Really strange as I copy paste the code sample from the sendinblue API doc:
OkHttpClient client = new OkHttpClient();
MediaType mediaType = MediaType.parse("application/octet-stream");
RequestBody body = RequestBody.create(mediaType,"\"updateEnabled\":false,\"email\":\"example@email.com\"}");
Request request = new Request.Builder()
.url("https://api.sendinblue.com/v3/contacts")
.post(body)
.addHeader("accept", "application/json")
.addHeader("content-type", "application/json")
.addHeader("api-key", "xxxxxxxxxxxxxxxxxx")
.build();
Response response = client.newCall(request).execute();
The response is:
response code is: 406
response message is: Not Acceptable
response body is: {"code":"not_acceptable","message":"Unacceptable content-type"}
I use this Java client:
<dependency>
<groupId>com.sendinblue</groupId>
<artifactId>sib-api-v3-sdk</artifactId>
<version>3.0.1</version>
</dependency>
You need to set the content-type
in as JSON (application/json).
