API Reference

Note: a faster API with more consistent response formats can be found at api.inaturalist.org. You will still need to refer to these docs for obtaining an OAuth access token.

The iNat API is a set of REST endpoints that can be used to read data from iNat and write data back on the behalf of users. Data can be retrieved in different formats by appending .[format] to the endpoint, e.g. /observations.json to retrieve observations as JSON. Read-only endpoints generally do not require authentication, but if you want to access data like unobscured coordinates on behalf of users or write data to iNat, you will need to make authenticated requests (see below).

Note that endpoints that receive binary data must have the Content-Type: multipart-formdata header and parts that are not binary should be simple form data, even if you're requesting JSON data.

Authentication

iNaturalist is an OAuth2 provider and supports the Authorization Code, Resource Owner Password Credentials, and Proof Key for Code Exchange (PKCE) flows, as well as some custom auth flows for 3rd party authentication. Methods marked Auth required require authentication via one of the aforementioned methods. Please make sure to use https://www.inaturalist.org as the base URL for authorization flows and for authenticated requests to ensure passwords and access tokens are encrypted. Unfortunately we must maintain the vanilla http endpoints for backward compatability, but all future API users should make requests with SSL. Note that many PUT and DELETE methods also check for ownership and will fail if you try to use them when not authenticated as the user who owns the associated resources.

Auth Examples

Before you make any authenticated requests, you'll need to create an iNat application. The redirect_uri should be functioning URL to which users will be redirected upon successfully authorizing your app with access to the user's iNat data.

There are plenty of language-specific OAuth2 libraries out there, so find one you like or get familiar enough with OAuth2 to construct requests and manage redirect flows yourself. The following examples use Ruby's oauth2 gem.

Authorization Code Flow

This is what you'll want to use if your app is a web app, and/or you're sure you're users can open a web browser for auth *and* you can store your client secret in a secure fashion. The rough outline is you redirect your user to iNat, the user is offered the choice to authorize your app with access to their iNat data, and if they agree, they are redirected to the redirect_uri you specified with an access_token in the params.

Proof Key for Code Exchange Flow

This is a variation on the Authorization Code Flow for use in situations where you cannot store your client secret securely, e.g. in a client-side Javascript application or a mobile application that could be decompiled. Instead of providing a secret to identify itself, the client provides a hashed, single-use "code verifier" when requesting an authorization code. When the client requests an access token it must provide the unhashed code verifier to verify that it is the same client that requested the authorization code. More details at the IETF, but the Doorkeeper docs might be easier to read.

Resource Owner Password Credentials Flow

Retrieve an access token based on the user's iNat username and password. This is more for desktop and mobile apps, or any situation where you can store a user's password and they have reason to trust you, i.e. not for web.

Assertion Flow

This is roughly based on http://tools.ietf.org/html/draft-ietf-oauth-assertions-01#section-6.3 and used to retrieve an access token for a user based on a 3rd party access token from Facebook or Google. It assumes the user is already a member of iNat or wants to be, and uses the 3rd party token to sign them up and / or authenticate them. It returns an access token without the authorization step. This method is only available to partners we're working with directly.

Endpoints

All of these endpoints should use https://www.inaturalist.org as the base URL, particularly endpoints that require auth.

POST /comments

Auth required

Create comments. Comments are automatically associated with the signed in user.

GET /observations

Primary endpoint for retrieving observations. If you're looking for pagination info, check the X headers in the response. You should see X-Total-Entries, X-Page, and X-Per-Page. JSON and ATOM responses are what you'd expect, but DwC is Simple Darwin Core, an XML schema for biodiversity data. iNat uses JSON responses internally quite a bit, so it will probably always be the most information-rich. The widget response is a JS snippet that inserts HTML. It should be used with a script tag, e.g.

<script
src="http://www.inaturalist.org/observations.widget"></script>
. Note that while this endpoint doesn't require authentication under normal circumstances, it WILL require it when you request pages higher than 100. If you're going to scrape us, we want to know who you are.

Formats: atom, csv, dwc, json, kml, widget

Params

POST /observations

Auth required

Primary endpoint for creating observations. POST params can be specified for a single observation (e.g. observation[species_guess]) or as multiple to add a multiple observations at a time (e.g. observations[0][species_guess]).

Formats: html, json

Params

observation[species_guess]
Equivalent of the "What did you see?" field on the observation form, this is the name of the organism observed. If the taxon ID is absent, iNat will try to choose a single taxon based on this string, but it may fail if there's some taxonomic amgiguity.
observation[taxon_id]
ID of the taxon to associate with this observation. An identification for this taxon will automatically be added for the user."
valid iNat taxon ID
observation[observed_on_string]
Text representation of the date/time of the observation.
iNat is pretty flexible in the dates it can parse out of this value. Here are some examples
  • 2 days ago
  • January 21st, 2010
  • 2012-01-05
  • October 30, 2008 10:31PM
  • 2011-12-23T11:52:06-0500
  • July 9, 2012 7:52:39 AM ACST
  • September 27, 2012 8:09:50 AM GMT+01:00
The only constraint is that dates may not be in the future. Time zone will default to the user's default time zone if not specified.
observation[time_zone]
Time zone the observation was made in.

GET /observations/:id

Retrieve information about an observation

Formats: json

PUT /observations/:id

Auth required

Update a single observation. Not that since most HTTP clients do not support PUT requests, you can fake it be specifying a _method param. This basically takes all the same params as POST /observations using the observation[] params. Here we're documenting some additional params for updating.

