Managing your payments as a small business can be complicated - whether you’re managing it via your website or app. This is where an API integration can help.

In this post we’ll take a look at some of the APIs that can help you automate and manage your payments, to make your finances a little less complicated - such as the Wise open API.

Before we get started, here is an overview of some key terms related to APIs. Already know how API works? Check out the APIs in this post.

What is a Payment API?

An API, essentially specifies how components will interact. When computers talk to each other, humans can do less copy-paste between applications. APIs are widely used in every software developed.

A payment API is for managing payments by integrating business tools from your favourite providers, to allow you to automate and better manage your payments and finances.

What does API stand for?

API stands for Application Programming Interface (API), and it allows software applications (programs) to communicate with one another.

API Token

An API token is a unique identifier that an app or website can use to access the API of other companies, like Wise. You can generate an API tokens from a sandbox environment or usually from your account with a provider.

What is an API Key?

An API key is the code used by computer applications. It’s allows the program or application to call the API in order to identify its user or developer to a website.

Sandbox environment

A sandbox is a testing environment that allows you to test software and code in an isolated environment. This allows developers to test features and build integrations. With an API token, your developers will be able to create seamless payouts and account automations.

API Documentation (docs)

API documentation is a quick and useful guide containing what you need to know to integrate a provider’s API.

What is a batch payment?

A batch payment is where multiple invoices, bills or payments is made in a single transaction. For example, if you’re paying all the staff in your payroll at once, or paying all of your outstanding bills.

With payout APIs you can automate payouts and streamline your workflows - and with some providers, like Wise, you can do all this for no extra charge or premium subscriptions.

  2. Make sure you have 2FA enabled.
  3. Scroll down to the end of the Settings page.
  4. Create a read-only token (for security purposes) and start building.

You don’t need to be a business or a bank to use the API, and there are no extra charges or premium subscriptions. And it only takes a few minutes to get started.

  2. Start playing! All new sandbox environments are pre-funded with 1,000,000 GBP of test credit. So there's no need to use your own money. If you don't want to play, go right to your account page.

  4. Get ready to go live. Follow the going live checklist. If your business account is new, make sure you're also verified and 2-step login is set up.
