To check status of any payment on Elite PG, the merchant needs to run Order Status api with own system ORDER_ID.

curl  --request POST \
 --url {api_base_url}/status \
 --header 'Content-Type: application/json' \
 --header 'order-source: rest-api' \
 --header 'x-client-id: <App ID>' \
 --header 'x-client-secret: <Secret Key>' \
 --data '{
  "order_id": "order_1626945143520"
  }'
