Step Functions

Step functions are the operations a connector runs, one step at a time, to carry out an action or set up events. Each step takes parameters and returns output that later steps and the result of the action or event setup can use. See Expression Language for how to reference a step’s output.

Step shape

Steps take one of two shapes:

SimpleStep
ForeachStep

Runs one step function once.

Field	Description	Type	Required
`condition`	JEXL expression gating whether this step runs.	string	No
`description`	Explains what this step does.	string	Yes
`ignoreError`	Whether a failure in this step is ignored so execution continues.	boolean	No
`onConditionError`	How to behave when the condition expression errors: `false` (default) skips the step, `true` runs it anyway, and `break` halts the action. Allowed: `true`, `false`, `break`	enum	No
`stepFunction`	Step function executed by this step.	object	Yes
`stepId`	Identifier for this step, used to reference its output.	string	Yes

steps.stepFunction

Step function executed by this step.

Field	Description	Type	Required
`functionName`	Name of the step function to execute.	string	Yes
`parameters`	Arguments passed to the step function.	object	Yes
`version`	Version of the step function to use.	string	No

Runs one or more step functions once for each item in the array its iterator resolves to.

Field	Description	Type	Required
`condition`	JEXL expression gating whether this step runs.	string	No
`description`	Explains what this step does.	string	Yes
`ignoreError`	Whether a failure in this step is ignored so execution continues.	boolean	No
`iterator`	Expression that produces the array this step loops over. The step function(s) run once per item until the array is exhausted, halting early if an item fails and `ignoreError` is not set.	string	Yes
`onConditionError`	How to behave when the condition expression errors: `false` (default) skips the step, `true` runs it anyway, and `break` halts the action. Allowed: `true`, `false`, `break`	enum	No
`stepFunction`	Step function run for each iterated item. Provide this or `stepFunctions`, not both.	object	No
`stepFunctions`	Step functions run in sequence for each iterated item. Provide this or `stepFunction`, not both.	object[]	No
`stepId`	Identifier for this step, used to reference its output.	string	Yes

steps.stepFunction

Step function run for each iterated item. Provide this or stepFunctions, not both.

Field	Description	Type	Required
`functionName`	Name of the step function to execute.	string	Yes
`parameters`	Arguments passed to the step function.	object	Yes
`version`	Version of the step function to use.	string	No

steps.stepFunctions

Step functions run in sequence for each iterated item. Provide this or stepFunction, not both.

Field	Description	Type	Required
`functionName`	Name of the step function to execute.	string	Yes
`parameters`	Arguments passed to the step function.	object	Yes
`version`	Version of the step function to use.	string	No

Requests

Calls that send a request and return a response for later steps to use.

request

Sends an HTTP request to the provider’s API and returns the response.

paginated_request

Sends HTTP requests to a paginated endpoint until it has one page of results, then returns a cursor for the next page.

soap_request

Sends a SOAP request to the provider and returns the parsed response.

soap_paginated_request

Sends SOAP requests to a paginated endpoint until it has one page of results, then returns a cursor for the next page.

mcp_request

Calls a tool on the provider’s MCP server, or lists the tools it offers.

code_execution_lambda

Invokes an AWS Lambda function, returning its response when invoked synchronously.

call_action

Runs another action and returns its result.

Authentication

Prepare credentials that later requests use for authorization.

sign_jwt

Signs a JWT with a private key, for later requests to use as a credential.

Transform Data

Work on manipulating data already available in the action from the current context and previous steps.

map_fields

Maps fields from source data onto the shape the action returns.

typecast

Converts fields in source data to their declared types.

group_data

Combines the output of several earlier steps into one record or list.

static_values

Returns fixed values, or the result of an expression.

Files

Upload files to a provider or download them from one.

upload_file

Uploads a file to the provider as a multipart form.

upload_binary

Uploads raw binary content to the provider.

download_file

Downloads a file from the provider, as a buffer or a stream.

Events & Automation

Start work outside the action’s request and response flow.

emit_event

Emits an event with a type, date and payload.

browser_use

Runs a task in a browser session, starting at a given URL.
