Websocket API
ZendHQ provides a websocket API that communicates using JSON-RPC.
Basic Usage
You need a websocket client, such as uswc to connect to the websocket. A number of programming languages have either native websocket support, or can provide it via libraries, extensions, or plugins.
You connect to the websocket via the ZendHQ server's IP or DNS address (for example, 127.0.0.1, localhost) and its port. The default port is 10091, custom ports are defined in the zendhqd.daemon_uri
setting.
The following example uses uswc
:
$ uswc ws://127.0.0.1:10091
Once connected, initialize a session, using the configured ZendHQ token:
{"id":1","method":"session.create","params":{"token":"..."}}
When successful, you receive a response indicating a session has been initialized. At this point, you can proceed to call other request methods in the API as described in the remainder of this document.
Request
A request is a remote procedure call sent by the client to the server. The request is a single JSON object that has the following members:
Member | Description |
---|---|
id | An identifier established by the client |
method | A string containing the name of the method to be invoked |
params | A structured value that holds the parameter values for the method |
id
The id member contains an identifier that contains a string or a number. The server response to the request contains the same identifier.
The clients generates an identifier value for every request and the server responds with the same identifier value.
This member is required.
Note: Set the member to any value you want. We recommend starting with 1 and incrementing from there. Use unique values during a given websocket session; the values only need be unique for a given session.
method
The method member contains the name of the method to be invoked. Method names can include an optional namespace prefix separated with the period character:
[<namespace>.]<methodname>
This member is required.
params
The params member contains a structured value holding the parameter values for the method. Represent parameter values as an array (by position) or as an object (by parameter name).
This member is optional.
Response
The server responds to client requests with a response. The response is a single JSON object that has the following members:
Member | Description |
---|---|
id | The identifier established by the client |
result | The result of the remote procedure call |
error | Error object |
id
The id member is the identifier established by the client and identifies the request to which the response belongs.
This member is required.
result
The result member contains the result of the remote procedure call and is determined by the method invoked on the server. This member is required on success. This member must not exist if there was an error.
error
The error member contains an error object. This member is required if there was an error. This member must not exist on success.
The error object has the following members:
Member | Description |
---|---|
code | A number that identifies the type of the error |
message | A string describing the error |
data | Optional additional information about the error |
The code
member can have one of the following values:
Value | Description |
---|---|
-32700 | Failed to parse JSON |
-32600 |
Invalid request |
-32601 | Requested method not found |
-32602 |
Invalid or missing parameters |
-32603 | Internal server error |
-32000 |
Invalid session |
-32001 | Authentication failed |
-32002 | Not licensed |
Notification
Notifications are events sent by the server to the client. They are not related to any requests made by the client. For most of the notifications the client must first subscribe for the specific type of events.
Notifications are JSON objects with the following members:
Member | Description |
---|---|
event | A string identifying the event |
params | A structured value that holds the parameter values for the event |
event
The event member is a string that identifies the event. Event names can include an optional namespace prefix separated with the period character:
[<namespace>.]<eventname>
This member is required.
params
The params member contains a structured value holding the parameter values for the event. Represent parameter values as an array (by position) or as an object (by parameter name).
This member is optional.
Batch
The client may send several Request objects at the same time by sending a JSON array filled with Request objects.
The server responds with an array containing the corresponding Response objects, after all the batch Request objects have been processed.
The Response objects being returned from a batch may be returned in any order within the array. The client must match contexts between the set of Request objects and the resulting set of Response objects based on the id member within each object.
If the batch rpc call itself fails to be recognized as a valid JSON or as an array with at least one value, the response from the server is a single Response object.

Namespace "jq"
The jq namespace manages Job Queue jobs and queues.
-
A Job Queue job is a task that ZendHQ executes asynchronously on the ZendHQ daemon’s node or optionally on PHP nodes. The job can, for example, perform an HTTP request to a specific server.
-
A Job Queue queue is a scheduler that executes tasks one by one. The execution order is determined by the schedule and priority of jobs. Clients can create multiple Job Queue queues to execute tasks in parallel.
The client must have a session associated with it and the ZendHQ license must be valid.
Queue identifier
Job Queue queues are identified by a name or a numeric ID value. The jq namespace handler allows entering queue identifiers in multiple ways:
-
as a JSON object with elements name or id;
-
as a JSON string value with the name of the queue;
-
as a JSON numeric value with the ID value of the queue.
Queue name must be more than zero and less 256 characters long.
Queue ID value must be a positive integer value including zero.
The special ID value 0 is used to identify the default queue even if the default queue has a different ID value.
The following are valid queue identifiers:
"queue":{"name":"feeds"}
"queue":{"id":2}
"queue":"feeds"
"queue":2
Default Queue
The Job Queue always has a default queue, which cannot be deleted. By default, the default queue is identified by the queue name "__default__". The ID value 0 always identifies the default queue even if the actual ID value is different.

job_id |
Job ID value or JSON array with job ID values (see notes below) |
task_id | Task ID value or JSON array with task ID values (see notes below) |
Without any elements in the subscription filter, the client is subscribed to all the Job Queue notifications events.
With a queue element as an empty JSON array, the client is subscribed to all the queue related events.
With a queue elements as a single queue identifier or a JSON array with queue identifiers, the client is subscribed to specific queue related events.
Elements job_id
and task_id
are currently trigger elements and can have any value. At least one valid queue identifier must be specified in the queue element for these elements to be accepted.
If the job_id
element exists with any values, then the client is also subscribed to all the job related events within specified queues.
If the task_id
element exists with any values, then the client is also subscribed to all the task related events within specified queues.
Notice that the preferred value for job_id
and task_id
elements is an empty JSON array, which is future proof and keeps working the same way when additional job or task filtering is added.
Response
The result member contains the fixed string "OK".
Example
Client subscribes to all the queue and job related notification events in the queue “feeds”:
Client:
{"id":2,"method":"jq.subscribe","params":{"queue":{"name":"feeds"},"job_id":[]}}
Server:
{"id": 2, "result": "OK"}
jq.unsubscribe
method
Unsubscribes the client from Job Queue notification events.
Request

Value | Description |
---|---|
suspended |
JSON boolean true value for creating suspended queues |
