Good morning, it can be implemented through Zapier:
Solution architecture:
1. Facebook Leads → Zapier
2. Zapier Webhook → our Webhook server (for example, on FastAPI / Flask / Node.js / PHP, etc.)
3. Number validation + sending to eChat API

There is also an alternative option.

Hello! I will create a web server that receives a webhook and sends the data obtained from the webhook via API.

Budget: 2000 UAH Deadline: 4 days

Hello! As I understand it, you want to send WhatsApp messages via the Echat API using Zapier and a special webhook.

I will develop a secure webhook that Zapier will send data to via POST method. The webhook will check the incoming lead data, the phone number format, and automatically add the correct country code if it is missing. Then it will use the Echat API to send the WhatsApp message.

For error handling, such as incorrect numbers or WhatsApp being unavailable on the line, I will analyze the Echat API response and return structured logs or retry logic if necessary. If desired, I can deploy this on Vercel, Railway, or any cloud function to avoid server setup.

I have developed several similar API automation schemes and can provide a clean, documented, and testable integration. Here is my profile: Freelancehunt

Do you prefer a ready-made Zapier Webhook + Function application or a separate endpoint that can be used in other tools?

Looking forward to working with you.
Best regards,

Hello!
I can take on the development of the system you need. I have experience working with many APIs, developing web servers, and working with messengers. I will write a server in Python (FastAPI) and webhook, we can connect Zapier and implement sending Echat from the server.
Ready to cooperate!
