Empty until a proof has been started. properties: host: type: string example: didit-tr-verify.example.com value: type: string TravelRuleSettingsDetail: type: object properties: is_enabled: type: boolean description: >- Whether the managed Travel Rule negotiation flow is active for outbound `travelRule` transactions on this application. jurisdiction: type: string maxLength: 8 description: >- Your VASP's operating jurisdiction code. Default `"EU"`. Didit maps it to the regime it stamps on your Travel Rule transactions as `travel_rule_regime` (for example `EU` or an EU member code becomes `eu`), which transaction rules can key on. Other Didit customers see it as your jurisdiction in the VASP directory once the Didit network lists your profile. name_matching_strictness: type: string enum: - NONE - STRICT - CONTAINS - DEFAULT - FUZZY description: >- How strictly beneficiary names must match before a transfer can reach COMPLETED. `CONTAINS` accepts one name whose words all appear in the other. confirmation_timeout_hours: type: integer minimum: 1 description: >- Hours an AWAITING_COUNTERPARTY transfer may remain unconfirmed before the periodic sweeper expires it. Default 48. timeout_outcome: type: string enum: - HOLD - REJECT - PROCEED description: >- What happens to the underlying transaction when a transfer expires. Default HOLD. sunrise_policy and non_responsive_policy take precedence when they apply and are set. threshold_amount: type: string description: >- Decimal string, in your application's default currency. Minimum transfer amount that triggers a managed exchange; transfers below it resolve straight to NOT_APPLICABLE. Didit compares the transaction amount converted to your default currency, or the `amount_in_default_currency` you send; when no converted amount is available, the threshold does not apply. Defaults to "0.00" (EU TFR applies no minimum amount). ownership_validation_mode: type: string enum: - FULL - SIMPLIFIED - AUTOMATED description: >- How much proof a wallet's ownership takes. `FULL` always needs a proof (signed message, test deposit or reviewed screenshot), never the end user's word. `SIMPLIFIED` accepts a self-declaration below `simplified_validation_threshold` and a proof above it. `AUTOMATED` lets the address book and earlier proofs answer on their own, self-declarations included while `allow_self_declaration` is true. Default `AUTOMATED`. simplified_validation_threshold: type: string description: >- Decimal string, default "0.00". In `SIMPLIFIED` mode a transfer below this amount (in the threshold currency) accepts a self-declaration. A transfer with no amount in that currency counts as above it. data_sharing_fields: $ref: '#/components/schemas/TravelRuleDataSharingFields' matching_rules: $ref: '#/components/schemas/TravelRuleMatchingRules' legal_name: type: string description: >- Your VASP's legal name. Required (non-blank) to set is_enabled to true. lei: type: string description: Your Legal Entity Identifier, surfaced in the VASP directory. compliance_email: type: string format: email description: >- Compliance contact email for your VASP profile. The Didit network lists your profile only once this address is confirmed through an emailed link (POST /v3/travel-rule/settings/compliance-email/confirmation/); changing it needs a new confirmation. is_discoverable: type: boolean description: >- Whether your VASP profile can be listed in the Didit network: found in GET /v3/travel-rule/vasps/ by other Didit customers and reached on the INTERNAL rail. Listing also needs a live application, Travel Rule on, a legal name and a confirmed compliance email; didit_network says which are missing. Default true. inbound_auto_accept: type: boolean description: >- When true, an inbound TRP inquiry whose beneficiary wallet is a verified address-book entry with a matching name is approved automatically. When false, that inquiry waits in ON_HOLD for you to approve or deny it with the ownership endpoint. INTERNAL-rail and after-deposit transfers are not affected. Default true. allow_self_declaration: type: boolean description: >- When true, the wallet-ownership widget offers self-declaration as a fallback proof method. Default true. allow_screenshot_proof: type: boolean description: >- When true, the wallet-ownership widget offers screenshot upload as an ownership evidence method. Default true. auto_wallet_verification: type: boolean description: >- When true, submitting an outbound Travel Rule transfer that needs end-user proof of wallet control auto-mints a wallet-ownership widget session bound to the transaction and exposes it in the transaction's action_required block. Default true. vasp_attribution_enabled: type: boolean description: >- When true, an outbound Travel Rule transfer that no rail can route is attributed through blockchain analytics: the destination wallet is resolved to its owning VASP, the entity is recorded on the transfer and in the VASP directory, and the rails are re-run once with the attributed name. Default true. counterparty_screening_enabled: type: boolean description: >- Opt-in sanctions and adverse-media screening of counterparty VASPs, billed per screening at the Company AML Screening price. When on, Didit screens the counterparty an outbound exchange reaches (reusing a screening younger than 30 days) and you can screen one with POST /v3/travel-rule/vasps/{vasp_id}/screening/. Default false: nothing is screened or billed. sunrise_policy: type: string enum: - '' - HOLD - REJECT - PROCEED description: >- What an expired transfer does to its transaction when the counterparty is a directory entry in a jurisdiction on sunrise_jurisdictions, which does not enforce the Travel Rule yet: HOLD moves it to review, REJECT declines it, PROCEED leaves its status untouched. Empty (the default) follows timeout_outcome. Applies before non_responsive_policy. sunrise_jurisdictions: type: array items: type: string readOnly: true description: >- Read-only. The countries (ISO 3166 alpha-2) Didit treats as in a Travel Rule sunrise period, where sunrise_policy applies. Currently CO, KH and VN. Any other jurisdiction, and an empty or unknown one, follows timeout_outcome. non_responsive_policy: type: string enum: - '' - HOLD - REJECT - PROCEED description: >- What an expired transfer does to its transaction when the counterparty is a directory entry whose responsiveness is UNRESPONSIVE: HOLD, REJECT or PROCEED, as for timeout_outcome. Empty (the default) follows timeout_outcome. sunrise_policy applies first when both fit. travel_address: type: string description: >- Read-only. Your VASP's own travel address - the encoded inbound TRP inquiry endpoint other VASPs use to reach you. Empty while `is_enabled` is false. disabled_networks: type: array items: type: string enum: - GTR - TRUST - VERIFYVASP - SYGNA description: >- Networks opted out of platform membership.

TravelRuleDataSharingFields: type: object description: >- The fields Didit sends to the counterparty VASP about your own users, per entity type. The `name` and the `wallet_address` are always sent, whatever the list says. An entity type you never chose shares every field.

The primary key has full access. A named key can be scoped: none, read or write per resource, limited to some workflows or to approved sessions, to a list of IP addresses, and to an expiry date. 401 means the key is missing, wrong, revoked or expired; 403 means the key has no access to this resource or action, or the request came from an address outside its IP list; 404 on a session route means the session is outside the key's workflows or statuses. A key without media access receives image, video and PDF URLs as null, and a key without sessions write receives session links and tokens as null.
