Hosted payment simulators your CI can call
Host, HSM, POS, card, acquirer and issuer simulators. Hosted, scriptable and ready for CI—so you can test the whole transaction chain.

Host, HSM, POS, card, acquirer and issuer
Exercise each component on its own, then connect the pieces for end-to-end payment testing.
Host Simulator01
Model authorization endpoints with custom responses, timeouts and unsolicited messages.
HSM Simulator02
Test payShield-style commands, PIN operations and key management without a physical HSM.
POS Simulator03
Run terminal-side sales, reversals and settlement flows through manual or scripted execution.
APDU / Card Simulator04
Explore chip-card exchanges, from ATR and application selection through GENERATE AC.
Acquirer Host05
The Host Simulator in acquirer mode: acquiring host behavior and scheme-oriented transaction flows for issuer-side testing.
Issuer System06
Configure authorization decisions, approval rules and response codes for predictable scenarios.
Scripted from a pipeline,

HSMIllustrative flow and message fields only. This preview makes no network requests.
CLI & scripting
Drive repeatable simulator runs from command-line workflows and CI pipelines.
Scenario engine
Compose multi-step flows and verify the fields that matter at each stage.
Real-time debugging
Inspect formatted messages alongside raw hexadecimal data as they cross the wire.
Mock data generation
Use synthetic card, track, amount and EMV data to exercise different test conditions.
Load testing
Exercise sustained transaction volumes to expose connection, pool and timeout issues.
API testing
Test REST integrations alongside ISO 8583 flows across modern and legacy systems.
No terminal on your desk, no slot in the lab queue
Run the full transaction chain against hosted simulators instead of waiting for hardware or a shared test lab.
01
Rapid test setup
Start from hosted endpoints and prepared scenarios, without procuring physical test equipment.
02
Automated regression
Connect simulator runs to CI so repeatable payment checks become part of every build.
03
Developer-friendly APIs
Use documented provisioning and control interfaces within your existing testing workflow.
04
Performance visibility
Observe throughput and response timing under realistic host behavior and transaction loads.
05
Isolated test environments
Exercise your integration with synthetic data in test environments separate from production rails.
06
Hard-to-reproduce cases
Introduce timeouts, partial responses and malformed fields before those failures reach production.
Hosted simulation, answered
Endpoints, CI, data and what runs where.
The same simulators ship in the desktop Studio and as hosted endpoints. Locally they run on your machine for development; hosted, they give pipelines and distributed teams a stable URL instead of an environment per branch.
Yes. Provisioning and control interfaces are documented, and simulator runs can be scripted from command-line workflows, so repeatable payment checks become part of every build.
Host, HSM, POS, APDU / card, acquirer and issuer — exercised individually or connected for an end-to-end chain from terminal to authorization decision.
No. Hosted environments run on synthetic card, track, amount and EMV data, isolated from production rails.
That is the point of a simulator. Custom responses, response-window expiry, partial responses and malformed fields are all configurable, so those branches get exercised before production does.
Hosted endpoints come with Pro. Tell us the simulators and the volume you need and we will provision the environment; the desktop Studio stays free and open source under the GNU AGPL v3.