Params

_method
HTTP method to use if your client doesn't support PUT
put
ignore_photos
Ignore the absence of photo params. iNat assumes you are submitting data about existing photos with each request to update an observation, since that's how the HTML form works. If they're absent, iNat assumes the user wanted to remove those photos. Setting this param will override this behavior and leave any existing photos in place.
0 | 1
observation[observation_field_values_attributes][order]
Again, pretty much the same as POST /observations, but you can update existing ObservationFieldValues by including their IDs, and remove them using the _delete param.
ObservationFieldValue attributes. You could update an ObservationFieldValue with an ID of 1 with observation[observation_field_values_attributes][0][id]=1&observation[observation_field_values_attributes][0][value]=foo. You could delete the same with observation[observation_field_values_attributes][0][id]=1&observation[observation_field_values_attributes][0][_delete]=true

DELETE /observations/:id

Auth required

Delete an observation. Authenticated user must own the observation. No response body, just a 200 SUCCESS.

Formats: json

Example

Request
/observations/297867.json
Response

POST /observations/:id/quality/:metric

Auth required

Vote on quality metrics for an observation. These allow any user to vote on aspects of any observation's data quality.

Formats: json

Params

id
ID of observation being voted on.
Observation ID integer
metric
Aspect of data quality being voted on. Possible values are wild (whether or not observation is of a wild vs. captive / cultivated organism), location (whether or not coordinates seem accurate), date (whether or not date seem accurate).
wild | location | date
agree
Whether the user is voting yes or no on this metric, e.g. if the metric is wild and agree is false, the user is voting that the observation is not of a wild organism, i.e. it is captive or cultivated.
true | false

DELETE /observations/:id/quality/:metric

Auth required

Remove the user's vote on a quality metric. Not the same as voting no. Same id and metric params as POST /observations/:id/quality/:metric

Formats: json

PUT /observations/:id/viewed_updates

Mark updates associated with this observation (e.g. new comment notifications) as viewed. Response should be NO CONTENT.

Formats: json

GET /observations/:username

Mostly the same as /observations except filtered by a username.

Params

updated_since
Behaves the same as it does with GET /observations, with the addition of an extra HTTP header in the response. Since this is mainly used for syncing with 3rd party services and devices, this will also include an HTTP header called X-Deleted-Observations that contains a comma- separated list of observation IDs that have been deleted.
ISO 8601 datetime, e.g. 2013-10-09T13:40:13-07:00

GET /observations/project/:id

Just like /observations except filtered by a project. :id can be a project ID or slug. CSV response will return some extra project-specific daa.

Formats: atom, csv, json, kml, widget

GET /observations/taxon_stats

Retrieve some stats about taxa within a range of observations. species_counts are counts of observations identified to the species level or lower. total is the total number of taxa of all ranks. You must include the on, d1/d2, place_id, user_id, or projects params or this endpoint will just return blank results. This endpoint should accept all the params available for /observations.

Formats: json

GET /observation_fields

List / search observation fields. ObservationFields are basically typed data fields that users can attach to observation.

Formats: json

Params

q
Search query
Any string
page
any integer

POST /observation_field_values

Auth required

Create a new observation field value. ObservationFields are basically typed data fields that users can attach to observation. ObservationFieldValues are the instaces of those fields. Note that you can also create these with nested params in POST /observations.

Formats: json

Params

observation_field_value[observation_id]
ID of the observation receiving this observation field value.
Valid iNat observation ID
observation_field_value[observation_field_id]
ID of the observation field for this observation field value.
Valid iNat observation field ID
observation_field_value[value]
Value for the observation field value.
Any string, but check the field's allowed values.

PUT /observation_field_values/:id

Auth required

Update an observation field value. Parameters are the same as POST /observation_field_values

Formats: json

DELETE /observation_field_values/:id

Auth required

Delete observation field value.

Formats: json

POST /observation_photos

Auth required

Add photos to observations. This is only for iNat-hosted photos. For adding photos hosted on other services, see POST /observations and PUT /observations/:id. This should be a multipart request.

Params

observation_photo[observation_id]
ID of the observation receiving this photo. This part of the multipart should appear as regular form data, not JSON, so Content-Disposition: form-data; and no Content-Type
Valid iNat observation ID
file
The photo data.
Multipart photo data

GET /places

Retrieve information about places.

Formats: json

Params

page
any integer
1
per_page
1 to 200
30
ancestor_id
Filter places by an ancestor place based on place hierarchy. If you wanted to view all places that are a part of California, you would set ancestor_id=14.
Place ID integer
place_type
Type of place to retrieve
Aggregate | Airport | Colloquial | Continent | Country | County | Drainage | Estate | Historical County | Historical State | Historical Town | Intersection | Island | Land Feature | Local Administrative Area | Miscellaneous | Nationality | Open Space | Point of Interest | Region | State | Street | Street | Street Segment | Supername | Town | Undefined | Zone
taxon
Retrieve places with this taxon on their check lists. Can be specified as an ID or a name, though vernacular names may yield unpredictable results. Note that this gets a bit weird for continents, since they don't have check lists: continents will not be returned *unless* place_type=continent.
Taxon ID or name
establishment_means
Filter taxon-specific place searches by how the taxon was established there, e.g. if it is native, introduced, invasive, etc. Note: searches for "native" will return places where the taxon is "native" or "endemic," and searches for "introduced" will return places where the taxon is "introduced," "naturalised," "invasive," or "managed."
native | endemic | introduced | naturalised | invasive | managed
latitude
Retrieve places that contain this lat/lon combination. This will only return places with boundaries defined.
Decimal latitude, e.g. 12.345
longitude
See latitude
Decimal longitude, e.g. 12.345
