将POST请求发送到我的RESTful API（Python-Flask），但收到GET请求

我正在尝试以包含JSON的POST请求的形式将触发器发送到Zapier Webhook。如果我只是通过本地python脚本发送POST请求，则效果很好。

我想做的是创建一个RESTful API，当调用create-row-in-gs端点时，它会触发Zapier Webhook。

如您所见，我正在向Hasura集群发送POST请求API调用。但是，我没有得到“ 200 OK成功”的响应，而是得到了“ 200 OK成功”，这意味着该请求被视为GET请求而不是POST请求。

test.py

#Python 3 Script to send a POST request containing JSON

import json
import requests

api_url = 'http://app.catercorner16.hasura-app.io/create-row-in-gs'
create_row_data = {'id': '1235','name':'Joel','created-on':'27/01/2018','modified-on':'27/01/2018','desc':'This is Joel!!'}
r = requests.post(url=api_url, data=create_row_data)
print(r.status_code, r.reason, r.text)

server.py（在Hasura群集上运行）

from src import app
from flask import jsonify,request,make_response,url_for,redirect
from json import dumps
from requests import post

url = 'https://hooks.zapier.com/hooks/catch/xxxxx/yyyyy/'

@app.route('/create-row-in-gs', methods=['GET','POST'])
def create_row_in_gs():
    if request.method == 'GET':
        return make_response('failure')
    if request.method == 'POST':
        t_id = request.json['id']
        t_name = request.json['name']
        created_on = request.json['created_on']
        modified_on = request.json['modified_on']
        desc = request.json['desc']

        create_row_data = {'id': str(t_id),'name':str(t_name),'created-on':str(created_on),'modified-on':str(modified_on),'desc':str(desc)}

        response = requests.post(
            url, data=json.dumps(create_row_data),
            headers={'Content-Type': 'application/json'}
        )
        return response

已经为此努力了数周。我究竟做错了什么？将不胜感激。
