Integration Resources
Guidance on connecting ONKORE with your platform through supported methods.
Which integration approach fits your business?
Start with your payment workflow. Availability and compatibility must be confirmed for your specific provider and platform.
Need online checkout?
Ask about hosted checkout or a compatible payment gateway for your website or application.
Need to collect remote payments?
Review payment links or a virtual terminal for invoices, phone orders, and other eligible use cases.
Need in-person acceptance?
Confirm terminal and POS compatibility before selecting hardware or beginning development.
Building a custom integration?
Contact ONKORE to verify available APIs, SDKs, credentials, testing access, and processor requirements.
Compatibility first: These resources describe possible integration methods, not a guarantee that every feature, API, SDK, or test environment is available for every merchant.

Integration FAQs
Integration FAQs
Does ONKORE offer a public API?
Developer resources are available for supported integrations. Contact ONKORE to discuss API availability and integration options. Where a public API is not yet available, ONKORE supports integrations through payment gateways, partner integrations, middleware, and migration services depending on your setup.
How do I integrate ONKORE with my platform?
Integration options depend on your gateway, processor, integration method, or supported third-party platform. ONKORE can connect through direct integrations, partner integrations, payment gateways, middleware, APIs, or migration services. Contact our integration team to confirm what is supported for your environment.
Is a sandbox environment available?
A sandbox or test environment may be available where supported by your integration method. Contact ONKORE to confirm whether sandbox access is available for your setup before going live.
Do you offer SDKs?
SDK availability depends on your integration method and supported platform. Where SDKs are not yet publicly available, ONKORE supports integrations through gateways, middleware, and APIs. Contact our integration team to discuss the options for your stack.
How do I reduce my PCI compliance scope?
Using a hosted checkout page, payment links, or tokenization where supported can reduce your PCI scope by keeping sensitive card data off your servers. ONKORE can advise on the integration method that best fits your compliance needs.
