I need to publish messages to GCP Pub/Sub with a POST request as the platform I'm using (Zoho) does not allow for any of the GCP libraries. I'm not sure how to make the request in a simple way, as the normal authentication system seems complex.
Is there an easy way to publish a message using, e.g., an API key?
Alternatively is there a simple way to create an API endpoint within GCP that I can then forward data on to the messaging system?
I have used the python client to publish to Pub/Sub, but cannot make POST requests because of the authentication issues.
Both of your questions will have the same answer, yes, and Google Cloud Endpoints is your way to go here.
With Google Cloud Endpoints you can create a custom endpoint and use API keys to authenticate the requests that are being done. There's a really good how-to guide from medium you can follow in order to set up your endpoint and your Pub/Sub push subscription.
More information about creating push subscriptions can be found in the public documentation.

An ex-employee planned a Microservice Architecture which is being implemented now. I've few question regarding the design and I'd highly appreciate your feedbacks.
Explanation
Dematerialized UI has a matching dematerialized API.
Dematerailized API validates the user and generates token via SSO Library.
Flight API does the I/O validation & validate the request via validate request microservice
Flight API calls Booking API to get some bookings based on the UserId
Flight API calls Print Booking API to generate Messages using Generate Message Microservice
Print Booking API must call Data Access API to get data and then call Generate PDF microservices.
Data Access API calls the database for data.

Questions
Should I be using ocelot in DMZ.API.csproj, Flight API and Print Booking API.
Is my project structure a Microservice way of development
Should I continue to use ASP.NET Core Web API with .NET 6 for Dematerialized API in orange, Function API in blue and Microservice in purple projects.
For validation, since the SSO is passed from Dematerialized UI what if the token expires while CRUD operations
is already performed for some stages [rolling back changes is a hassle].
Should each API access to an identidy server and validate the user passed and generate its own token for its
services in purple.
Thank you in advance.
The core question is if you really need all those services and if you perhaps are making things too complicated. I think the important thing is to really consider and really make sure you justify why you want to go through this route.
If you do synchronous API calls between the services, that creates coupling and in the long run a distributed monolith.
For question #4, you typically use one access token for the user to access the public service, and then you use a different set of internal tokens (machine-to-machine also called client credentials in OpenID Connect parlor) between services that have a totally different lifetime.
q1: ocelot is an API GATEWAY which is the entry point for your requests. so it should be the first layer/service meet by user request in front of your services and it forwards the request to the service according to its configuration. so it is lay in the front for all services you have. some arch provide another api gateway for different reasons like specific api gateway for mobiles request for example.
q2: as looking separate services (i cant understand function api but i assume they are services also ) yes but the microservices development is not just about separating things, its about design and identifying the services from business context (Domain Driven Design).its very challenging to identify services and their size and the way they are communicate to each other (asynchronous communication and synchronous communication).
q3: microservices is not about languages and frameworks.one of benefits of microservices architecture is its not language or framework dependent. the may be multiple languages used in microservices. choosing languages it depends on organization policy or your own reasons. if you are .net developer then go for .net.
q4: all the services are registered with identity server and they validate the given token by it. the identity server generate token (there may be multiple tokens) with scopes . the request from identified users always has the token in the headers and the services validate incoming token by referring identity server. this tokens has lifetime and also identity server generates refresh tokens in case of expiry of current token. please look at Oauth docs and rfc. also this https://www.youtube.com/watch?v=Fhfvbl_KbWo&list=PLOeFnOV9YBa7dnrjpOG6lMpcyd7Wn7E8V may helped. you can skip the basic topics. i learned a lot from this series.
I have a requirement to download attachments from Jira during event triggers and upload back to other supporting tool. For this purpose, started using WebHooks, during event trigger, json values will get passed thru post call. I have found Jira rest api also to get attachment download link to use it in webhooks. But this rest api requires valid authentication. I can't use basic login details to hard code in the script for downloading through URL.
How can I authorize this URL for getting the attachment. I heard that, we can establish OAuth and for this I need to enable application linking. At this stage, I am not sure how can I link the WebHook URL as an application. Current Hook is not a complete application it just accepts json as post and parses through it.
Need your support how to enable this OAuth and how to create that app. I am newbie to this WebHooks and OAuth concepts. so bare me for the generic queries .. :)
If there are any other possible solutions for my requirement are also welcomed.
Thank you..
Where do the Slack default avatars come from? Is it their own service or a 3rd party one?
In either case, is there a possibility for others to use the avatar creation service / system e.g. via the slack API?
I asked Slack directly, and they don't currently offer this in their API:
We don't have an API method or service for it, so there isn't a way to do this, sorry!
They've heard the suggestion, though.
I'm still new to GAE, and I would like to have more wisdom about couple of things.
I searched in documentation, but I think I'm just too stupid to understand some things from documentation.
How can I combine Google Cloud SQL with endpoints? Is there such possibility?
How can I use endpoints to upload videos to google platform?
You should be able to use anything you can do on a non cloud endpoints api to cloud endpoints like google cloud sql. But since it's on preview you might encounter bugs/changes when it goes out of preview. You should create a Cloud SQL tests models on regular app engine app then try to use it on cloud endpoints, so you can minimize debugging for errors.
https://developers.google.com/appengine/docs/python/cloud-sql/
You will need to use a blobstore api:
https://developers.google.com/appengine/docs/python/blobstore/
on your endpoints have a method that creates the upload url and use that to upload from your app then on the uploadHandler it will trigger once the whole file has been uploaded, process your blobInfo key store it appropriately.
I'm trying to create a redistributable web application that will integrate with Google Analytics through the Google Reporting API. Customer will install the application on their server.
I'm following this tutorial (I'm using PHP, but I believe this is not of importance for my question)
https://developers.google.com/analytics/resources/tutorials/hello-analytics-api
This works fine. No issues there.
However I can't figure out one missing element:
The tutorial starts with sending me to the Google APIs console where I have to create and configure a new API project and create and configure a client ID.
That's a lot of work that requires fairly technical knowledge (redirect url, selecting correct API, error-prone copy-and-pasting, etc.)
So my questions:
Is there an API so I can programmatically set this up for my user?
If that's not possible, is there a more user-friendly way to obtain Analytics reporting that is future-proof? (I noticed they are currently deprecating a few older APIs)
Unfortunately that's AFAIK not possible.
You could go one of the following ways:
Move client_id and client_secret to some configuration file and help your customer with deployment.
Show a one-time setup wizard for your app and guide your customer step-by-step. There you can at least provide him with the right callback URLs.
Regard your application as "installed application" and instrument curl or something similar for sending the requests.
