Hi there, @XhoniT.
To assist you with understanding the retrieval process for company ID during the OAuth Access Token request, It's best to reach out to our Developer team.
Please note that we have a dedicated forum where developers can ask questions and share insights about using the API change log to review changes made to your company ID. I suggest signing up and posting your query in the Intuit Developer Community for direct assistance with this process.
Here's how to post your question:
- Go to this link: https://help.developer.intuit.com/s/.
- Choose QBOunder What do you need help with?
- Pick Ask a Question.
- Sign in with your existing Intuit Developer Account or create a new one.
- Write your concern.
- Click Ask.
If you want a comprehensive understanding of your business flow, please read this article for guidance: Run reports in QuickBooks Online.
