I need help to evaluate weather i am doing it right or not, the scenario is an 3rd party application is sending an webhook request after a successful payment but the problem is that sometimes this application may send the same notification more than once.so it is recommended to ensure that implementation of the webhook is idempotent.so steps that i am implementing for this are if signature is correct (assume it is corect),Find orders record in the database using orderId in the request params.

AWS S3 static file access works on local but not production
I have setup a AWS S3 bucket for both my static and media files but it currently only works on local host but not when I try on gunicorn or when I deploy to Heroku. When I take a look at the network information on local host I can see the network is attempting to access the files from "https://mybucketname.s3.amazonaws.com/static/image.png". However, when I try this on gunicorn or heroku it is attempting to serve the files from "https://none.s3.amazonaws.com/static/image.png".

Can you combine Django Simple JWT with Oauth2 Azure?
I am using the simple JWT Django authentication module in a Django Rest APP. I need to implement Oauth2 Azure login protocol. As my frontend(react.js) is already configured with access and refresh token generated by the simple JWT, could I use the simple JWT to generate access and refresh tokens and some oauth2 module for the authentication?

How to Use Django Rest Framework to Call API with Javascript Files
I've done a few projects in Django before but I've never done one using the Django Rest framework, and it's my first time using an API. I'm trying to learn how to use it, and the class I'm taking makes it mandatory to create the project in Django, and use Javascript as the front end. 2 Questions: I'd like to call the API within the Javascript code. Can this be done using the Django Rest framework? I'm also having trouble figuring out how to show my html file with this url setup. Any help is appreciated. Currently when I go to http://127.0.0.1:8000/ I just get the API Root page. So far most tutorials I see, are just for calling the API in a Django view. They don't talk about how to use Javascript files to call the API also with the Django Rest Framework, and show the html file to the user. If you can point me to documentation or explain a bit more I'd really appreciate it! views.py - currently the home view is not showing or doing anything, but I want this to show to the user. class LocationViewSet(viewsets.ModelViewSet): queryset = Location.objects.all() serializer_class = LocationSerializer() def home(request): return …
