Overview

Chewatch WebService API provides an easy and robust way of getting data from Chemwatch based on parameters selected in a request. It exposes a simple to use REST interface that can be implemented in any programming language capable of working with Web. It also exposes more sophisticated native .NET SOAP interface with WSDL (preferred method for .NET programming).

All operations start with creating a "session". The session is persistent and exists until connection is terminated or times out. The session has a unique identifier, a security token that should be provided to the server on every call following authentication.

Chemwatch WebService API has all the required functions to do the following operations:

• Search Chemicals by Name, Synonym, CAS or internal ID (Chemwatch Number: CW No)
• Retrieve (M)SDS data-points on a selected chemical (Between 30 and 500 (M)SDS end-points available, depending on the type of record)
• Retrieve Regulatory data-points on a selected chemical (up to 6,000 end-points available, depending on the chemical)
• Retrieve documents in PDF format (one of many selected types of documents including SDS, Label(s), MINI-Reports, etc.).

Chemwatch API is the most efficient method of integrating extensive chemical data and documents into ERP systems, laboratory systems, websites, online stores, and custom software platforms with minimal effort.

Note: For SOAP and WSDL please check further.

Requests

The Chemwatch Web API is based on REST principles: data resources are accessed via standard HTTP requests to an API endpoint.

All requests to the API require authentication. Authentication request, if completed successfully, provide a session cookie that should be attached to all subsequent requests (for more information see below).

Responses

All data is received as XML or JSON object.

Response HTTP Status Codes

Error Details

Unsuccessful responses return information about the error as an XML (or JSON) object containing the following information:

This Method is recommended where:

• Large Collection of data points are required per request
• Consistent collection of DP is required on an ongoing basis (e.g. GHS Label Data Method will return 15 end points required to populate a "label")
