Root Endpoint

The root endpoint for the public API is https://api.zenhub.com/. For ZenHub Enterprise, refer to the instructions in https://<zenhub_enterprise_host>/setup/howto/api.

Authentication

All requests to the API need an API token. Generate a token in the API Tokens section of your ZenHub Dashboard. The token is sent in the X-Authentication-Token header. For example, using curl it’d be:

curl -H 'X-Authentication-Token: TOKEN' URL

Alternatively, you can choose to send the token in the URL using the access_token query string attribute. To do so, add ?access_token=TOKEN to any URL.

Notes

• Each user may only have one token, so generating a new token will invalidate previously created tokens.
• For ZenHub Enterprise users, please follow the instructions in https://<zenhub_enterprise_host>/setup/howto/api

API Rate Limit

We allow a maximum of 100 requests per minute to our API. All requests responses include the following headers related to this limitation.

Header	Description
X-RateLimit-Limit	Total number of requests allowed before the reset time
X-RateLimit-Used	Number of requests sent in the current cycle. Will be set to 0 at the reset time.
X-RateLimit-Reset	Time in UTC epoch seconds when the usage gets reset.

To avoid time differences between your computer and our servers, we suggest to use the Date header in the response to know exactly when the limit is reset.

Errors

The ZenHub API can return the following errors:

Status Code	Description
401	The token is not valid. See Authentication.
403	Reached request limit to the API. See API Limits.
404	Not found.

Endpoint Reference

Notes

• repo_id is the ID of the repository, not its full name. For example, the ID of the ZenHubIO/API repository is 47655910. To find out the ID of your repository, use GitHub’s API, or copy it from the URL of the Board (for this repo, the Board URL is https://github.com/ZenHubIO/API#boards?repos=47655910).

Notes

• The endpoint returns the Board’s pipelines, plus the issues contained within each Pipeline. It returns the issue number of each issue, their position in the Board, the is_epic flag (true or false), and its Estimate (if set).
• Even if the issues are returned in the right order, the position can’t be guessed from its index. Note that some issues won’t have position – this is because they have not been prioritized on your Board.
• The Board returned by the endpoint doesn’t include closed issues. To get closed issues for a repository, you can use the GitHub API. Reopened issues might take up to one minute to appear in the correct Pipeline.

Webhooks

You can use our webhooks to fetch or store your ZenHub data, in real time, across services like Slack, Gitter, Spark, HipChat, or something custom!

To set up an integration, head on over to our Dashboard, navigate to your organization, and select the Slack & Integrations tab. From there, you may choose one of the 5 services (Slack, HipChat, Gitter, Spark, or Custom).

For instructions, you'll notice the How to create a webhook link changes dynamically based on the service you select. Simply choose a repository with which to connect, add an optional description, paste your webhook, and click "Add" to save your new integration.

Custom webhooks

Our custom webhook sends a POST request to your webhook for multiple events that occur on your ZenHub board:

  "type": "issue_transfer",
  "github_url": "https://github.com/ZenHubIO/support/issues/618",
  "organization": "ZenHubHQ",
  "repo": "support",
  "user_name": "ZenHubIO",
  "issue_number": "618",
  "issue_title": "ZenHub Change Log",
  "to_pipeline_name": "New Issues",
  "from_pipeline_name": "Discussion"
}

{
  "type": "estimate_set",

  "organization": "ZenHubHQ",
  "repo": "support",
  "user_name": "ZenHubIO",

  "issue_title": "ZenHub Change Log",
  "estimate": "8"
}

{

Issue Reprioritized

{
  "type": "issue_reprioritized",
  "github_url": "https://github.com/ZenHubIO/support/issues/618",
  "organization": "ZenHubHQ",
  "repo": "support",
  "user_name": "ZenHubIO",

  "issue_title": "ZenHub Change Log",

As an example, here's a simple Node/Express app that would be able receive the webhooks (using ngrok):

var express    = require('express');
var http       = require('http');
var bodyParser = require('body-parser');
var app        = express();

http.createServer(app).listen('6000', function() {
 console.log('Listening on 6000');
});

app.use(bodyParser());

app.post('*', function(req, res) {
 console.dir(req.body);
});
