The SAO Technology Division is the main point of contact for WOLFS and Payroll system interfaces (setup, testing, coordination and production) and our email is: SAOInterfaces@wyo.gov

Please refer to the SAO Processing Calendar for interface deadline exceptions. In order to process your interface for the current day’s WOLFS payment run, we need your interface file transferred to the SAO Relay Box no later than 5:00 pm.

NOTE:  Due to inconsistent results when the WOLFS cycle is processing, it is highly recommended that files not be uploaded or authorized from 5:00PM to 12:00AM.  It is also recommended that a file should be authorized in WOLFS or Payroll on the same day the file was uploaded.

The WOLFS and Payroll systems currently in use by SAO allow for the importing of certain types of transactions from Agency systems for the efficient exchange of data with the official State-wide financial and payroll systems. Implementing a new interface from an Agency system with the WOLFS or Payroll systems requires planning and extensive testing of the new interface before an interface can be approved for production use in WOLFS or Payroll. Whether an Agency needs a new interface or simply to update an existing interface, the requirements and testing process are basically the same, although new interfaces typically require many more test iterations before approval for production is granted. The SAO will not allow an interface to run in our production system which has not been fully tested, with issues vetted and resolved, and with approval from the SAO.

Payment requests (such as GAX and PRC transactions) and internal transfers (such as IET transactions) are most commonly interfaced to WOLFS from agency systems.

Employee work time and leave usage (TADJ transactions) can be interfaced to Payroll from an agency time keeping system. Only pre-approved agency time keeping systems can be interfaced. Please contact SAO prior to procuring a time keeping system for your agency to determine if interfacing the data will be an option for your agency.

If you are having trouble generating your file, we may be able to assist as you work to resolve your issue. Please contact the SAO Technical Division (SAOInterfaces@wyo.gov) and let us know you are having issues with your file to advise us of your situation. Please provide your contact information. If you have an ETA for when we can expect your interface file, please include the details. We will check our processing and let you know what options are available (ex: if we can give you more time for this current run). 

If you are having trouble transmitting your interface file, please contact the SAO Technical Division (SAOInterfaces@wyo.gov) right away. We will work with you to determine an alternative method for the current interface file transmittal.

All interfaces are required to use XML file format based on our specifications for tags, content, etc. as determined by the current system options and configuration.

The SAO will provide the Agency the appropriate file formats for the interface transaction which includes the detail fields required, format/layout and examples to the Agency based on the initial meetings. Note that each file must contain transactions of one type – and cannot be a mix of transaction types.

At the point the Agency is working on the design of a new system or a revision to an existing system for an interface with the SAO WOLFS or Payroll systems, they should meet with the SAO to coordinate the interface process and to learn the current requirements, options and limitations. When meeting with SAO, the Agency would include their fiscal (functional, WOLFS or Payroll users) representative(s), their system (technical, project manager) representative(s) and their program specific and/or fiscal management representative(s). When meeting with the Agency, the SAO would typically include the fiscal (functional support for the WOLFS or Payroll system from the SAO Fiscal Managment Division) manager and team representative(s), the systems (SAO Technical Group) manager and team representative(s) and a the SAO Quality Assurance division who will audit the agency system prior to the interface being approved for production use.

New interfaces require an Agency (or an Agency’s vendor) to develop processes, programs and/or procedures, as is appropriate and necessary to submit interface documents to be loaded and processed in WOLFS or Payroll. The required elements for interfacing with WOLFS range from setting up the fiscal data as used in the WOLFS system (ensuring proper setup of budgets, charts of accounts – COA, etc.), the technical components (generation and delivery of the electronic interface file, access to the results of a WOLFS run, etc.), and the control/approval environment (verification of interface data, delivery of the certification report to the SAO, etc.).

An agency must complete the Agency Interface Request Form and this form must be approved by the Wyoming State Auditor’s Office prior to beginning work on an interface.  An agency should allow up to 30 days for the form to be reviewed and approved before interface work can begin.

