🚀 Usage

📦 Import the client

from fb_gapi import MessengerClient

🔒 Initialize with your Page Access Token

client = MessengerClient(access_token="YOUR_PAGE_ACCESS_TOKEN")

response = client.send_text(recipient_id="USER_PSID", message_text="Hello, user!")
print(response)

🖼️ Sending an Attachment By URL

image_url = "https://example.com/image.jpg"
response = client.send_remote_attachment(recipient_id="USER_PSID", image_url=image_url)
print(response)

🖼️ Sending a Local Attachment

file_path = "/path/to/image.jpg"
response = client.send_local_attachment(recipient_id="USER_PSID", file_path=file_path)
print(response)

⚠️ Error Handling
