API Scripts

Creating API Scripts

Configurations

  1. Allow Guest: When checked, the API will be publicly accessible without any authentication.

  2. Enable Rate Limit: Enable to apply rate limits to this particular API. For example: “only allow 10 requests per minute”

Script Examples

1. Simple response

frappe.response['message'] = 'pong'


## response:
# {
#  "message": "pong"
# }

2. Using data from the database

expenses = frappe.db.get_all('Expense', pluck='amount') # e.g. [300, 200, 1000]


total_amount = sum(expenses)
frappe.response['total_expenses'] = total_amount


## response:
# {
#  "total_expenses": 1500
# }

3. Using data that came with the request

The request data (JSON and Form) is available in frappe.form_dict as a dictionary of key-value pairs. The below simple API receives first_name and last_name and returns the full_name after joining the two.

first_name = frappe.form_dict.first_name
last_name = frappe.form_dict.last_name


frappe.response['full_name'] = f'{first_name} {last_name}'


## response:
# {
#   "full_name": "John Doe"
# }

4. Updating data in the database

Here is an example of simple API to increment a value in our database:

article_name = frappe.form_dict.article_name
article_doc = frappe.get_doc('Article', article_name)


article_doc.num_likes = article_doc.num_likes + 1
article_doc.save()


frappe.response['message'] = 'success'


## response:
# {
#  "message": "ok"
# }
