REST API

Frappe ships with an HTTP API. There are two parts of this API.

1. Remote Procedure Calls (RPC)
2. REST

1. RPC

A request to an endpoint /api/method/{dotted.path.to.function} will call a whitelisted python function. A function can be whitelisted using the frappe.whitelist decorator.

For example, Add the following to sample_app/__init__.py

@frappe.whitelist(allow_guest=True)
def ping():
    return 'pong'

GET http://frappe.local:8000/api/method/sample_app.ping

Response:

{
  "message": "pong"
}

2. REST

All documents in Frappe are available via a RESTful API with prefix /api/resource/.

Login

To login, you will have to send a POST request to the login method.

POST http://frappe.local:8000/api/method/login

usr=Administrator&pwd=admin

Response:

{
   "full_name": "Administrator",
   "message": "Logged In"
}

Try to make an authenticated request

GET http://frappe.local:8000/api/method/frappe.auth.get_logged_user

Response:

{
   "message": "Administrator"
}

Listing Documents

To list documents, the URL endpoint is /api/resource/{doctype} and the expected HTTP verb is GET.

Response is returned as JSON Object and the listing is an array in with the key data.

GET http://frappe.local:8000/api/resource/Person

Response:

{
   "data": [
      {
         "name": "000000012"
      },
      {
         "name": "000000008"
      }
   ]
}

Fields

By default, only name field is included in the listing, to add more fields, you can pass the fields param to GET request. The param has to be a JSON array.

GET http://frappe.local:8000/api/resource/Person/?fields=["name", "first_name"]

Response:

{
   "data": [
      {
         "first_name": "Jane",
         "name": "000000012"
      },
      {
         "first_name": "John",
         "name": "000000008"
      }
   ]
}

Filters

You can filter the listing using sql conditions by passing them as the filters GET param. Each condition is an array of the format, [{doctype}, {field}, {operator}, {operand}].

Eg, to filter persons with name Jane, pass a param filters=[["Person", "first_name", "=", "Jane"]]

GET http://frappe.local:8000/api/resource/Person/

Response: { "data": [ { "name": "000000012" } ] }

Pagination

All listings are returned paginated by 20 items. To change the page size, you can pass limit_page_length. To request succesive pages, pass limit_start as per your limit_page_length.
