For Agents
Create and manage marketplace account holders, sub-accounts, bank accounts, and shareholders on Adyen's classic platform integration. Handles KYC verification and document uploads for marketplace onboarding.
Use for: I need to onboard a new marketplace seller on Adyen, Create a sub-account for an existing account holder, Check whether KYC verification has passed for an account holder, Upload an identity document for seller verification
Not supported: Does not handle payment processing, checkout flows, or terminal management — use for marketplace account onboarding and management only.
Onboard and manage marketplace account holders, sub-accounts, and their associated bank accounts and shareholders on the Adyen for Platforms classic integration. The API handles the full account lifecycle from creation through KYC verification, document upload, and suspension or closure. Each account holder can contain multiple accounts with separate balances and payout configurations.
Install Jentic One Beta
Connect the Account API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Account API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
Capabilities
What an agent can do with Account API.

Use Cases
Patterns agents use Account API for, with concrete tasks.
★ AI Agent Marketplace Onboarding
AI agents automate marketplace seller onboarding through Jentic by creating account holders, attaching bank accounts, and uploading verification documents without directly managing Adyen API keys. An agent searches for 'create an account holder' via Jentic, receives the operation schema with required legal entity fields, and executes the call. Subsequent verification document uploads and status checks follow the same pattern.
Search Jentic for 'create Adyen account holder', load the schema, create an account holder with business details and legal entity type, then upload an identity document via /uploadDocument
Marketplace Seller Onboarding
Onboard new sellers on a marketplace platform by creating account holders with business registration details, attaching bank accounts for payouts, and initiating KYC verification. The API supports individual and business entity types with fields for shareholders, UBO declarations, and legal arrangements. Verification runs automatically after document upload and returns status via the /getAccountHolder endpoint.
Create an account holder with legalEntity type Business, add a bank account via the accountHolder payload, then call /checkAccountHolder to initiate KYC verification
KYC Document Management
Upload and manage identity verification documents required for regulatory compliance across different jurisdictions. The uploadDocument endpoint accepts base64-encoded files (passport, driving license, bank statement) and associates them with specific account holders or shareholders. Document verification status is returned in the account holder details response.
Upload a base64-encoded passport image for an account holder using POST /uploadDocument with documentType PASSPORT, then retrieve the account holder to check verification status
Account Lifecycle Management
Manage the full lifecycle of marketplace accounts from active trading through suspension, reactivation, and eventual closure. The API provides separate endpoints for suspending account holders (freezing payouts and trading), unsuspending them after compliance resolution, and permanently closing accounts with final balance settlement.
Suspend an account holder using POST /suspendAccountHolder with the accountHolderCode, verify suspension status, then reactivate with POST /unSuspendAccountHolder

Why Jentic?
Three things that make agents converge on Jentic-routed access.
Credential isolation
Adyen X-API-Key credentials are stored encrypted in the Jentic MAXsystem vault. Agents authenticate with scoped tokens — the raw API key never enters the agent's context or logs.
Intent-based discovery
Agents search by intent (e.g., 'onboard a marketplace seller' or 'upload verification document') and Jentic returns the matching Account API operation with its full request schema including required legal entity fields.
Time to first call
Direct Adyen Account API integration: 3-7 days for auth, account holder creation, document upload flow, and webhook setup. Through Jentic: under 1 hour — search, load schema, execute with credential isolation.

FAQs
Specific to using Account API through Jentic.
What authentication does the Adyen Account API use?
The Adyen Account API accepts an API key via the X-API-Key header or HTTP Basic authentication with your web service user credentials (ws@MarketPlace.YOUR_PLATFORM_ACCOUNT as username). Through Jentic, your Adyen API key is stored encrypted in the MAXsystem vault and agents receive scoped access without seeing the raw key.
Can I create account holders for both individuals and businesses?
Yes. The POST /createAccountHolder endpoint accepts a legalEntity field with type Individual or Business. Individual entities require personal details (name, date of birth, address). Business entities additionally require registration number, shareholders, and UBO declarations. Verification requirements differ by entity type and jurisdiction.
What are the rate limits for the Adyen Account API?
Adyen applies per-endpoint rate limits based on your contract tier, typically 30-60 requests per second for account management operations. The /uploadDocument endpoint has lower limits due to payload size. If exceeded, the API returns HTTP 429. Contact your Adyen account manager for limit increases on high-volume onboarding flows.
How do I upload KYC documents through the Adyen Account API via Jentic?
Search Jentic for 'upload verification document' to find the POST /uploadDocument operation. Required fields are accountHolderCode, documentDetail (with documentType such as PASSPORT or BANK_STATEMENT), and the base64-encoded file content. Jentic loads the full schema including supported document types. Sign up at https://app.jentic.com/sign-up to get started.
What verification document types does the Account API accept?
The /uploadDocument endpoint accepts PASSPORT, DRIVING_LICENCE, ID_CARD, BANK_STATEMENT, INCORPORATION_CERTIFICATE, and COMPANY_REGISTRATION_SCREENING. Documents must be base64-encoded and under 10MB. The response confirms upload status and the /getAccountHolder response shows which verification checks are pending or complete.
Is the Account API part of the Adyen classic or new integration?
The Account API (v6) is part of Adyen's classic integration for platforms. New implementations should consider the Adyen Balance Platform APIs instead, which provide a more modern architecture. The classic Account API remains fully supported for existing integrations and handles account holders, sub-accounts, bank accounts, and KYC flows.
