MDES SDK Guides How to handle output results
wa_api_invoke invocations return an error code and populate a JSON formatted wa_wchar pointer that is passed as a json_out parameter.
The content of this JSON formatted wa_wchar pointer will be dependent on the success/failure error code returned.
Regardless of the success or failure of the wa_api_invoke, you must pass the json_out allocated pointer
to wa_api_free to release the allocated memory back to the process.
Successful call
If this functions returns a successful error code the json_out will be populated with the following:
{
"result" : {
"method" : number,
"code" : number,
"timing" : number,
"timestamp" : string,
"result" : object
}
}Failed call
If this functions returns a failure error code the json_out will be populated with error information:
{
"error": {
"code" : number,
"method" : number,
"errors" : [
{
"code" : number,
"method" : string,
"called_at" : string,
"returned_at" : string,
"message" : string,
"errors" : array
},
...
],
"description" : string,
"define" : string,
"timing" : number
"timestamp" : string
}
}Setup call
This is the expected return from a wa_api_setup call. Each deployed module can return a different configuration object with keys that may only exist for that module. Only the guaranteed keys are shown here.
{
"errors" : [
{
"module" : string,
"code" : number
},
...
],
"configs" : [
{
"timing" : number,
"module" : string,
...
},
...
]
}
