Hi guys!

I am recieving the order payment from customers on my 2checkout merchant account but orders are not being created instead i can see the customers attempt under Abandoned checkouts   

I have tried to place an order myself and the same thing happens and i get this error message "There was a problem with the payment service. Please select a different payment method or try again later".

Anyone have an idea how to solve this issue.

Hi Danyal, 

Nick here from Shopify. 

This is odd and should not be happening if everything is set up in your admin. The statement of "There was a problem with the payment service." would lead me to believe this is something on 2checkouts side of things. It could be worth disconnecting and connecting the payment gateway again and see if that helps to fix it. Alternatively, you could reach out to 2checkouts support team directly to find out what's going on. 

Hope this helps and points you in the right direction for next steps to take. Don't hesitate to reach out again should you have any other questions. 

All the best, Nick

Hi everyone 

I have found how to solve this problem. In order to get this fixed, instead of using the INS secret word,  use BUY Link secret word.
It is suggested to generate a new BUY link secret word and use it. 


If you want to buy the best wireless charger, please visit my store --> 8Blue™| 2019 Best Qi Wireless Chargers for iPhone/Android


I'm not the dropshipping guys. I work in Shenzhen(China) where 95% of the world wireless chargers are made in here.

I have cooperated with several wireless charger factories in Shenzhen. So you can buy almost any wireless charger in the market on my website.


Please leave a message("coming from Shopify") when you buy something from my store, I will give all shopify-er a big discount😘



This is the solution that 2checkout support team sends to me.



Thank you for reaching out to us. I hope my email finds you well. 

The raised issue suggests a communication mismatch between the accounts due to incorrect setup - orders will be processed on 2checkout and be displayed as an abandoned cart on the Shopify side. 

In accordance with our Shopify-2checkout integration documentation 

Sign in to your 2Checkout account. 
Navigate to Dashboard → Integrations → Webhooks & API section 

-Enable return after the sale - checkbox needs to be checked 
-Return method - select header redirect 

Also, Currently, we are experiencing an issue with the INS secret word which may be causing the issues for your account as well. 

In order to get this fixed, instead of using the INS secret word, please use BUY Link secret word which is mentioned here: 

It is suggested to generate a new BUY link secret word and use it. 

Save the new setup and place a live sale to verify the flow(we recommend creating a product of 1$ for testing purposes to minimize the transaction fees). 

Let us know if we can be of any further assistance. 

Kind regards,
Merchant Support Specialist

I had the same issue and this was the solution:


Go to 2checkout Webhooks & API settings and make Instant Notification Service (INS) secret word and Buy link secret word THE SAME. I just generated a new INS secret word and pasted it into the Buy link field and it resolved the problem.


I hope it will help!
