Inject Variables node

The Inject Variables node resolves nested variable interpolation when a variable contains another variable inside its value. It performs a recursive replacement of placeholders defined with {{ }}.

This node is available in: Authentication, Admin, Self Service, API, Consent, Library, Custom, User Defined

Node configurations

• Inject depth: Defines how many recursive resolution steps are performed. Each step performs one level of variable injection.

  • depth = 1 — single interpolation pass

  • depth = 2 — nested variables pass (recommended for double interpolation cases)

  • Input: The {{nested Variable}} to be injected. For example: {{response.data.{{variable.value}}}}

• Save in the flow store: Save the result into a variable for reuse by other nodes. See Save in the flow store for details.

Default output node

• Success
• Invalid Depth
• Failure
