# <a name="main-title"></a> Idealist Listings API documentation
## <a name="target-audience"></a> Target Audience
This documentation is aimed at software developers wishing to implement programmatic fetching of listings posted on Idealist.org.
## <a name="overview"></a> Overview
Idealist.org provides the Listings API to consume listings posted on Idealist.org.
The API is a JSON-based REST API. You'll need an API token.
## <a name="support"></a> Support
You must contact the Idealist support staff to obtain an API token: <support@idealist.org>.
For technical questions regarding the API during the implementation phase, contact <api@idealist.org>.
For support afterward, contact <support@idealist.org>.
## <a name="quickstart"></a> Quickstart
Here's an example of Python code that would fetch all the full-time jobs. It's going to
fetch jobs from `https://www.idealist.org/api/v1/listings/jobs` and also get job details
`https://www.idealist.org/api/v1/listings/jobs/{job_id}`.
```python
import requests
import time
API_TOKEN = "your token here"
headers = {"Accept": "application/json"}
# start by discovering all the job IDs
job_ids = set()
url = "https://www.idealist.org/api/v1/listings/jobs"
has_more = True
ttl = 200 # to avoid looping forever in case something is wrong in the code
while has_more and ttl > 0:
ttl -= 1
print("GET", url)
response = requests.get(url, headers=headers, auth=(API_TOKEN, ""))
assert response.status_code == 200
data = response.json()
print("Received", len(data["jobs"]), "jobs")
for job in data["jobs"]:
job_ids.add(job["id"])
has_more = data["hasMore"]
since = data["jobs"][-1]["updated"]
url = f"https://www.idealist.org/api/v1/listings/jobs?since={since}"
time.sleep(1) # politeness
print("Discovered", len(job_ids), "jobs")
MOST_RECENT_UPDATE = data["jobs"][-1]["updated"] # store that value somewhere for later
print("Most recent update", MOST_RECENT_UPDATE)
# now that we know all the job IDs, we can fetch more details about the jobs
jobs = []
for job_id in job_ids:
url = f"https://www.idealist.org/api/v1/listings/jobs/{job_id}"
print("GET", url)
response = requests.get(url, headers=headers, auth=(API_TOKEN, ""))
if response.status_code == 200: # job may have been unpublished since we got the ID
jobs.append(response.json()["job"])
time.sleep(1) # politeness
```
Then, a few moments later (daily, hourly, etc.), we can fetch only the jobs that were
updated since last time we queried the API:
```python
since = MOST_RECENT_UPDATE # get that value from where you stored it above
job_ids = set()
url = f"https://www.idealist.org/api/v1/listings/jobs?since={since}"
has_more = True
ttl = 200 # to avoid looping forever in case something is wrong in the code
while has_more and ttl > 0:
ttl -= 1
print("GET", url)
response = requests.get(url, headers=headers, auth=(API_TOKEN, ""))
assert response.status_code == 200
data = response.json()
print("Received", len(data["jobs"]), "jobs")
for job in data["jobs"]:
job_ids.add(job["id"])
has_more = data["hasMore"]
since = data["jobs"][-1]["updated"]
url = f"https://www.idealist.org/api/v1/listings/jobs?since={since}"
time.sleep(1) # politeness
# job_ids should contain only a few jobs instead of a few thousands
print("Discovered", len(job_ids), "jobs")
```
## <a name="authentication"></a> Authentication
To authenticate all API endpoint requests, you must obtain a production API token from the Idealist support staff -- <support@idealist.org>
You must use the API token as the `username` for Basic HTTP authentication. Use an empty string for the `password`.
Most HTTP libraries come with Basic authentication. For example, using the Python library `requests` (<http://python-requests.org>):
```python
import requests
API_TOKEN = "9e11d62224ab48c79432fae431397620"
url = "https://www.idealist.org/api/v1/listings/jobs"
headers = {
"Accept": "application/json",
}
response = requests.get(url, auth=(API_TOKEN, ""), headers=headers)
jobs = response.json()["jobs"]
print(jobs)
```
For more information: <https://en.wikipedia.org/wiki/Basic_access_authentication>.
## <a name="rate-limiting"></a> Throttling / Rate Limiting
There's currently no implementation of any rate limiting. However, we expect API users
to respect our resources and not do any requests in parallel.
It's also encouraged to wait at least a few milliseconds (250ms is great) between requests.
Lastly, the API is provided with the hope that clients will store the value of `since` they should use next time they fetch listings, and not fetch all the listings from scratch every time they want to get the latest listings.
