We are trying to publish json using pyhton with IMS v3 endpoint.

we are using web type in app authorization and providing client id ,client secret,auth url and access token url in pyhton script.

but post/get method is failing with authorization error 401.

IMS is unaware of what type of client is calling it. So you can use any type of client application, including Python based to call the IMS API. What you need is to represent your Python program as an authorized app in ION API Gateway first. And using the details generated for this app, you can request an access token (/refresh token). And with this access token, you can call the IMS end point.

Did you succeed in getting the access token from your Python script?

Hi Vignesh,

We are able to get access token from pyhton script using client id and client secret using web type authorized app which we have used for postman .

But authorization is failing with that token,could you let us know how to authorize python in ION API Gateway.

from the below options could you let us know which type to select to authorize python in ION API Gateway

Thanks,

For the Authorized App, the common choice with a Python use case is to use Backend Service. Each Type has a purpose specific to use case and security, so the answer is normally a little more planned based on application use.

Hi All,

We have tried with backend service and able to post message to datalake using postman .

We have used same parameters

'ParameterRequest', 'MessagePayload' ,http parameters and backend service(Password Credentials) authentication in python script.

But we are unable to publish the same using python , it is failing with the "multipart message error"

{"status":"FAIL","code":470,"errors":"Multipart message request is invalid. Received ParameterRequest body is not as per specification."} 400

PFb for the python script screenshot.

Could you let us know any additional details to be included in python.

Thanks,

Anish Kulkarni.
