Overview

SRT API is intended to expose details related to a SRT code, its description, timesheet, model, product line, region etc. This enables the DMS providers to have information on the rates, work units at the time of creating a flat rate work order repair/quote. A DMS provider can query the SRT data on a real time basis by providing the Vehicle Identification Number (VIN) or the Model Number. The API provides information that are available in Smart basket application today for the given equipment or model after filtering information that might not be useful for the dealers. All the SRT and its relevant data are extracted from the Smart Basket system of CNHi. Please refer to diagram below for information on the data flow of this interface.

1 working unit = 6 minutes

Pre-requisites

• Dealer must use their Dealer Portal credentials to authorize API call.
• Each DMS provider will have a Subscription key assigned by CNHi team, please reach out to dlnadmssupport@cnh.com for assistance
• Each Subscription key is unique to DMS and the environment it belongs to.

Authentication

• DMS will pass Basic auth in HTTP header with username/password
• Each DMS provider will have a subscription_key assigned by CNHi team, please reach out to dlnadmssupport@cnh.com for assistance
• The UserID and Password will be set up in the Dealer Portal by the Dealer uniquely for DMS access to interfaces
• DEP API will require subscription_key in HTTP header to identify client

API Format

• REST

The DEP takes care of the format transformations (as needed) to process the request and provide a response to the DMS system. New development for this interface are always recommended to the build to REST API for greater simplicity.

Connection Details

For SRT there's 3 API types offered:

• Parts APIs
• VIN APIs
• VIN & Parts APIs

CNHi provides two environments for its APIs:

• Cert/UAT
• Production

The environments are identical, requiring only that you change out your connection string and authorization endpoint to connect to any of the environments.

VIN APIs

VIN APIs can be summarized in 4 parts: Group, Subgroup, Subsubgroup and Operation. Because of that, CNHi offers 4 APIs:

• Group API
• Subgroup API
• Sub Subgroup API
• Operation API
