Install Jentic One Beta

Connect the Adyen Test Cards API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Adyen Test Cards 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 | sh

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 instance

Jentic 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 Adyen Test Cards API.

Generate one or more custom test card ranges via POST /createTestCardRanges with brand, issuerCountry, and outcome

Cover specific 3D Secure 1 and 3DS2 outcomes for QA — Authorised, ChallengeShopper, IdentifyShopper, Refused

Simulate fundingSource (credit, debit, prepaid) and issuer country combinations not present in the standard test deck

For Agents

Generate custom Adyen test card number ranges for QA scenarios that the standard test cards do not cover.

Use for: Generate a custom test card that triggers a 3DS2 challenge, Create a test card range for an issuer in a specific country, Simulate a refused authorisation for QA testing, Find or create a debit-card test PAN for a regression suite

Not supported: Does not authorise live payments, generate real card credentials, or simulate end-to-end checkouts — use only for generating custom Adyen test card PAN ranges for QA scenarios.

Use Cases

Patterns agents use Adyen Test Cards API for, with concrete tasks.

★ QA Regression Coverage for Edge Cases

Standard Adyen test cards cover the main happy paths. To reproduce a specific issuer country, fundingSource, or 3DS2 outcome, QA teams call POST /createTestCardRanges with the desired brand, issuerCountry, and resultCode, and receive a fresh PAN range. The new PANs are then used in regression suites to exercise that exact path against Adyen's test endpoint, ensuring future code changes do not regress the handling of that case.

Call POST /createTestCardRanges with brand=visa, issuerCountry=NL, fundingSource=debit, and the desired authorisationResultCode for the QA scenario

Developer Sandbox Setup

When a new developer joins the team, they need a deterministic set of test cards to exercise the integration in their local sandbox. POST /createTestCardRanges produces a deck tailored to the team's coverage matrix: one card per brand, one card per fundingSource, one card for every refusal reason the integration handles. The same call can be re-run any time to refresh the deck after Adyen's test environment is rotated.

Call POST /createTestCardRanges once per scenario in the team coverage matrix and store the resulting PANs in the team's secrets manager for use in sandbox runs

Refusal-Reason Simulation

Integrations need to handle every refusal reason Adyen can return — fraud block, expired card, do-not-honour, declined, suspected fraud, and more. POST /createTestCardRanges generates a card range for each refusal scenario by setting the appropriate refusalReason on the request. Tests then call POST /authorise on the Payment API or POST /payments on Checkout with the generated PAN to confirm the integration handles each refusal cleanly.

Call POST /createTestCardRanges with refusalReason=FRAUD to obtain a PAN that always returns Refused with a fraud reason, then exercise the full refusal-handling path

AI Agent Test Data Provisioning via Jentic

An automated test orchestration agent that prepares ephemeral test data per CI run searches Jentic for 'create Adyen custom test card range', loads the schema for /createTestCardRanges, and executes once per scenario in the test plan. Jentic injects X-API-Key from the encrypted vault and the resulting PANs are written to the CI run's secret store, never to disk.

Search Jentic for 'create Adyen custom test card range', load the createTestCardRanges schema, then execute once per scenario in the CI run's test plan

Key Endpoints

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Your Adyen X-API-Key and basic auth credentials are stored once, encrypted, by your own Jentic One instance and injected at execution time. They never enter the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'create a test card that returns a 3DS2 challenge', and Jentic returns the createTestCardRanges operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Adyen Test Cards API through Jentic.

What authentication does the Adyen Test Cards API use?

The API supports an API key in the X-API-Key header (ApiKeyAuth) and HTTP Basic auth (BasicAuth) using web-service user credentials, the same auth model as the rest of Adyen's classic-platform APIs. Through Jentic, the credential is held encrypted in the vault and only a scoped execution token is exposed to the agent.

What outcomes can I simulate with custom test cards?

POST /createTestCardRanges accepts parameters that set the brand, issuerCountry, fundingSource, authorisationResultCode, and refusalReason on the generated PAN range. This lets you generate test cards that always Approve, always Refuse with a specific reason, or trigger ChallengeShopper or IdentifyShopper for 3DS2 testing.

Can I use these test cards against the live Adyen environment?

No. Custom test card ranges generated by this API are valid only against Adyen's test endpoints, such as pal-test.adyen.com and checkout-test.adyen.com. They will not authorise on the live endpoints; the production environment uses real card credentials only.

How do I generate a custom test card with the Test Cards API through Jentic?

Search Jentic for 'create Adyen custom test card range', load the createTestCardRanges schema, then execute with brand, issuerCountry, fundingSource, and the desired authorisationResultCode. Jentic injects X-API-Key from the encrypted vault. Get an account at https://app.jentic.com/sign-up.

What are the rate limits for the Adyen Test Cards API?

Adyen does not publish a fixed numeric rate limit for the Test Cards API in the spec; usage is administrative and intended for occasional QA setup rather than per-transaction calls. If 429 responses appear, contact Adyen support to review the merchant account's quota.

How is this different from the standard Adyen test cards?

Adyen publishes a fixed list of standard test card PANs that cover the main approval and refusal paths. The Test Cards API generates custom ranges that fill specific gaps — a particular issuer country, a specific refusalReason, a 3DS2 step-up scenario — that the standard list does not include. Use it when the standard cards cannot reproduce a case your integration must handle.
