Introduction

The Feathery API is organized around REST. Our API has predictable resource-oriented URLs, accepts form-encoded request bodies, returns JSON-encoded responses, and uses standard HTTP response codes, authentication, and verbs.

You can use our API to access and modify your forms, fields, and users. You can leverage our React library for much of th same functionality.

Authentication

Provide your Feathery admin API key to authenticate access. You can get an API key by creating an account.

API keys are environment-specific (production, development, etc.), which allows you to separate real from test data. All API keys have access to the same fields and forms, but users are environment-specific.

Include your API key as a request header that looks like the following:

Authorization: Token <API KEY>

Account

Retrieve Account Information

import requests

url = "https://api.feathery.io/api/account/";
headers = {"Authorization": "Token <API KEY>"}
result = requests.get(url, headers=headers)
print(result.json())

curl "https://api.feathery.io/api/account/" \
    -H "Authorization: Token <API KEY>"

const url = "https://api.feathery.io/api/account/";
const options = { headers: { Authorization: "Token <API KEY>" } };
fetch(url, options)
    .then((response) => response.json())
    .then(result => console.log(result));

The above command outputs JSON structured like this:

{"team": "my-team-name"}

Retrieve your Feathery account information.

HTTP Request

GET https://api.feathery.io/api/account/

Response Parameters

The response will be an object containing the following parameters.

Parameter Type Description
team String The name of your team in Feathery

Documents

Fill a PDF Document Template

import requests

url = "https://api.feathery.io/api/document/fill/";
headers = {"Authorization": "Token <API KEY>"}
data = {"document": <DOCUMENT ID>, "field_values": {<FIELD ID>: <FIELD VALUE>}}
result = requests.post(url, json=headers=headers)
print(result.json())

curl "https://api.feathery.io/api/document/fill/" \
    -X POST \
    -d "{'document': <DOCUMENT ID>, 'field_values': {<FIELD ID>: <FIELD VALUE>}" \
    -H "Authorization: Token <API KEY>" \
    -H "Content-Type: application/json"

const url = "https://api.feathery.io/api/document/fill/";
const data = {document: '<DOCUMENT ID>', field_values: {'<FIELD ID>': '<FIELD VALUE>'}}
const headers = {
    Authorization: "Token <API KEY>",
    "Content-Type": "application/json"
};
const options = {
    headers, 
    method: 'POST',
    body: JSON.stringify(data)
};
fetch(url, options)
    .then((response) => response.json())
    .then(result => console.log(result));

The above command outputs JSON structured like this:

{"file_url": "URL TO FILE"}

Pass in data to fill out a PDF document template that you've uploaded and mapped in your Feathery account.

HTTP Request

POST https://api.feathery.io/api/document/fill/

Response Parameters

The response will be an object containing the following parameters.

Parameter Type Description
file_url String The URL to the filled out PDF document

Forms

Retrieve a Form Schema

import requests

url = "https://api.feathery.io/api/form/my_form/";
headers = {"Authorization": "Token <API KEY>"}
result = requests.get(url, headers=headers)
print(result.json())

curl "https://api.feathery.io/api/form/my_form/" \
    -H "Authorization: Token <API KEY>"

const url = "https://api.feathery.io/api/form/my_form/";
const options = { headers: { Authorization: "Token <API KEY>" } };
fetch(url, options)
    .then((response) => response.json())
    .then(result => console.log(result));

The above command outputs JSON structured like this:
