I am new to wso2 api, I have created api using api publisher,I am generated api client_id and client_secrete,It works fine fine wso2 api rest client,my question is How to call rest service using restful client?(to use wso2 client_id and client_secret)
Thanks,
Ram
Generally we don't use client_id and client_secret for calling REST APIs. Those are used to generate an OAuth token to invoke REST APIs. What you have to do is get the generated OAuth token in API Store and invoke the API. For that you need to set "Authorization" header in your HTTP request as below.
"Authorization" : "Bearer Generated_OAuth_Token"
This is just a basic OAuth scenario. I strongly recommend you to research more on OAuth protocol.

We're going to expose a custom built API (.NET) through Azure API Management. We want to conform to well-known standards where ever possible, so we don't surprise our API consumers. The API is secured through an API key which users generate from APIM's Developer Portal.
My understanding is that the Authorization header should be used for authentication and authorization purposes.
https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Authorization
But strangely, API-Key is not included as an authentication scheme.
https://www.iana.org/assignments/http-authschemes/http-authschemes.xhtml#authschemes
Should API consumers use an authorization header to authenticate?
E.g. Authorization: API-Key xxx-xxx
Or a custom header.
E.g. my-key:xxx-xxx
Technically, you shouldn't need any API-key if you have a token in the authorization header. I assume API-key/client and secret key are already used to generate a token. When the client sends token via an authorization header, the API owner validates your token and returns a response.
I am trying to make an API request against a Dynamics 365 API account using Postman. I have the following credentials but I do not know what headers to use to authenticate.
I have the following ...
Consumer Key
Consumer Secret
Redirect Uri
Authorize Redirect URL
HTTP Method = POST
Access Token Service Endpoint
What headers do I need to set in Postman to get access to the API?
I have read articles and seen some examples but they all have different data than I do. For example in the screen capture below there is a username and password in addition to a Consumer Key (client_id) and Consumer Secret (client_secret).
I do understand that I need to obtain a Bearer token first before making the API call. It is obtaining this token that is confusing me.
Simply follow this documentation to setup the Postman for Dynamics web API, even the ready-made clientid = 51f81489-12ee-4a9e-aaae-a2591f45987d will work for any CRM online instance for testing purpose. You can use your customer provided clientid as well.
url should be https://crmdev.crm.dynamics.com
authurl should be https://login.microsoftonline.com/common/oauth2/authorize?resource={{url}}
First create an environment in Postman:
Use OAuth 2.0 in Authorization tab, and Get New Access Token.
(I am pretty new in grpc and golang)
I have a website that uses grpc-web package to communicate to a banckend grpc api server in golang. I need user authentication with github. But I am having difficulties in understanding how to use oauth2 token based authentication in grpc. I will appreciate if you can share your idea.
It looks like the way to use OAuth2 with grpc-web is to add the header to the metadata object which is the second argument to each rpc call.
my_grpc_web_client.MyMethod(myRequestProto, {Authorization: "Bearer <token>"});

I want to consume Magento Rest API using Talend, I already generated oauth_token & oauth_token_secret but when i am using it with tRestClient component it is returning as 403 error code any one suggest how to configure it?
I Don't think so there is option by which you can integrate magento rest api with Talend.
Authentication
Magento REST API uses 3-legged OAuth 1.0a protocol to authenticate the application to access the Magento service.
So For each time I think you have to authorize the application.
I think you can use Soap API or XML RPC for this.
I'm implementing a RESTful web service using ASP.Net Web Api and Backbone.js at client side. What will the best way to authenticate user?
You are building SPA then it is recommend to use Token Based Authentication not Cookies, once you obtain the access token from the Auth server (Web API) you need to store it in html5 local storage then with each subsequent request to a protected resource you need to send this access token in the "Authorization" header using bearer scheme.
I've compiled detailed post about this but it uses Angular, so it will be very close to backbone.js
