Active Subscription: To review or update your payment details on an active subscription, go to your Manage Subscription page on midjourney.com. Make sure you're logged in if you haven't done so already.
From there, click the "Edit Billing" button. This opens your billing portal in a new window. Inside the portal, you can add new card details by clicking "Add a payment method." Click the ... (ellipsis) button to set a card as your default payment method. If you need to delete a payment method, use the X button, but remember you must keep at least one payment method on file as long as your subscription is active.
For smooth transactions, ensure your billing address matches the address on file with your credit card issuer. This helps avoid any unsuccessful payments.
Inactive Subscription: If your subscription has ended, you won't see an "Edit Billing" button on your Manage Subscription page. Instead, enter your email address here. You will receive an email with a link to access your billing portal within a few minutes. Make sure to check your spam folder if you don't receive it right away.
Please note, if you also have a subscription to Midjourney Magazine using the same email address, the form might send you a link to your magazine subscription billing portal instead. If this occurs, or if you encounter any other issues accessing your billing history, please reach out to billing support for assistance.
