OAuth 2.0 postman automation - oauth-2.0

I am using Postman to automate my rest api call
currently we have changed to this Oauth 2.0 with that I am unable to automate or run the collection .
As I have to manually request an access token and then log in to the UI and then copy the token or use the token .
I was wondering if you have any alternative suggestion as to how we can automate this OAuth 2 token in postman
Thank you

You say you have to log in somewhere first in order to get the token, I guess it is dynamic?
Then use the Pre-request script tab and add the steps for logging in and fecthing the token before each use, if possible. That can then easily be added as a variable and then passed as the Access Token.

How to get access token via rest template call for docusign in springboot app?

I am new to the Docusign integration in springboot gradle application. I am trying to get access token in spring boot app using Rest template but there is no way we do that as per their docs and all. We can only get access token by generating URI using integration key and other things and the we have to copy that uri and paste it to the browser to get code token which we can use to then get JWT access token through API call.
Can we not create JWT access token through rest API calls in application only, please I need all your here...
Thank you in advance!!!
Auth Code Grant requires a browser and user interaction (log in)
JWT authentication does not and you can use this to have your app generate an access token without the user having to open a browser.
However, a one-time consent is required for JWT as well and you can do that manually once and no need to worry about this again.
I would strongly suggest to use the Java quickstart, because not only it gives you working code, it configures everything for you automatically.

generate an access token for a external API to use firebase functions

I am having trouble understanding how to accomplish this. I have Firebase functions running on my application. I am using an external API in which I can configure Webhooks to hit an endpoint on my Firebase functions to perform an action. To make sure that the call comes from this external API, they recommend using an oauth2 flow. Mainly they ask me for:
Provide us (the external API) with an ID and an access token;
these are used to access a URL which provides a bearer token;
this bearer token is then used to access the provided webhook URL until the bearer
token expires after a pre-determined period of time.
And there are 4 input fields:
1. OAuth2 access token url
2. OAuth2 client id
3. OAuth client secret
4. OAuth2 Scope. <---- NOT SURE WHAT THIS ONE MEANS
My question is how do I generate the access token and the client id for this external API?
What value should I put for the oAuth2 scope?
Thanks!
I was able to figure this out using auth0. In one of their documentations, they cleared explained what I was trying to accomplish. Posting here to future reference in case any one needs it.
Thanks all!
reference: https://auth0.com/docs/authorization/flows/client-credentials-flow#learn-more
You can generate the client ID and client secret in the Console > Credentials.
Cloud Functions API oAuth2 scope is https://www.googleapis.com/auth/cloud-platform.

Refresh Bearer Token

I am working in a Power Automate solution which does read data from O365 via Graph API. As, the operation is running more than an hour, the bearer token gets expired.
I have implemented a logic to perform an REST call to regenerate the Bearer Token whenever it fails from the refresh token and ran the failed operation again in a DoUntil loop. But, as I have many calls performed via Graph API , I need to write the logic elsewhere in the Flow.
Pls do let me know whether there are any simple way to regenerate the Bearer Token from the Refresh Token.
Any help would be appreciated!!!
We would recommend start looking at the samples published by Microsoft. Microsoft recommends using MSAL library and MSAL library provides token caching and get fresh token when it's getting close to expiration. For more details on token caching please refer this documentation.
Store the token in a variable and use a parallel branch and get a new token in every 15 or 20 minutes. User the token variable in all API calls

How to expose API to developers securely?

Hi I want to expose API of my web application to the developers so that they can build application on top of my API.
I want to develop it same as twitter does that means I want to build Consumer key,Consumer secret,Request token URL,Authorize URL,Access token URL,Callback URL,Access token,Access token secret.
I know some basics of Oauth that is first we have to generate request token. the request token then gets autherized on successful login by user. Then we can exchange autherized request token with access token.
I want to implement all this in my rails application. But not getting how to start with. I don't have any previous exprience on building and exposing API so any guidelines will be greatly helpful.Thanks in advance
Something like this should help:

Appcelerator. Twitter auth in webview

I am trying to do a Twitter connection using a webview in the excellent Appcelerator Titanium. I know there is a great library from David R out, but I do not want to use a popup and I feel that I need more control over the flow.
My question is: During the authentication flow I need to get an oauth_token which (in my knowledge) is a combination of the consumer key and other values. How can I do this? How can I generate this token so that I can continue the process?
I am of course using Javascript.
Thankful for all input!
It is a multi-step process based on the OAuth 1.0 specs, you can find the details at <http://oauth.net/core/1.0/>
Before doing anything, you will need to register an application with Twitter and they will provide you with a Twitter API Key and a Consumer Token (Key and Secret).
For the next steps, I highly recommend you use OAuthConsumer or some other library, but the steps include generating a proper request to get a "Request Token" from <https://api.twitter.com/oauth/request_token>
then using this Request Token, you need to request the user to authorize your application using <https://api.twitter.com/oauth/authorize?oauth_token=REQUESTTOKENKEY>.
This last step provided you with a Request Verifier allowing your application to make the final request for a permanent Access Token from <https://api.twitter.com/oauth/access_token>.
When you receive the Access Token, you should store a copy somewhere so the user does not have to re-authenticate your application every time (unless that's what you desire). This Access Token does not expire until the user specifically removes the access rights of your application from his Twitter profile. Make sure to store the entire Access Token, meaning storing both the Key and the Secret.
Good luck!
