TM1 Rest API - tm1.Execute return 278 error

[danz]

I recently started learning REST and been going through IBM Planning Analytics TM1 REST API pdf file.

I run following request in Postman and receive 278 error.
POST /api/v1/Cubes('Metrics cube-Sales')/Views('Metrics cube-Sales')/tm1.Execute?$expand=Cells

Code: Select all

{
    "error": {
        "code": "278",
        "message": "The content type specified is not supported. Please use JSON (application/json; charset=utf-8) as the content type."
    }
}

While GET /api/v1/Cubes('Metrics cube-Sales')/Views('Metrics cube-Sales') returns result.

Any idea where has gone wrong?

Thanks in advance.

Hi danz:

I know many TM1 error messages aren't that helpful, but in this case it is telling you exactly what you need to do. You need to add a Header in Postman for Content-Type and specify the value it's asking for:

content-type-example.jpg (10.5 KiB) Viewed 4795 times

This header is part of the request that makes its way to TM1 and lets it know how the contents of your request body are formatted. Yes, that's also the format it's expecting, but you need to explicitly say that in the header that you're sending.

Hope that helps!
Mike
