Get Ramp Intent

Retrieve the full details of a ramp intent, including the generated widget URL for embedding. This endpoint also manages automatic status transitions — the intent moves from created to active on the first GET request, and auto-expires if past its expiresAt timestamp.

Response Fields

Intent Object

Parameter	Type	Description
intentId OPTIONAL	string	Unique intent identifier
type OPTIONAL	string	buy or sell
fiatCurrency OPTIONAL	string	Fiat currency code
cryptoCurrency OPTIONAL	string| null	Crypto identifier
amount OPTIONAL	number| null	Default amount
status OPTIONAL	string	Lifecycle state: created, active, completed, expired, or cancelled
kycStatus OPTIONAL	string	KYC sub-state: pending, in_review, approved, declined, or expired. When KYC is declined, status flips to cancelled and cancelReason='kyc_rejected'.
cancelReason OPTIONAL	string| null	Reason the intent was cancelled. kyc_rejected when KYC was declined; kyc_expired for KYC session expiry. null otherwise.
successUrl OPTIONAL	string| null	Merchant success redirect URL
cancelUrl OPTIONAL	string| null	Merchant cancel redirect URL
expiresAt OPTIONAL	string	Expiry timestamp
metadata OPTIONAL	object	Custom metadata
wallets OPTIONAL	array	Array of { network, address } wallet objects
userId OPTIONAL	string	Merchant's user identifier (KYC record key)
kycVerified OPTIONAL	boolean	Whether KYC was pre-verified by merchant. Convenience flag — equivalent to kycStatus === 'approved'.
customerEmail OPTIONAL	string| null	Customer email if provided

Root Fields

Parameter	Type	Description
widgetUrl OPTIONAL	string| null	Signed widget URL for iframe embedding. null if expired.
kycRequired OPTIONAL	boolean| undefined	Whether ZenPays KYC verification is required. Present when kycVerified is false and the user has not yet been verified.
kycVerificationUrl OPTIONAL	string| null	URL to redirect user for identity verification. null if no verification session has been initiated yet.

KYC Gating

The response shape depends on the user's KYC status:

Scenario 1: KYC pre-verified by merchant (kycVerified: true on the intent)

Widget URL is returned immediately. No KYC prompts.

Scenario 2: KYC verified via ZenPays (kycVerified: false, user already verified)

Widget URL is returned. kycRequired is absent or false.

Scenario 3: KYC required (kycVerified: false, user not verified)

widgetUrl is null, kycRequired is true. If a verification session exists, kycVerificationUrl contains the URL. If not, call initiateKyc (or the equivalent REST endpoint) to create a session.
