What API should I use to build an in-house integration for Magento & Suite CRM?

Hi guys,

We are selling furniture and plan to move from Salesforce into Suite CRM to manage & follow-up with my customers. We previously used this magento salesforce integration but now we wanna build an in-house integration for Magento & Suite CRM. Some fields we plan to build for matching between 2 systems:

  • Email
  • Purchase date
  • Shipping address
    And about 5 more fields we are considering. Can you tell me what API should I use for this integration? Also, how much time do you think it will take to build it?
  • 1 month
  • 3 months
  • More than 3 months

You would probably want to use the REST API for that.
