I'm trying to implement the buy button in my messenger bot, but getting these 2 errors:
{"error":{"message":"(#-1) Send API unexpected internal error","type":"OAuthException","code":-1,"error_subcode":2018012,"fbtrace_id":"BN47MpNqWNN"}}
{"error":{"message":"(#100) Invalid button type","type":"OAuthException","code":100,"error_subcode":2018037,"fbtrace_id":"Agfk\/h+cEta"}}
Any ideas what the issue could be? Where can I look up these error codes? This is the message I'm sending to Facebook's messenger API:
{'message': {'attachment': {'type': 'template', 'payload': {'text': 'Please checkout.', 'template_type': 'button', 'buttons': [{'payment_summary': {'merchant_name': "Peter's Apparel", 'currency': 'USD', 'payment_type': 'FIXED_AMOUNT', 'price_list': [{'amount': '29.99', 'label': 'Subtotal'}, {'amount': '2.47', 'label': 'Taxes'}], 'requested_user_info': ['contact_name'], 'is_test_payment': True}, 'type': 'payment', 'payload': 'DEVELOPER_DEFINED_PAYLOAD', 'title': 'buy'}, {'type': 'postback', 'payload': '{"title": "Confirm Order", "event_value": "", "event_name": "confirm_order"}', 'title': 'Confirm Order'}, {'type': 'postback', 'payload': '{"title": "Add Coupon Code", "event_value": "", "event_name": "add_coupon"}', 'title': 'Add Coupon Code'}]}}}, 'recipient': {'id': '1232211580183568'}}
"The Buy Button only works with the Generic Template and List Template and it must be the first button."
Your template type is 'button'. Try to change your template_type to generic or list. Also, make sure you have access to beta program for payments.
