Frequently Asked Questions
What is an invoice API?
An application programming interface (API) is essentially a communication protocol that serves as an intermediary between different software components. In simpler terms, it’s a set of procedures that applications use to interact with each other. APIs are integral to modern technology because they allow isolated systems to share data and functionalities, resulting in more sophisticated and interconnected digital solutions.
When it comes to invoicing, an API can automatically push and pull data between the different systems involved in the generation, transmission, and management of invoices. That enhances invoicing efficiency and accuracy by using software-to-software communication, enabling swift invoice processing, reduced errors, and simpler accounts receivables management.
What is a payment API?
A payments API or bill pay API allows merchants to flexibly integrate various payment methods into their platforms. That allows businesses to quickly scale their payments offerings and adapt to different markets by enabling or disabling specific payment methods as required. By streamlining the transaction process, payment APIs enhance customer experience, increase efficiency, and offer secure payment solutions tailored to diverse market demands.
Is an API a payment gateway?
An API is not a payment gateway, but rather a tool that facilitates communication between different software applications. A payment gateway, which authorizes and processes transactions, uses an API to interact with other systems—like merchant websites.
While a payment gateway securely transmits customer information and processes transactions, the API sends the transaction data to the gateway and then sends the response back to the website. Thus, while an API is a vital piece of how a payment gateway operates, it is not the gateway itself.
How does API billing work?
API billing typically involves charging for API usage based on the number of calls, the volume of data transferred, or the level of features used. API providers typically adopt usage-based pricing models on a per-transaction or per-subscription basis, often with minimum monthly commitments. To learn more about Tight's billing models, reach out to a sales representative.
How do you define invoicing vs. billing?
"Invoicing" refers to creating and sending a detailed list of goods or services provided, usually toward a future payment. On the other hand, "billing" can be less detailed. It typically involves generating a simple statement of charges, often demanding immediate payment.
In the simplest terms, invoicing concerns future payments, while billing concerns urgent payments.
