance&limit=10" \ -H "x-auth-token: YOUR_API_TOKEN" ``` ### List countries [List Countries](/stablecoin-account/v1.6/api-reference/list-countries) returns only currently selectable countries as `countryCode` (ISO alpha-2, lowercase) and `countryName` pairs. Use `countryCode` as `country`. ### List regions [List Regions](/stablecoin-account/v1.6/api-reference/list-regions) takes a required `country` code and returns that country's regions; use a `regionName` as `city`. Countries without regions return an empty array. ## Related * [Address book](/stablecoin-account/v1.6/guide/address-book) — where withdrawal-side `meta_data` lives * [Travel Rule for deposits](/stablecoin-account/v1.6/guide/travel-rule-for-deposits) — the originator-side flow * [Send withdrawals](/stablecoin-account/v1.6/guide/send-withdrawals) * [List VASPs API](/stablecoin-account/v1.6/api-reference/list-vasps)
