Confluent REST Proxy API Reference¶
For a tutorial using the Confluent REST Proxy API see this step-by-step guide.
Content Types¶
The REST Proxy uses content types for both requests and responses to indicate these data properties:
Serialization format:
json
API version (e.g.
v2
orv3
)Embedded formats:
json
,binary
,avro
,protobuf
andjsonschema
Important
The
jsonschema
andprotobuf
embedded types are supported beginning with REST Proxy v2.
REST Proxy supports the Avro®, JSON Schema,
and Protobuf serialization formats. The versions
of the REST Proxy API are v2
and v3
.
The embedded format is the format of data you are producing or consuming. These formats
are embedded into requests or responses in the serialization format. For
example, you can provide binary
data in a json
-serialized request; in
this case the data should be provided as a base64-encoded string.
- For
v2
, the content type will beapplication/vnd.kafka.binary.v2+json
. - For
v3
the content type will beapplication/json
.
If your data is JSON, you can use json
as the embedded format and embed it directly:
- For
v2
, the content type will beapplication/vnd.kafka.json.v2+json
. - For
v3
the content type will beapplication/json
.
With avro
, protobuf
, and jsonschema
embedded
types, you can directly embed JSON formatted data along with a schema (or schema ID) in the request.
These types use Schema Registry, and the ID of the schema is serialized in addition to the data and payload.
- The Avro content type is
application/vnd.kafka.avro.v2+json
. - The Protobuf content type is
application/vnd.kafka.protobuf.v2+json
. - The JSON schema content type is
application/vnd.kafka.jsonschema.v2+json
.
The format for the content type is:
application/vnd.kafka[.embedded_format].[api_version]+[serialization_format]
For more information, see Schema Registry API Reference.
The embedded format can be omitted when there are no embedded messages
(i.e. for metadata requests you can use application/vnd.kafka.v2+json
).
The preferred content type for v2
is application/vnd.kafka.[embedded_format].v2+json
.
However, other less specific content types are permitted, including application/vnd.kafka+json
to indicate no specific API version requirement (the most recent stable version
will be used), application/json
, and application/octet-stream
. The
latter two are only supported for compatibility and ease of use. In all cases,
if the embedded format is omitted, binary
is assumed. Although using these
less specific values is permitted, to remain compatible with future versions you
should specify preferred content types in requests and check the content types
of responses.
Your requests should specify the most specific format and version information
possible via the HTTP Accept
header
For v2
, you can specify format and version as follows:
Accept: application/vnd.kafka.v2+json
For v3
, do not specify the version. The latest version (v3
) will be used:
Accept: application/json
The server also supports content negotiation, so you may include multiple, weighted preferences:
Accept: application/vnd.kafka.v2+json; q=0.9, application/json; q=0.5
This can be useful when, for example, a new version of the API is preferred but you cannot be certain it is available yet.

REST API Usage Examples (curl), which show how to test the APIs from the command line using curl
Errors¶
All API endpoints use a standard error message format for any requests that return an HTTP status indicating an error (any 400 or 500 statuses). For example, a request entity that omits a required field may generate the following response:
HTTP/1.1 422 Unprocessable Entity
Content-Type: application/vnd.kafka.v3+json
{
"error_code": 422,
"message": "records may not be empty"
}
Although it is good practice to check the status code, you may safely parse the
response of any non-DELETE API calls and check for the presence of an
error_code
field to detect errors.
Some error codes are used frequently across the entire API and you will probably want to have general purpose code to handle these, whereas most other error codes will need to be handled on a per-request basis.

