Hello @colnect
Thank you for providing the clarification. If the recurring profiles were created using the Express Checkout API, you have the option to update the amount by running an API call on the profiles.
To assist you with this process, I have included the documentation on updating NVP Express Checkout Recurring Profiles below:
https://developer.paypal.com/api/nvp-soap/update-recurring-payments-profile-nvp/
Please note: For recurring payments made with Express Checkout, the payment amount can only be increased by a maximum of 20% every 180 days, starting from the creation of the profile.
However, if the profiles were created using PayPal Standard, I regret to inform you that the only way to update them is one by one via the PayPal Account.
Thank you,
Jennifer