Once the “Agency Interface Request Form” is approved, the Agency and SAO will meet to discuss a new interface, the SAO will assign an interface number, if this is a new interface. Transferring of data with the SAO systems is done using secure FTP and requires the Agency to provide static IP addresses (IPs) which will be used in the transfer of the data. SAO will allow up to 3 IPs per interface to allow for multiple Agency users (such as test, user acceptance, production). Once the Agency provides the IPs, the SAO will setup the secure FTP location for the Agency to use when transferring files with the SAO systems. The procedures to set up these secure FTP locations can take several weeks to complete and is based on the SAO hosting vendor requirements. The secure FTP location is also referred to as the SAO Relay Box.

Initial testing may be as simple as validating the file is in the correct format (either visually inspected or compared to an existing XML file using file comparison tools or SAO verifying the transaction count and total amounts). If the file format is correct, test files may be test loaded to check the correctness of the data with a partial WOLFS test run as a rapid verification. While a majority of interfaces can be developed and tested quickly, an agency should allow up to thirty (30) days for interface development work to be completed before testing occurs.

Once the Agency is ready to test their interface file, the Agency will transfer the test files to the SAO Relay Box and notify the SAO Technology Group they are ready for a review of the interface file (such as to test the format of the file) and/or they are ready for a test of their interface. All notifications should be done via email to saointerfaces@wyo.gov. Please include at least the interface number and the word “Test” in the subject of all emails (e.g. “Test IXX interface”). The Agency should provide a certification request with each interface test. This will allow for the certification request to be vetted and approved during the multiple testing iterations as well. For interface tests, the certification request can be provided electronically on the SAO Relay Box.

The SAO will attempt to complete each test within 3 business days (may vary depending on time on other priorities, schedule, etc.). If for some reason the SAO is unable to complete testing in 3 business days, the Agency contact that requested the testing will be notified. The detail results from the test will be provided back to the Agency via email. Note that some rejects may occur due to out of date data in the system test regions (e.g missing vendor customer codes, budgets, etc.). The SAO attempts to update the data in the system test environments from the production environment monthly. However, the data points could cause issues with the test results and may not include all of the changes made in the previous or current months.

An agency must complete the Agency Interface Request Form and this form must be approved by the Wyoming State Auditor’s Office prior to beginning work to change or replace an interface.  An agency should allow up to 30 days for the form to be reviewed and approved before work can begin.

Once the “Agency Interface Request Form” is approved, the Agency and SAO will meet to discuss system changes or interface replacement.  When an Agency makes any changes to their interface process, the SAO recommends testing the interface with the SAO systems. This is necessary to minimize potential risk of rejecting a high number of payment documents or being unable to process a complete interface in production.

To request a test for updates to an existing interface, the Agency will transfer the test files to the SAO Relay Box. The name of the test file should not be the same as the production file name (to minimize the risk of the incorrect file being used for this interface). Once the Agency has transferred the file to the SAO Relay Box, the Agency should notify the SAO Technical Group they are ready for a test of the interface. All notifications should be done via email to saointerfaces@wyo.gov. Please include at least the interface number and Ready to test in the subject of all emails (e.g. I## GAX Ready to test). The email should contain the name of the interface file transferred to the SAO Relay Box for testing. The Agency should provide a certification request with each interface test. This will allow for the certification request to be vetted and approved during the multiple testing iterations as well. When an interface is being tested and the agency provides a certification email, please make sure it is clearly marked test. While most changes to an existing interface can be made fairly quickly, an agency should allow up to thirty (30) days for interface changes to be completed before testing occurs. 

The SAO will attempt to complete each test within 3 business days (may vary depending on time on other priorities, schedule, etc.). If for some reason the SAO is unable to complete testing in 3 business days, the Agency contact that requested the testing will be notified. The detail results from the test will be provided back to the Agency via email. Note that some rejects may occur due to out of date data in the system test regions (e.g missing vendor customer codes, budgets, etc.). The SAO attempts to update the data in the system test environments from the production environment monthly. However, the data points could cause issues with the test results and may not include all of the changes made in the previous or current months.

Please contact the SAO Technical Division (SAOInterfaces@wyo.gov) and request the addition or deletion of the IP addresses for the particular computer/server which needs access to the SAO Relay Box to be added or removed from within the State of Wyoming network. Any access outside the state’s network, will need to request access to the State of Wyoming Relay-box (MoveIT Server) through ETS)
