How to write a Python script to pass data to Appian Web API using username and password

Here is the Python script to pass data to Appian Web API using username and password.

import requests
import json

# Set your Appian environment URL
APPIAN_ENV_URL = "https://my-appian.com"

# Set your Appian login credentials
APPIAN_USERNAME = "my-username"
APPIAN_PASSWORD = "my-password"

# Create a requests session
session = requests.Session()

# Authenticate to Appian
auth_url = APPIAN_ENV_URL + "/suite/api/authentication/login"
auth_headers = {
    "Content-Type": "application/json"
}
auth_payload = {
    "username": APPIAN_USERNAME,
    "password": APPIAN_PASSWORD
}
auth_response = session.post(auth_url, headers=auth_headers, data=json.dumps(auth_payload))

# Get the authentication token
auth_token = auth_response.json()["token"]

# Set the authentication token in the session headers
session.headers.update({"Authorization": "Bearer " + auth_token})

# Set the URL of the Appian web API you want to call
webapi_url = APPIAN_ENV_URL + "/suite/api/webapi/my-webapi"

# Set the data you want to pass to the Appian web API
webapi_payload = {
    "data": "my-data"
}

# Call the Appian web API
webapi_response = session.post(webapi_url, data=json.dumps(webapi_payload))

# Check the response status code
if webapi_response.status_code == 200:
    print("Web API call successful!")
else:
    print("Web API call failed: {}".format(webapi_response.status_code))

# Close the requests session
session.close()

Don’t forget to close the session.
