Why did Chargebee send the payment request with "capture_method": "manual"?
Solution
You may receive details from Stripe that Chargebee is sending payment with "capture_method": "manual" but it should be “Automatic”. Chargebee uses Auth-Capture flow.
The first authorization of the payment is done when Chargebee will check the customer's credit card to check the availability of the authorized amount. Then, a hold will be placed on the card for that amount for a particular tenure.
Post success of authorization, Chargebee initiates another call to actually collect authorized funds.
As the capture is initiated from Chargebee we set the capture method as “manual”
