Solving the Missing Element Error in SOAP API Requests with Python's Zeep

When working with SOAP APIs, many developers encounter various errors that can sometimes be puzzling. One such issue arises while using the Zeep library in Python to interact with Workday’s SOAP API. Developers often receive error messages suggesting that a crucial element is missing from their request, even when they believe everything is included. Here, we will address a common issue related to the Missing element error and guide you through the solution step-by-step.

The Problem: What Does the Missing Element Error Mean?

In a scenario where you are trying to edit someone's Workday username, you may structure your request dictionary as shown below:

Despite having all elements in your request dictionary, you might see an error like:
zeep.exceptions.ValidationError: Missing element Workday_Account_for_Worker_Data (Workday_Account_for_Worker_Update.Workday_Account_for_Worker_Data).

This indicates that the API is unable to recognize the Workday_Account_for_Worker_Data, which could be due to how you're calling the API function.

Understanding the Cause of the Error

The root of this problem lies in the method signature for the Update_Workday_Account function. In order for the SOAP API to successfully process your request, it expects parameters in a specific format. This often includes multiple nested structures, and missing or incorrectly arranged parameters can result in validation errors.

To see the required structure, you can generate the API's WSDL file output using the following command:

Examining the output.txt will reveal the correct signature for the Update_Workday_Account function, which includes the following parameters:

From this, we learn that the parameters should be passed individually rather than as a single dictionary.

The Solution: Correctly Structuring the API Call

You need to reformat your code to pass each parameter separately. Here's how you can do this correctly:

Key Changes Made:

Individual Parameters: Each parameter (worker_reference, Non_Worker_Reference, workday_account_for_worker_data) is now sent separately.

Nil for Non-Worker Reference: Pass None if you do not have a Non-Worker Reference to include.

Conclusion

This adjustment should help you avoid the Missing element error and make your SOAP API requests function as intended. Always ensure that you are referencing the correct method signature from the WSDL file and passing the parameters in the expected format.

When working with APIs, it’s critical to adapt your code according to the specifications provided by the API documentation. If you continue to experience issues, consult the API documentation or community forums for further guidance. Happy coding!
