How can I get Authorization Code for API programmatically?

[muhatay-64]

I have recently joined eBay and signed up a developer account. I want to integrate eBay APIs to my PHP Laravel Website. I need access token to call different APIs and to get an access token first I need to get an authorization code which will be provided in next API call to get an access code. I see there is an option to get authorization code where Application Keys are, by creating a user and giving consent to login to my application, which returns authorization code. But I want to do that programmatically as I am a developer and I want some way like an API where I can get authorization code. I did not find it in documentation. I don't know if I am missing something here. Is there some Postman Collection with these calls?

There are OAuth client libraries for Android, C#, Java, Node.js and Python but none can be found for PHP.

Following is the link of doc I am following:

No, it's not possible to generate the authorization code grant token without obtaining user consent. You must secure the user's consent at least once because generating a user access token is contingent upon it.

For further details, please consult the API documentation here:

The authorization code grant process yields a refresh_token, which has a lengthy lifespan. You can utilize this token to renew an expired user access token, eliminating the need to repeatedly seek the user's consent for a new token. Simply store the refresh_token for future use.

For a comprehensive understanding, delve into the Refresh Token API documentation:
