Stripe Payment Intents

Stripe Payment Intents is a SCA-compliant payment gateway to process payments from customers within the European Economic Area (EEA).

Stripe Payment Intents is a SCA-compliant Stripe service that lets you process card payments from customers located in the European Economic Area (EEA). Strong Customer Authentication (SCA) is a legal requirement in the EEA as part of the Revised Payment Services Directive (PSD2). This includes a two-factor authentication for online payments across Europe to help reduce the incidence of payer fraud.

Your online card transactions must be SCA-compliant if your business payment provider and your customer's payment provider are both located within the European Economic Area. If only one party is located in the EEA, the directive remains to show one's 'best efforts' to implement SCA.

Requirements to Integrate Stripe Payment Intents 

You need to make sure some requirements are met before you can integrate Stripe Payment Intents with Nexudus. The following requirements detail what you need to do before starting the integration process. 

Requirement 1 - Create a Stripe account

If you don't have a Stripe account, we recommend you create your account via their website or get in touch with their team via their contact form.

Requirement 2 - Open a Text Document to Temporarily Store Information 

You will need some of information collected in step one and two during the third step of the integration process. To make sure you have this information readily available during step three, open a document in any word processing tool such such as Google Docs, Word, Notepad or Notes. You'll be able to copy and paste information in that file and store it until you've completed the integration

  • Your Stripe API secret key

Step 3 -  Enabling  Stripe Payment Intents in Nexudus 

Once you've gathered all the necessary information from your Stripe account, you can enable Stripe Payment Intents as a payment gateway in Nexudus. 

  1. Log in to your Nexudus account if you aren't logged in.
  2. Click on the Payment Methods tab.

  6. Paste the Stripe webhook signing secret you copied from your text document in the Webhook Signing Secret field.


  7. Click Save changes.

Step 4 - Updating your Template Files in Nexudus

This step only applies if you've opened an account with Nexudus before June 25th 2020 and you haven't updated your template files.

Once you've added Stripe Payment Intents as a payment method in your Nexudus account, the last step is to update your payment template files.

  1. Click on Settings > Website > Templates.
  2. Click on Template Files.
  3. Select the payment_scripts.htm file and click Update.
  4. Select the payment_history.htm and click Update.
  5. Select the gateway_payment_form.htm and click Update. 


At this point, the Stripe Payment Intents integration is complete. We recommend you test the integration by raising a test invoice and paying it using Stripe Payment Intents.

Once you've made sure invoice payments work, you can delete the payment gateway that Stripe Payment Intents replaced. You can also close the text document you used to store the information needed for the integration without saving it.
