3.2. Implementing Server-Side Code for Event Transmission

Implementing server-side code is the heart of Pinterest CAPI implementation, where you’ll structure and send events via secure POST requests. Choose your backend language—Python with requests library or Node.js with axios—and install necessary dependencies. Define event objects with required fields: ‘eventname’ (e.g., ‘purchase’), ‘eventtime’ (current Unix timestamp), ‘actionsource’ (‘website’), and ‘userdata’ with hashed values. Include ‘custom_data’ for details like order value and currency to enable ROAS optimization.

Here’s a practical Python example for event transmission:

import requests
import hashlib
import time
import uuid

def hash_data(data):
return hashlib.sha256(data.lower().encode()).hexdigest()

def sendpinterestevent(token, accountid, eventname, useremail, value, currency):
url = f”https://api.pinterest.com/v5/adaccounts/{accountid}/events”
eventid = str(uuid.uuid4())
eventtime = int(time.time())
userdata = {
’em’: hashdata(useremail),
‘eventid’: eventid # For deduplication
}
eventpayload = {
‘eventname’: eventname,
‘eventtime’: eventtime,
‘actionsource’: ‘website’,
‘userdata’: userdata,
‘customdata’: {‘value’: value, ‘currency’: currency},
‘eventid’: eventid
}
headers = {
‘Authorization’: f’Bearer {token}’,
‘Content-Type’: ‘application/json’
}
payload = {‘data’: [eventpayload]}
response = requests.post(url, json=payload, headers=headers)
if response.status_code == 200:
print(‘Event sent successfully’)
else:
print(f’Error: {response.json()}’)
return response.json()

Usage example

sendpinterestevent(‘YOURTOKEN’, ‘YOURACCOUNT_ID’, ‘purchase’, ‘[email protected]’, 100.0, ‘USD’)

This code handles hashing for privacy compliance and includes error handling for 4xx/5xx responses. For Node.js, adapt using the crypto module and fetch API. Integrate this function into webhooks, triggering on user actions like form submissions. To optimize, batch multiple events in the ‘data’ array, up to 100 per request, reducing API calls and improving efficiency during peaks.

Test incrementally: start with single events, verify in the Events Manager, then scale to production. Add logging for debugging and retries with exponential backoff for transient failures.
