Add a webhook step to an existing workflow template. This endpoint allows you to configure individual steps within a workflow, including execution order, conditions, retry logic, and template variables.

Request body

Field	Type	Required	Description

`path`	string	Yes	URL path for the webhook (supports template variables)
`domain_uuid`	string	Yes	UUID of the domain associated with this webhook step
`human_approval_required`	boolean	Yes	Whether this step requires human approval before execution
`step_identifier`	string	Yes	Unique identifier (slug) for this step
`on_success_next_step_identifier`	string	Yes	Step identifier to execute next on success
`on_fail_next_step_identifier`	string	Yes	Step identifier to execute next on failure
`delay_to_next_step`	integer	Yes	Delay in seconds before executing the next step
`execution_condition`	object	No	Condition that must be met for this step to execute
`execution_condition.operator`	string	No	Comparison operator: `"eq"`, `"ne"`, `"lt"`, `"gt"`, `"lte"`, `"gte"`, `"in"`, `"contains"`
`execution_condition.field`	string	No	Field path to evaluate
`execution_condition.value`	string	No	Value to compare against
`retry_delay`	integer	Yes	Delay in seconds between retry attempts (default: 10)
`retry_backoff_mode`	string	Yes	Retry backoff strategy: `"linear"` (default) or `"exponential"`
`max_retries`	integer	Yes	Maximum number of retry attempts (default: 5)
`request_timeout_in_milliseconds`	integer	Yes	Request timeout in milliseconds (default: 5000)
`request_body_json`	object	Yes	Request body as JSON object (supports template variables)
`headers_json`	object	Yes	HTTP headers as JSON object (supports template variables)
`query_params_json`	object	Yes	Query parameters as JSON object (supports template variables)

Execution Order (Index)

The index field defines the priority and execution order for FIFO (First-In-First-Out) workflows:

Lower index = Higher priority: Steps with lower index values execute first
Index 0: First step to execute
Sequential execution: In FIFO mode, steps execute in order based on their index
Concurrent mode: Index may still be used for reference, but steps execute in parallel

Execution Conditions

The execution_condition field allows you to control when a step executes based on field values:

Supported Operators

Operator	Description	Example
`eq`	Equal to	`amount eq 100`
`ne`	Not equal to	`status ne "cancelled"`
`lt`	Less than	`quantity lt 10`
`gt`	Greater than	`price gt 1000`
`lte`	Less than or equal to	`age lte 18`
`gte`	Greater than or equal to	`score gte 80`
`in`	Value in array	`status in ["active", "pending"]`
`contains`	String contains substring	`email contains "@example.com"`

Example Execution Condition

{
  "execution_condition": {
    "operator": "gt",
    "field": "amount",
    "value": "1000"
  }
}

This condition ensures the step only executes if amount > 1000.

Template Variables

Workflow steps support dynamic variable substitution in request_body_json, headers_json, query_params_json, and path:

System Secret Variables

Access secrets from the System Secret Vault:

{{ #key }}

Example:

{
  "headers_json": {
    "Authorization": "Bearer {{ #api_key }}"
  }
}

Step Response Variables

Access data from previous workflow steps (FIFO mode only):

{{ step.response.variable }}

Example:

{
  "request_body_json": {
    "payment_id": "{{ step.response.payment_id }}",
    "status": "{{ step.response.status }}"
  }
}

Initial Variables

Access variables from initial workflow input (FIFO mode only):

{{ initial.variable }}

Example:

{
  "request_body_json": {
    "user_id": "{{ initial.user_id }}",
    "order_total": "{{ initial.total }}"
  }
}

Note: In concurrent mode, only system secret variables ({{ #key }}) are available. Step response and initial variables are not supported in concurrent execution.

Step Flow Control

Success and Failure Paths

on_success_next_step_identifier: Defines which step to execute next when this step succeeds
on_fail_next_step_identifier: Defines which step to execute next when this step fails
delay_to_next_step: Adds a delay (in seconds) before executing the next step

Human Approval

When human_approval_required is true:

The workflow pauses at this step
A human must approve or deny the step before execution continues
This provides manual intervention capabilities for critical operations

Example response

{
  "success": true,
  "details": "Workflow webhook added successfully"
}

Response fields

Field	Type	Description
`success`	boolean	Indicates if the request was successful
`details`	string	Success message
