How to choose
Which platforms does it need to support?
Choose a provider that supports the platforms where you plan to take payments. The category includes web and API options, as well as iOS and Android support.
Check the product details for platform coverage before choosing. Nuvei describes its service as payment infrastructure and offers processing for businesses.
How is the payment service priced?
Compare the stated pricing model and the fee that applies to your use. Listed pricing ranges from per-transaction starting amounts to monthly fees or pricing on request.
For example, Authorize.net lists pricing from $25 per month, while Dwolla says pricing is available on request. Confirm the provider's current terms before deciding.
Can I try it without paying?
Check whether the provider offers a free plan, and read what it includes before relying on it. Airwallex Payments and Mollie list free plans; a free plan is not the same as a free trial.
Does it offer an API?
An API lets one software service exchange information with another. If you need payment features to connect to your own software, check for API support and documentation depth.
The API mark indicates whether a public API is listed. It does not by itself tell you whether the API fits your needs.
Questions
What is a payment API?
A payment API is a way for software to exchange information with a payment service, so a business can accept or process payments through its software.
How do I choose a payment API?
Match platform support to where you take payments, compare the provider's pricing model, and check its API details and documentation.
Do payment APIs have free plans?
Airwallex Payments and Mollie list free plans. Check the provider's terms to see what the plan includes.
Is a free plan the same as a free trial?
No. A free plan is an ongoing plan with no charge under its terms; a free trial is a time-limited way to try a paid service.

It indicates whether a public API is listed. An API lets software exchange information with a service; review its documentation to see if it suits your needs.
