Anvil.http.request POST Error

Anvil Q&A
1

I am new to anvil and trying to make api POST request with anvil.http.request. I am getting http 400 error.
Here is little snippest from my code, which call the POST request.

@anvil.server.callable
def createShipment(orders_list):
    post_url = 'https://apis.tcscourier.com/uat/v1/cod/create-order'
    tcs_username = " Test"
    tcs_password = "tes"
    cost_center = "1123"


    headers = {'x-ibm-client-id': "b997ef40-16e3-428a-b1fa-ddf1d0914edf",
           'content-type': "application/json",
           'accept': "application/json"
           }

    order_status = None
    #tcs_payload = json.dumps(orders_list)
    tcs_payload = orders_list
    try:
      order_status = anvil.http.request(post_url,method="POST",headers=headers,data=tcs_payload)

               
    except anvil.http.HttpError as e:
      order_status = "TCS_Error"
      print(e)
    return order_status

There is nothing wrong either with the api endpoints or POST request payload. The same code works fine in python requests module. I am calling this api from a server module. Can you please tell me what’s I am missing here.

Nothing seems obviously wrong about the above. Have you tried using the requests library from the anvil server module? (instead of anvil.http.request) They may be running a different version than what you have installed locally, but theoretically it should handle the request payloads the same way you’re used to.
