Explaining the Issue

The error code MJ-021 signifies that the Campaign ID provided in your API request does not match any existing campaign in your Mailjet account. This can happen due to typographical errors, outdated references, or incorrect API call configurations.

Step 1: Verify the Campaign ID

Log in to your Mailjet account and navigate to the Campaigns section. Ensure that the Campaign ID you are using in your API call matches an active campaign listed in your account.

Step 2: Update Your API Call

Once you have confirmed the correct Campaign ID, update your API call to include the accurate ID. Double-check for any typographical errors or incorrect parameters in your request.

"method": "GET",
"url": "https://api.mailjet.com/v3/REST/campaign/{correct_campaign_id}",
"headers": {
"Authorization": "Bearer YOUR_API_KEY"
