Authorization Code Grant Type for cron job

My application is using cronjob. i want o create and update item using new sell API with the help of cron job. but as per the document you must use Authorization Code Grant Type to use inventory scope.

The problem is that with Authorization Code Grant Type a manual sign in is needed.
How can i get a user access token without a signin.

access token new sell api cron

Hi @newtrend ,

You can not a get user access token/Authorization Code Grant Type token without getting the user consent. A user need to Agree on Grant Application Access page to generate a user access token.

REF: https://developer.ebay.com/api-docs/static/oauth-consent-request.htmlYou can also get a user access token through the eBay UI. Please go through the link given below to know more the process.

Hi Team,

@newtrendbeautysupply

I also have same use case and dont know who to proceed. Can you guys please help.

As its a cron job , we dont have any UI to get consent. Is there any other way to use Inventory API?

Thanks

nope. the oath process is via definition a process where the user has to give explicitly his permission. you can use the trading API and the auth'n'auth token, which has a lifetime of one year (if i´m not wrong). but if you need to use the inventory API, there is no other way.

building a UI with a "login with ebay" button is not that difficult. in case u are familiar with PHP: you can try laravel which social login for example.

Hi @michab2003,

Thanks for response. My use case is bit different where i cannot use any UI. My application is like a schedular/poller which run daily in morning and it will read product from specific file location and will put those product on ebay using inventory API.

Is there any way we can get non-expiry consent token so that we can login once and thn use that token for our application?

Thanks

sorry, if you need to work with the inventory api there is no other way than using oauth, and oauth - again - is via definition a user agreement process with a very short token lifetime, because of security. once you have the token, you also get the refresh token which has a much longer lifetime. anyway, there is no way to avoid the "user has to login and agree" process, because that is exactly the definition of oauth. you can hire a developer to get a simple UI.

michab2003:

There are shipping website, seems can remember your loggin information. Once you log into ebay once, those shipping website can retrieve your shipping information forever without loggin. Any clude how they did that?

sure: on their website you login via ebay, they store your auth+refresh token and later on they work with that. there is nothing special, that´s how oauth works.

with rest, you always need oauth, correct. i only wanted to note: depending on what you need it sometimes can be easier to avoid the whole oauth stuff when all calls u need can be done with the trading. most people are totally focused on rest because it´s an easier data structure, but trading still is the most stable (and working) API, ebay has, many don´t (want to) see that ;-))
