Mailjet Email API credentials

Used by 2 BusyBot nodes.

Type mailjetEmailApi 3 fields

The Mailjet email credential needs a key pair — an API key and a secret key — issued together in your Mailjet account. It also carries a sandbox switch that validates sends without delivering them, which is what you want while building.

Fields

FieldTypeRequiredNotes
API Key
apiKey		 password Yes Your Mailjet API Key.
Secret Key
secretKey		 password Yes Your Mailjet Secret Key.
Sandbox Mode
sandboxMode		 boolean No When enabled, API calls are validated without delivering messages.

Getting your credentials

  1. Sign in to Mailjet.
  2. Open the API key management area of your account settings.
  3. Copy the API Key and its matching Secret Key. They are issued as a pair and only work together.
  4. Paste both into the credential in BusyBot.
  5. While testing, enable Sandbox Mode — Mailjet validates the request fully but delivers nothing. Turn it off before going live.

Permissions and scopes

The key pair acts on the Mailjet account that issued it. Sending also requires the sender address or domain to be validated in Mailjet, which is a separate step from authentication.

Troubleshooting

  • 401 Unauthorized — the key and secret are from different pairs, or one was regenerated.
  • Sender not allowed — the from address or its domain has not been validated in Mailjet.
  • Everything succeeds but no email arrives — Sandbox Mode is still enabled.

Frequently asked questions

What does Sandbox Mode do?

Mailjet validates the request end to end but delivers nothing. It is ideal while building — and the first thing to check if sends report success but nothing arrives.

Why are there two keys?

Mailjet issues an API key and secret key as a pair and authenticates on both. Mixing keys from different pairs fails.

Why are my sends rejected even though authentication works?

The sender address or domain must be validated in Mailjet. Authentication and sender validation are separate checks.
