Get events from an event queue
GET {{ api_url }}/v1/events
This endpoint allows you to receive new events from a registered event queue.
Usage examples
{start_tabs} {tab|python}
#!/usr/bin/env python
import sys
import zulip
# Pass the path to your zuliprc file here.
client = zulip.Client(config_file="~/zuliprc")
# If you already have a queue registered and thus, have a queue_id
# on hand, you may use client.get_events() and pass in the above
# arguments, like so:
print(client.get_events(
queue_id="1515010080:4",
last_event_id=-1
))
call_on_each_message
and call_on_each_event
will automatically register
a queue for you.
{tab|js}
More examples and documentation can be found here.
const zulip = require('zulip-js');
// Pass the path to your zuliprc file here.
const config = {
zuliprc: 'zuliprc',
};
zulip(config).then((client) => {
// Register queue to receive messages for user
const queueParams = {
event_types: ['message']
};
client.queues.register(queueParams).then((res) => {
// Retrieve events from a queue
// Blocking until there is an event (or the request times out)
const eventParams = {
queue_id: res.queue_id,
last_event_id: -1,
dont_block: false,
};
client.events.retrieve(eventParams).then(console.log);
});
});
{tab|curl}
{generate_code_example(curl, include=["queue_id", "last_event_id"])|/events:get|example}
{end_tabs}
Arguments
{generate_api_arguments_table|zulip.yaml|/events:get}
Note: The arguments documented above are optional in the sense that
even if you haven't registered a queue by explicitly requesting the
{{ api_url}}/v1/register
endpoint, you could pass the arguments for
the {{ api_url}}/v1/register
endpoint to this
endpoint and a queue would be registered in the absence of a queue_id
.
Response
Return values
events
: An array (possibly zero-length ifdont_block
is set) of events with IDs newer thanlast_event_id
. Event IDs are guaranted to be increasing, but they are not guaranteed to be consecutive.
Example response
A typical successful JSON response may look like:
{generate_code_example|/events:get|fixture(200)}
BAD_EVENT_QUEUE_ID errors
If the target event queue has been garbage collected, you'll get the following error response:
{generate_code_example|/events:get|fixture(400)}
A compliant client will handle this error by re-initializing itself (e.g. a Zulip webapp browser window will reload in this case).
See the /register endpoint docs for details on how to handle these correctly.
