You are encouraged to review the information and materials provided by the IPAWS Developers section of the FEMA IPAWS website.

In order to access the IPAWS OPEN test environment, a Memorandum of Agreement must be executed with FEMA. Please see the instructions provided on the FEMA IPAWS website. Once fully executed by both parties FEMA will send you:

  • Copy of the fully executed MOA
  • IPAWS-OPEN v3.01 Web-Service Interface Design Guidance
  • Digital Certificate
  • Accessible Web Service End Point

After reviewing the documentation, you will be asked to identify the specific functions of IPAWS you wish to use, for inclusion in the IPAWS-OPEN-maintained test results database. As you test, you will work with the IPAWS test coordinator to ensure that successful results are reported and problems are resolved as needed.

You are invited to participate in monthly Webinars designed to assist developers with IPAWS-OPEN implementation. Please see the FEMA IPAWS Working Group Schedule page for further information.