Consumers¶
The consumers resource provides access to the current state of consumer groups, allows you to create a consumer in a consumer group and consume messages from topics and partitions. REST Proxy can convert data stored in Kafka in serialized form into a JSON-compatible embedded format. These formats are supported:
- Raw binary data is encoded as base64 strings
- Avro data is converted into embedded
- JSON objects, and JSON is embedded directly
- Protobuf
- JSON Schema
Because consumers are stateful, any consumer instances created with the REST API are tied to a specific REST Proxy instance. A full URL is provided when the instance is created and it should be used to construct any subsequent requests. Failing to use the returned URL for future consumer requests will result in 404 errors because the consumer instance will not be found. If a REST Proxy instance is shutdown, it will attempt to cleanly destroy any consumers before it is terminated.
-
POST
/consumers/
(string: group_name)¶ Create a new consumer instance in the consumer group. The
format
parameter controls the deserialization of data from Kafka and the content type that must be used in theAccept
header of subsequent read API requests performed against this consumer. For example, if the creation request specifiesavro
for the format, subsequent read requests should useAccept: application/vnd.kafka.avro.v2+json
.Note that the response includes a URL including the host since the consumer is stateful and tied to a specific REST Proxy instance. Subsequent examples in this section use a
Host
header for this specific REST Proxy instance.Parameters: - group_name (string) – The name of the consumer group to join
Request JSON Object: - name (string) – Name for the consumer instance, which will be used in URLs for the consumer. This must be unique, at least within REST Proxy process handling the request. If omitted, falls back on the automatically generated ID. Using automatically generated names is recommended for most use cases.
- format (string) – The format of consumed messages, which is used to convert messages into
a JSON-compatible form. Valid values: “binary”, “avro”, “json”, “jsonschema”,
and
protobuf
. If unspecified, defaults to “binary”. - auto.offset.reset (string) – Sets the
auto.offset.reset
setting for the consumer - auto.commit.enable (string) – Sets the
auto.commit.enable
setting for the consumer - fetch.min.bytes (string) – Sets the
fetch.min.bytes
setting for this consumer specifically - consumer.request.timeout.ms (string) – Sets the
consumer.request.timeout.ms
setting for this consumer specifically. This setting controls the maximum total time to wait for messages for a request if the maximum request size has not yet been reached. It does not affect the underlying consumer->broker connection. Default value is taken from the REST Proxy config file
Response JSON Object: - instance_id (string) – Unique ID for the consumer instance in this group.
- base_uri (string) – Base URI used to construct URIs for subsequent requests against this consumer instance. This
will be of the form
http://hostname:port/consumers/consumer_group/instances/instance_id
.
Status Codes: - 409 Conflict –
- Error code 40902 – Consumer instance with the specified name already exists.
- 422 Unprocessable Entity –
- Error code 42204 – Invalid consumer configuration. One of the settings specified in the request contained an invalid value.

Query Parameters: - timeout – Maximum amount of milliseconds the REST Proxy will spend fetching records. Other parameters controlling actual time spent fetching records: max_bytes and fetch.min.bytes. Default value is undefined. This parameter is used only if it’s smaller than the consumer.timeout.ms that is defined either during consumer instance creation or in the REST Proxy’s config file.
- max_bytes – The maximum number of bytes of unencoded keys and values that should be
included in the response. This provides approximate control over the size of
responses and the amount of memory required to store the decoded response. The
actual limit will be the minimum of this setting and the server-side
configuration
consumer.request.max.bytes
. Default is unlimited.

REST Proxy API v3¶
These APIs are available both on Confluent Server (as a part of Confluent Enterprise) and REST Proxy. When using the API in Confluent Server,
all paths should be prefixed with /kafka
. For example, the path to list clusters is:
- Confluent Server:
/kafka/v3/clusters
- REST Proxy:
/v3/clusters
Confluent Server provides an embedded instance of these APIs on the Kafka brokers for the v3 Admin API.
The embedded APIs run on the Confluent HTTP service, confluent.http.server.listeners
. Therefore, if
you have the HTTP server running, the REST Proxy v3 API is automatically available to you through the brokers.
Note that the Metadata Server (MDS) is also running on the Confluent HTTP service,
as another endpoint available to you with additional configurations.
Tip
To learn more, see the following sections:
- REST API Usage Examples (curl) for how to test these API endpoints from the command line. from the command line
- Admin REST APIs Configuration Options
- Admin operations in Kafka REST API Features
- Confluent Admin REST APIs demo
