Intro

Introducing Webhooks that allow you to configure your endpoint URL and receive notifications for all your assets including contract, token-type, and token mints. Configure webhooks from the NFT-API product section on the Developer Portal.

NFT-API: Receive notifications for all the successful and failed contract creations, token-type creations, and token mints:

Contract Creation Succeeded
Contract Creation Failed
Token-type creation Succeeded
Token-type creation Failed
Token Mint Succeeded
Token Mint 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:

NFT-API: You can call the check status endpoints using the unique id which is found in the response body for contract creation, token-type creation, and token mints as follows:

How to configure webhooks?

Head over to the Developer Portal.
Click on the product you want to configure webhooks for (NFT API)
Scroll down and click on Create webhook

Add the relevant information:
1. Description: Any sample description of the webhook.
2. Endpoint (POST): The endpoint URL that can accept POST calls.
3. Type: Select your preferred authentication type.
4. Username/ Header name: Enter your custom username or header name (depends on the authentication type you selected.)
5. Password/ API key: Enter your custom password or API key (depends on the authentication type you selected).
6. Finally, click Create.

📘
Authentication is to be set up by you for your endpoint. This allows you to verify that the calls are coming from Venly.

The webhook is created successfully!

Click on the three dots to update or delete a webhook.
