Thanks for reaching out to us, amarp_chetu. 

I can refer you to the right department that can help you in building the source code. 

We have a separate forum called Intuit Developers, where software engineers and computer programmers engage with others to discuss programming concerns. You can post your question from there. This way, our engineers can provide you the best code to pass a bill number into the payload using PHP Software Development Kit.

 Here's how:

1. Go to this link: https://help.developer.intuit.com/s/.
2. Under the What do you need help with? section, choose QuickBooks Online. 
3. Click Ask a Question. 
4. Log into your existing Intuit Developer Account or create a new one. 
5. Enter your concern, then select Ask. 

Additionally, you can always visit our SDKs Guide to help you build apps and integrate them with QuickBooks Online Accounting API.

I'm just a post away if you have any other concerns or follow-up questions. Have a pleasant day ahead.
