Support » Plugin: SumUp Payment Gateway For WooCommerce » Failed to get Checkout ID to process payment

  • Resolved jackmclean


    Checkout fails immediately with ‘Failed to get Checkout ID to process payment’. I’ve double checked the credentials are correct. Is this a known issue or something I have missed?

  • Just getting the exact same issue. probably something to do with the Developers setup in Sumup. Am investigating further.

    On the Sumup setup it says – For all Webshop plugins and direct integration, make sure your account is fully on-boarded before purchasing the plugin or starting the integration. Please share your client_id to activate the “Payments” scope at

    I’m guessing this is the culprit.

    Hi @jackmclean, Hi @cgain,

    This is correct, some restrictions are applied by default on SumUp account, please contact with your SumUp merchant ID, we will help you for the onboarding process and activate the permission for your account to accept online payments.

    Many thanks,

    I have now had mine approved, but it still fails. No logged errors just fails and suggests a different payment method. I’ll post if I can get some errors.



    Had a prompt reply this morning from Sumup saying they had activated the Client for taking payments on the website. Just tested and now working OK.

    Please email

    They will need to activate your payment scope on your account.


    Hello @julliansumup ,

    Do I also have to send this email in order to activate payment scope for a test account?



    I installed the plugin today, created credentials, enabled test mode, tried to do a checkout with 1 euro and I get this error, too.

    What shall I do?

    I would like to enable online payments to the test credentials and the real ones.

    Where do I have to send the email to do that? or ?

    I have the samme question a theart8, please advise

    @agoralive just contact them via email, the integration one. Basically they have to activate your SumUp account to process online payments

    When we had this issue I did what was asked and emailed they did whatever it is they do on their end and it started working. However a few months later the checkout error has returned


    After contacting SumUp a number of times they say that the issue is fixed and the account is activated but the error is still there.

    What can we do?
