HRESULT HCHttpCallResponseSetResponseBodyBytes(  
         HCCallHandle call,  
         const uint8_t* bodyBytes,  
         size_t bodySize  
)  
```

### Parameters

*call*   \_In\_\
Type: HCCallHandle

The handle of the HTTP call.

*bodyBytes*   \_In\_reads\_bytes\_(bodySize)\
Type: uint8\_t\*

The response body bytes of the HTTP call.

*bodySize*   \_In\_\
Type: size\_t

The length in bytes of the body being set.
