Hi All,

I am facing an error when trying to post a JSON payload from POSTMAN to Business Central.

I have copied the function "ReadJSON" from https://www.dvlprlife.com/2022/12/dynamics-365-business-central-read-a-json-file-with-al/ and using the same customer payload on the page.

Please attached the screenshots.

The error being encountered is below:

{
    "error": {
        "code": "BadRequest",
        "message": "The parameter 'Customer' in the request payload is not a valid parameter for the operation 'ExperimentsAPI_ReadJSON'.  CorrelationId:  49c0c920-0585-4dc6-9fe2-6bdddb2db9e7."
    }
}

Can anyone please advise or help. Thank you.

Regards,

Thank you very much all. Issue has been solved. As Bilal pinpointed, it was due to the variable name being wrong on the function.

Hi,

Your procedure is expecting a string named JsonObjectText but you are sending with the name "Customer" in the payload.
