Explain the implementation of ServiceNow Third party integration Bi-directional?

[JPGServiceNow]

My company's customer uses ServiceNow. We provide service through our helpdesk.
I have to integrate my customer's ServiceNow into our helpdesk.
My company can't afford the ServiceNow TPP program to create a ServiceNow App.
Can I create an integration in my PDI and install it to test in their DEV/TEST (like AddtoUpdateSet from "Share")?
Which scope is best while creating this integration, Global or Scope?

Thanks in Advance.

You can test application ideas but the PDI is not intended for business or production use https://developer.servicenow.com/dev.do#!/guides/utah/developer-program/pdi-guide/personal-developer...

You need information regarding your customer's instance to determine the best integration method. Your customer should have a developer or architect that leads on this.

Hello

It is always essential to understand business requirement/use case before any development to begin with.

here is a scenario:

1. your company’s customer uses ServiceNow and want to integrate with web help desk that you use in your company to support the same customer.

2. To establish bi-directional sync between these two systems, it is evident that exchange of data will happen.

3. This data transaction can be large or medium or small (you know it better).

4. Based upon the above, among multiple ways of integration, one can be chosen; let’s say the common one i.e outbound rest message in ServiceNow (if and only web help desk supports REST or have json payload).

5. If your company’s customer has ServiceNow, they will have developer too which can configure outbound rest message and can develop mechanism like flow, BR, UI action etc. to make GET/PUT/POST requests to web help desk.

6.If their devs are not available or don’t have bandwidth where you want to support then it is definitely commendable of you however this need some ServiceNow development skills to achieve and definitely the platform to try and test which is where customer’s non-prod instance is the best to work.

7.  You can learn integration between two PDIs (create from your two personal e-mail).

8. Use one of the PDI to create KB article with all the steps and share with your customer (if allowed).

Maybe later, your customer’s dev/admin can collaborate with you to achieve the same.

Hope that helps!
