Error doing a POST request Omnis 8.1.3

[Alex Clay]

Hi An,

> [     {         "MerchantOrderNo": 1001598,         "OrderId": 1     } ] 

is different from:

> {
>  "MerchantOrderNo": "string",
>  "OrderId": 0
> }

in two regards. First, you might need to force the value for MerchantOrderNo to be a string so it's quoted:

> [     {         "MerchantOrderNo": "1001598',         "OrderId": 1     } ] 


Second, the square brackets denote an array. The error message you shared suggests the API will be ok with an array, but if changing the string type doesn't help try stripping off the square brackets:

>  {         "MerchantOrderNo": "1001598',         "OrderId": 1     }
