Canceling a request will immediately close the customer’s executable order request within our system.
It is highly recommended that you require the customer to input some sort of security key (i.e. pin, OTP, etc…) before making the PUT request to cancel an order request.

Canceling an order request

Make a PUT request to /requests
  curl --request GET \
    --url https://api.staging.pipevest.com/v1/ussd/requests?customerId=123456&symbol=AAPL&orderType=PURCHASE
    --header 'Authorization: Bearer 123456' \
    --header 'Signature: sig1=:OTEyMjY4...A5NTNDMEQ=:' \