## <a name="unpublished-listings"></a> Unpublished Listings
In the [Quickstart](#quickstart) example above, the listings returned were only the published ones.
If you need to know when listings are unpublished, you can add the parameter `includeUnpublished=true` when fetching the list of listings. Note that this parameter is only taken into account when also using the parameter `since`.
For example:
```python
since = MOST_RECENT_UPDATE # get that value from where you stored it above
job_ids = set()
unpublished_job_ids = set()
url = f"https://www.idealist.org/api/v1/listings/jobs?includeUnpublished=true&since={since}"
has_more = True
ttl = 200 # to avoid looping forever in case something is wrong in the code
while has_more and ttl > 0:
ttl -= 1
print("GET", url)
response = requests.get(url, headers=headers, auth=(API_TOKEN, ""))
assert response.status_code == 200
data = response.json()
print("Received", len(data["jobs"]), "jobs")
for job in data["jobs"]:
if job["isPublished"]:
job_ids.add(job["id"])
else:
unpublished_job_ids.add(job["id"])
has_more = data["hasMore"]
since = data["jobs"][-1]["updated"]
url = f"https://www.idealist.org/api/v1/listings/jobs?since={since}"
time.sleep(1) # politeness
# job_ids should contain only a few jobs instead of a few thousands
print("Discovered", len(job_ids), "jobs")
print(len(unpublished_job_ids), "jobs are unpublished")
```
Here's a sample response:
```json
{
"jobs": [{
"id": "2f1cf635d6b14c9587a83a7375ea1412",
"firstPublished": "2019-06-23T18:02:07.212112Z",
"updated": "2019-06-23T18:02:07.269921Z",
"name": "Executive Director",
"url": {
"en": "https://www.idealist.org/en/nonprofit-job/...",
"es": "https://www.idealist.org/es/ong-empleo/...",
"pt": "https://www.idealist.org/pt/ong-emprego/..."
},
"isPublished": true
}, {
"id": "56a98590617e458c967e7b3633d40302",
"firstPublished": "2019-06-23T18:02:09.093284Z",
"updated": "2019-06-23T18:02:08.283617Z",
"name": null,
"url": {
"en": null,
"es": null,
"pt": null
},
"isPublished": false
},
...
],
"hasMore": true
}
```
## <a name="endpoints"></a> API Reference - Endpoints
All endpoints are hosted on `https://www.idealist.org`. For example, when the docs show
`GET /api/v1/listings/jobs`, it means you should do a `GET` request to
`https://www.idealist.org/api/v1/listings/jobs`.
### <a name="jobs"></a> Jobs
`GET /api/v1/listings/jobs`
Sample response:
```json
{
"jobs": [{
"id": "2f1cf635d6b14c9587a83a7375ea1412",
"firstPublished": "2019-06-23T18:02:07.212112Z",
"updated": "2019-06-23T18:02:07.269921Z",
"name": "Executive Director",
"url": {
"en": "https://www.idealist.org/en/nonprofit-job/...",
"es": "https://www.idealist.org/es/ong-empleo/...",
"pt": "https://www.idealist.org/pt/ong-emprego/..."
},
"isPublished": true
},
...
],
"hasMore": true
}
```
It returns up to 100 jobs, ordered by oldest updated first.
To page through all the jobs, you can pass `since` in the URL like so:
`GET /api/v1/listings/jobs?since=2019-06-23T18:02:07.269921Z`
using the last job's `updated` value. For example, in Python:
```python
import requests
import time
job_ids = set()
API_TOKEN = "your token here"
url = "https://www.idealist.org/api/v1/listings/jobs"
headers = {"Accept": "application/json"}
has_more = True
ttl = 200 # to avoid looping forever in case something is wrong in the code
while has_more and ttl > 0:
ttl -= 1
response = requests.get(url, headers=headers, auth=(API_TOKEN, ""))
data = response.json()
for job in data["jobs"]:
job_ids.add(job["id"])
has_more = data["hasMore"]
since = data["jobs"][-1]["updated"]
url = f"https://www.idealist.org/api/v1/listings/jobs?since={since}"
time.sleep(1) # politeness
```
Note that `since` is inclusive, meaning that you should expect to get the last job again as the first job in the next request.
`GET /api/v1/listings/jobs`
A request with many parameters looks like this:
`GET /api/v1/listings/jobs?since=2019-06-23T18:02:07.269921Z`
### <a name="job-details"></a> Job Details
