Flow building restrictions

This page describes the rules you must follow when building TellUs flows to ensure they compile correctly and customers don’t run into issues at runtime.

Authentication sections​

When a section contains authentication node, that section must follow a strict layout rule to avoid issues with node processing.

Rule​

If a section includes any Authentication node (except Silent Authentication and Weak Authentication), that same section must not contain other visual nodes that require user input.

What is allowed in an Authentication section​

What is not allowed​

  • Any visual node that requires the user to provide input (for example: input text, input choice, policy choice, file upload etc.) together with an Authentication node in the same section.

Examples​

Invalid auth section

Error message​

If a section contains an Authentication node together with visual nodes that require user input, an error is raised when validating the flow.
