Maileon Webhook Inspector

Inspect Maileon Webhook Calls

A private, encrypted endpoint that captures and displays your Maileon webhook payloads — no account required.

1

Generate your vault

Click "Generate new vault". A random, unique vault ID is created — this ID is your access key.

2

Save your vault ID

Copy and store your vault ID. You will need it to reopen this vault in a new browser session.

3

Configure Maileon

In your Maileon account go to Settings → Webhooks and paste the generated webhook URL.

4

Inspect the data

Trigger a test event in Maileon and return here to view the captured payload with full headers and body.

Configure the webhook in your Maileon account as shown below.

Get started

Generate a new vault or reopen an existing one using its vault ID.

New vault

Creates a unique random vault and webhook URL.

Reopen existing vault

Paste the vault ID you saved when you first created it.

Access & privacy: Your vault ID is your only credential — anyone with your vault ID can view your calls. Keep it private and do not include sensitive data in webhook payloads. Calls are stored AES-256 encrypted, retained for a maximum of 7 days (last 5 calls), and can be deleted at any time from within the vault.
