Hi @hieuntg81 ! Welcome to the forum! Thank you for taking an interest in trying out Coinbase APIs. It seems like the transfer you mentioned was made off-chain. Transactions sent off-chain and/or to an email address, for example, won’t generate any notifications. You will only receive notifications once a new payment/transfer has been made on-chain and for a crypto address.
Hi @hieuntg81! Thank you for patiently waiting as we looked into your query. As what we have initially stated, users will only receive notifications once a new payment/transfer has been made on-chain and for a crypto address . Hence, when your Coinbase wallet receives funds from another Coinbase wallet through an on-chain transaction, then you should be able to get a notification. Otherwise, we regret to inform you that we currently do not have a workaround for receiving notifications for off-chain transactions. You can visit the link for further reference on currently supported notifications.
We hope this helps! Please feel free to reach us if you have further questions. Have a good day!
