Consume Rest API (400 Bad request)
Question

Hey Guys,


I was trying to integrate Mailjet Services through Rest API,

When i test that from test window. Its working and i am getting the exact response.


This is the Request Body

{
    "Messages":[
      {
        "From": {
          "Email": "support@sportsmadeez.com",
          "Name": "Sports Made Easy"
        },
        "To": [
          {
            "Email": "Kvasan@mygamesolutions.com",
            "Name": "Keerthi"
          }
        ],
        "TemplateID": 593942,
        "TemplateLanguage": true,
        "Subject": "Your official USTA Ranking Update",
        "Variables": {
    "UserName": "Andrew Spurck",
    "RankingClickhere": "https://mgsi-dev.outsystemsenterprise.com/CoreCommonItems/Ranking.aspx?Unsubscribe=false&PlayerId=164667",
    "UnsubscribeClickhere": "https://mgsi-dev.outsystemsenterprise.com/CoreCommonItems/Ranking.aspx?Unsubscribe=true&PlayerId=164667"
    }
      }
    ]
  }


And the Response Body (Success)

HTTP/1.1 200 OKContent-Type: application/json; charset=UTF-8(Show all headers)

 "Messages": 

[    {      

"Status": "success",     

 "CustomID": "",      

"To": [        

{          "Email": "Kvasan@mygamesolutions.com",          

"MessageUUID": "552f3116-47ce-4ac0-ae22-a2393bd63fec",          "MessageID": 288230376198937558,          "MessageHref": "https://api.mailjet.com/v3/REST/message/288230376198937558"        }      ],      "Cc": [],      "Bcc": []    }  ]}



But when I try to pass values through assigns in Logic, it throws me 400 BAD REQUEST


these were the steps I have done

1. added the local variable


2. Assign values for FROM 

3. Assign values for TO, since the TO is a list type, I have added a local variable of the structure(TO) and appended the values


4. Assigned the remaining values

 

5. I checked through breakpoint to verify the values were passed or not, every value was assigned correctly

When I try to step over during breakpoint scenario, it's not even responding anything

Is there anything wrong in the assign values.


I got confused because I have hardcoded the same values in test request body in REST, it was a successful response.

Does anyone have any Suggestion/Solution?

Hi Keerthi,

Have you set the debug level of the REST API to "Full", so that you can see what request has actually been sent?

Hi Keerthi.

Did you check mailjet documentation for the Send method?

https://dev.mailjet.com/guides/#send-api-errors

The API should be returning a Messages structure with a detailed error.
