Event streams

The following endpoints enable you to manage event topics.

API DOMAIN AND NAMESPACE DIFFERENCES FOR EVENT STREAMS

The Event streams APIs are divided into two categories. Each category uses a different domain and namespace.

Public API

The following endpoints use the event-streams domain:

Consume messages POST /api/v1/topics/:topic_id/consume
Publish a message POST /api/v1/topics/:topic_id/publish
Publish a batch of messages POST /api/v1/batch/topics/:topic_id/publish

Refer to the Event streams public API documentation for more information.

Developer API

The following endpoints use the standard Developer API base URL:

List topics GET /api/event_streams/topics
Create a topic POST /api/event_streams/topics
Get a topic by ID GET /api/event_streams/topics/:topic_id
Update a topic PUT /api/event_streams/topics/:topic_id
Purge a topic PUT /api/event_streams/topics/:topic_id/purge
Delete a topic DELETE /api/event_streams/topics/:topic_id

Rate limits

Event streams developer API resources have the following rate limits:

Additionally, Event streams developer API resources have the following payload limit:

Quick reference

Type	Resource	Description
GET	/api/event_streams/topics	Retrieve a list of topics.
POST	/api/event_streams/topics	Create a topic.
GET	/api/event_streams/topics/:topic_id	Get topic by ID.
PUT	/api/event_streams/topics/:topic_id	Update a topic.
PUT	/api/event_streams/topics/:topic_id/purge	Purge a topic.
DELETE	/api/event_streams/topics/:topic_id	Delete a topic.

BEST PRACTICE

For endpoints that modify topics (create and update), we recommend that you define parameters in the request body instead of the URL.

List topics

Retrieves a list of event topics, with optional filtering, sorting, and the ability to include topic schemas in the response.

shell

GET /api/event_streams/topics

Query parameters

Name	Type	Description
name	string optional	Filters event topics by a case-sensitive title. Supports partial matching, which means you can search for fragments of the title.
sort	string optional	Defines how to sort the results. Options include `activity` (most recent activity first), `name`, and `id`. Set to `id` by default.
include_schema	boolean optional	When set to `true`, the schema of each event topic is included in the response payload. Set to `false` by default.

Sample request

This request retrieves event topics that contain the keyword Order within the name. The results are sorted by event topic ID, and the schema for each event topic is included in the response payload.

shell

curl  -X GET "https://www.workato.com/api/event_streams/topics?name=Order&sort=id&include_schema=true" \
      -H 'Authorization: Bearer <api_token>'
