Webhooks

Describes how to configure and use webhooks for the Wallet-API.

Intro

Introducing Webhooks that allow you to configure your endpoint URL and receive notifications for all your transactions. Configure webhooks from the Wallet-API product section on the Developer Portal.

Wallet-API: Receive notifications for all the successful and failed transactions carried out on all your wallets.

Transaction Succeeded
Transaction Failed

Retry Mechanism

If your endpoint URL is down, Venly will attempt to resend the notification message five times with an interval of 10 seconds in between to ensure delivery. After the last try, the message will be dropped since we don't store the webhook messages, they're not retrievable anymore.

In case your endpoint is down for more than 50 seconds and you don't receive the message:

Wallet-API: You can call the check transaction status endpoint using the transactionHash of your specific transaction.
