I am trying to get Zoho and another software program to talk to each other.

I use 2 software programs:

1. Zoho (CRM)

2. SoftwareOne

I want to do the following:

1. Create a custom field in Zoho (Policy Number)

2. Enter policy number (POL1234) in SoftwareOne and Save

3. When data is saved in SoftwareOne, the details appear in my Zoho custom field (Policy Number: POL1234)

SoftwareOne uses REST API web services and I have been able to use a string to make the data appear in a browser, but there is nowhere in Zoho that I can find where I can put this string to gather the data.

I am not a developer and am not using Zoho creator.

What is the best way to do this?
