Trying to change a plan for a user with proration immediately

curl -X POST "https://live.dodopayments.com/subscriptions/$SUBSCRIPTION_ID/change-plan"
-H "Authorization: Bearer $DODO_PAYMENTS_API_KEY"
-H "Content-Type: application/json"
-d '{
"product_id": "PROD_ID_OF_NEW_45_PLAN",
"quantity": 1,
"proration_billing_mode": "prorated_immediately"
}'

via API call and Dodo dashboard but both fails. User has active subscription of 40$

i have created a new product 45$ which i want to upgrade to Please help. @shadow laurel

Your request looks correct — this usually fails due to payment or product config issues, not the API format.

Check these quickly:

• Payment method on subscription

  • prorated_immediately triggers an instant charge
  • If the customer has no valid payment method, it fails
  • Try adding:
    • "on_payment_failure": "prevent_change" (to see failure cleanly)

• Product mismatch

  • Ensure the new $45 product:
    • Same billing interval (monthly vs yearly)
    • Same currency
  • Mismatches will cause plan change failure

• Subscription state

  • Must be active
  • Not past_due, incomplete, or canceled

• Try safer proration mode

  • Use "difference_immediately" instead
  • More reliable for upgrades (charges only $5 delta)

• Check API error response

  • Dodo returns a specific error (payment_failed, invalid_product, etc.)
  • That message is key — share it if still stuck

If it still fails, paste the exact API error — that’ll pinpoint it fast.

@shadow laurel I think if someone can remve that require payment method entry from DB i can initiate plan change.

[shadow laurel]

Yeah, got it. Let me check with the team on this on Monday.

@shadow laurel update?

[warped warren]

@crimson birch @shadow laurel @remote vigil Client is awaiting payment. Service is disrupted.

It seems the customer initiated an update to the payment method but did not complete the process. As a result, the payment has been marked as requires_payment_method. Please ask your customer to try updating the payment method again and ensure the payment is successful. After that, they can proceed with the plan change.

Can you share me the steps i send out to customer?

@shadow laurel I think same message you have drafted at around 1pm and then sent and deleted and then send back again at 2:35

Please ask your customer to login to customer portal and flow steps mentioned in the documentation - https://docs.dodopayments.com/features/customer-portal#payment-method-update-flow

[shadow laurel]

We were not fully sure about the response, as we needed input from our tech team. We have consulted with them, and responded noww
