The purpose of the Business Messages Work Group is to provide technical support and guidance to other PIDX groups with regard to message construction, transmission protocol, and document security. This support includes maintenance of the PIDX XML schemas, implementation guides, and the Petroleum Industry Data Dictionary. We believe that adherence to business message and protocol standards promotes efficiency and enhances security in e-Business, and we seek to promote these standards globally.

The Work Group has developed business message standards for invoicing, purchasing, supplier price sheets, field tickets and many other aspects of the Quote to Cash cycle. We encourage involvement by buyers, suppliers, network providers and others to make sure all viewpoints are considered.

Our meetings are conducted in full compliance of all national, regional, and local laws, regulations, and ordinances including those of other relevant jurisdictions and subscribing to PIDX’s Antitrust Compliance Guide adhering to PIDX’s policy on Compliance with Antitrust Laws. General meetings are open to all interested parties, regardless of PIDX Membership Status. 

Current Projects

PIDX Web Services Usage Guideline - Since 2006, the adoption of web services interfaces for e-commerce and related transactions had grown considerably.

As PIDX attempts to increase its adoption beyond large North American companies, two limitations have become apparent.

Some national oil companies (NOCs) and large private companies outside of North America resist adopting any e-business standard that requires the use of the existing approved PIDX protocols. These companies have corporate mandates requiring the use of Web Services for integrations with trading partners.

At the other end of the scale, the expansion of shale exploration has produced a large number of small to medium enterprises (SMEs), both suppliers and operators, who do not have the capability to manage messaging servers. They may not even have static IP addresses or even persistent internet connections. For these SMEs, implementation of PIDX processes and documents is not possible using either RNIF 2.0 or AS2.

PIDX does not currently have any standard or business process guideline for implementing a Web Services integration that could overcome these two barriers.

*This version of the standard is rescinded. We are initiating a new project to focus on a more specific guideline for using XML messaging within Web Services and also including REST APIs with json. To join the project, please email
