I’m working with two separate workflows and need to figure out how to send data from one to the other. My setup involves a first workflow that generates a numeric value through a Python script. This value needs to be passed to a second workflow that I trigger from the first one.
The second workflow (named “Student Record Manager”) contains a variable called ‘Record ID’ that should receive the number generated by the Python script in the first workflow. I can successfully call the second workflow from the first one, but I’m struggling to understand how to actually pass the generated value and update the variable in the target workflow.
Is there a standard way to handle variable passing between workflows? What’s the proper method to ensure the data flows correctly from the source workflow to the destination workflow’s variables?
The challenge you’re facing typically arises from the way variables are passed between workflows. To resolve this, make sure to define ‘Record ID’ as an input parameter in the Student Record Manager workflow. This allows you to directly connect the output of your Python script to the input of the second workflow. When you initiate the second workflow, just ensure that the invocation includes the ‘Record ID’ parameter. This situation is often encountered by users, particularly during the triggering phase. It would be helpful to refer to your workflow engine’s documentation for specific guidance on parameter setup.
I’ve hit this same issue with workflow orchestration. The thing most people miss is proper data serialization - your Python script output has to be in a format the next workflow can actually read. Most workflow engines make you explicitly map the output variable from workflow #1 to the input parameter of workflow #2 during invocation. Check if your platform supports passing variables through environment variables or shared data stores instead. When I debug this, I always verify the variable names match exactly between the first workflow’s output declaration and the second workflow’s input parameter definition. Also double-check that the data types are compatible.
