Using the Rapyd API to Create Your First Customer

Now more than ever, businesses are looking to rapidly grow and transform digitally to meet the demands of consumers, for more convenient, faster service. For about 85% of businesses (across all industries) undergoing a digital transformation, APIs played a significant role in the company’s digital efforts. (Postman)  Onboarding and managing your customer with the right tools and access to payment options is important for a growing relationship. 

The Rapyd API has access to hundreds of payment methods in 100+ countries allowing clients to enter new markets and create customers using their preferred payment method. Managing customers with the Rapyd API provides you with the tools to take control of their checkout experience by linking their information to a unique ID to safely save their payment details for future use. This includes saving card or bank account details, or making payments to your website with cash or local ewallets. Customers can avoid having to input their payment method details for every transaction, and maintain an on-going relationship with your business. You can download our Postman Collection and begin testing to create your customers now. 

What is a Customer within the Rapyd API?

A customer within the Rapyd API is a profile with a unique ID representing a person or business that pays for a product or service. This could be somebody paying to take an online course, or a business making a large order purchase off of a b2b eCommerce website. 

Part of a great customer experience is making things easier and more convenient for your users. Your customer’s sensitive information is securely saved, so they can have a quicker return experience. 

Steps to Create Your First Customer 

Here’s how to create a customer with a payment method using the Rapyd API.

After you sign up in Client Portal, make sure you download our Postman Collection and input your rapyd_access_key</var/strattic/site/public_html> and rapyd_secret_key</var/strattic/site/public_html> and you can begin with your first API call in step 2. 

Step 2: List Payment API
