All,
I am trying to implement a batch request to Dynamics CRM with the following source code:
public async Task<HttpResponseMessage> HttpPatchCrmApi(string resource, string data)
{
string uniq = Guid.NewGuid().ToString();
MultipartContent content = new MultipartContent("mixed", "batch_" + uniq);
HttpRequestMessage batchRequest = new HttpRequestMessage(HttpMethod.Post, CrmBaseUrl + "/api/data/v8.0/$batch");
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, CrmBaseUrl + resource);
request.Content = new StringContent(data, Encoding.UTF8, "application/json");
HttpMessageContent query = new HttpMessageContent(request);
content.Add(query);
batchRequest.Content = content;
HttpResponseMessage response = await RbWebApi.SendAsync(batchRequest);
return response;
}
The problem is that I am getting " 400 Bad request "
EDIT: As suggested in the comments here is the stack trace of the request from fiddler:

While writing the code I was inspiring myself from here and here
I think your request is wrong. You must build the request Body EXACTLY like defined by Microsoft
This means the Blank lines must be there at the right place all the attributes must exist in the body (like "--changeset_XXX" for example) and as I see you dont meet this requirements.
I just build a Request in Postman against my CRM and it worked:
URL
https://yourTenant.api.crm.dynamics.com/api/data/v8.0/$batch
Headers
OData-MaxVersion:4.0
OData-Version:4.0
Accept:application/json
Authorization:Bearer aVeryLongStringTokenHere
Content-Type: multipart/mixed;boundary=batch_1234567
Body
--batch_1234567
Content-Type:multipart/mixed;boundary=changeset_555666
--changeset_555666
