How do i get data from other software system in to a field in a QB app using API call ? or any other way

Hello Raj, 

There are many QB sync options for connected tables, and there are a few api out there for editing records. 

I suggest starting with the Edit Record api or Import from csv api.

let me know if this helps.

You can also use a server side programming language, there are wrappers for a few languages like PHP, Java and Ruby.

The best program I have found for all integrations with Quickbase if you are willing to pay for a middleman, is Zapier. Quickbase is fully integrated already with Zapier so when you link your Quickbase domain and table you are wanting to mess with, it will have every single field you want. 

If you chose to go this option feel free to post here or reach out to me for further help and I can show you how easy every single API integration is with Zapier.

(no I do not work for Zapier)



EDIT: I just re-read your question, if you are wanting a 3rd party software to just POST to your CRM without you sending a response back it is very easy. Post back if this is what you want to do and I will give you instructions.
