Step 1) Create a SumUp Account

Step 2) Log in to your SumUp Account on SumUp's Developer Portal

In order for you to get the required information to integrate SumUp with your website, you'll need to log in to your account using the link below:

https://developer.sumup.com

Then simply:

a) Press the 'Login' button in the top right-hand corner

b) Enter your account credentials and log in

 

 

Step 3) Generate required keys

You'll now need to generate some credentials so we can integrate with your SumUp account. To do this simply:

 

a) From the top right-hand corner, click 'Account'

 

b) Click 'API Keys' from the dropdown

 

c) You'll see a key called 'Public key' already there. Where it says 'Token', simply copy this token and save it for later use

 

d) Next, you'll need to generate a 'Secret key'. To do this, under 'Name your API key', enter 'Website' and then press the 'Create' button

 

e) You'll then be prompted with a window showcasing your secret key. Either download this or copy it, but make sure to save it for later use, as once you click off this window you won't be able to see it again

 

 

Step 4) Find your merchant account ID

When you create an account with SumUp, you'll be assigned a unique ID called the merchant account ID. To find this simply:

 

a) Navigate to https://www.sumup.com/en-us/ and log in to your account

b) After logging in to your account, you'll see your merchant ID in the top right corner as seen in the screenshot below. Make a note of this as you'll need it later.

 

Your merchant account ID is the code below your company name as see in the below screenshot

 

Step 5) Enter all the information into your website manager

 

1) Log in to your website manager

2) From the left-hand menu, select 'Settings' then 'Shop settings'

3) Click the 'Payment provider' tab

4) Click 'SumUp'

5) Scroll down to the section called 'General & Authentication'

6) Enter your 'Merchant Code' into the Merchant Code field

7) Enter your 'Public key' into the Public key field

8) Enter your 'Secret key' into the Secret key field

9) Press the 'Update' button at the top or bottom of the page

 

 

Step 6) Make sure it's all working

Now that you've added your SumUp details, it's important to ensure that everything is working, as the last thing you'd want is for customers not to be able to check out on your website.

As such, you can check that SumUp is working by:

1) Logging into your website manager

2) From the top right-hand corner, press 'Open website'

3) Add an item to your basket and go through the checkout process

4) On step 4 of the checkout process, click the checkout button below SumUp

5) If this page opens to the SumUp payments widget, then your integration is working and all set up correctly. If not, then chances are you entered something incorrectly, so go through the previous steps again to make sure you've done everything correctly.
