Secure

Streamscript runs exclusively on Salesforce - no data passes through any other server.

 

Bring CSV, XML, JSON capabilities (webhooks and more) directly into flow using Streamscript, and benefit from flow security settings, flow versioning and flow tests.

 


 

Get started

You can replicate this in your own org:

  1. Install the Streams package in Sandbox or Production (direct URL)
  2. Go to Setup > Flows > New Autolaunched Flow
  3. Add an action element, type: Streamscript
  4. Copy and paste the above exchange rate example into your step
  5. Save the flow, then click debug.

That's it! You just integrated live exchange rates into your flow.

Q & A

 

Q: Where is the package?
Here is the install URL: /packaging/installPackage.apexp?p0=04tGA000005VVeA

Q: What is inside the package?
The package contains: 1 custom object, 5 apex classes, and 1 LWC for the script editor.

Q: I'm not a coder, can I use Streamscript?
Yes. If you've used formulas, it will feel familiar. Try our AI Prompts tutorial video and generate your first script automatically instead of starting from scratch.

Q: Is the package security reviewed?
Yes. Latest details here. Streams is published on the AppExchange with Aloha status from Salesforce. At install you can click 'View Components' to verify it contains no integrations.

Q: Is this related to OmniScript, Mule DataWeave scripts, or AMPscript?
No. Those are external hosted environments. Streamscript only runs in native Salesforce flows.

Q: Is this free? What do you gain in return?
Yes. In return we hope you'll consider us for your next project.

Q: Can I offer script capabilities in my company's package?
Yes. Contact us and we will assist.

 


 

Q: How do I get syntax highlighting and autocompletions?
We use this optional Chrome Extension or Firefox Add-on in our videos.
Follow the extension install steps. Our playground also provides highlighting.

Q: Does it support bulkification?
Yes. Best practice for record-triggered flows is to use the Bulk directive. In bulk mode, Streamscript will run once instead of many times. Inputs or merge fields will contain lists instead of a single value. Outputs or return values will expect lists instead of a single value.

Q: How do I make an API call from a Record-Triggered Flow?
Salesforce supports HTTP from record triggers, but the script must be asynchronous. Move the callout logic from "Run Immediately" to the "Run Asynchronously" path. This will resolve errors such as "You have uncommitted work pending. Please commit or rollback before calling out". Use the Bulk directive to transmit up to 200 records in each request.

Q: How do I set response headers on my inbound webhook?
Use the variable $Webhook.responseHeaders to set response headers. Without overwriting the map, add values like this: $Webhook.responseHeaders.Content-Type = 'text/xml'

Q: How can I send auth headers in my HTTP callout?
Set up a Named Credential then use as follows: Http-Post 'callout:My_Cred/path/to/api'
Avoid handling session ids, usernames, passwords or authentication tokens within your logic.

Q: Why is %7B%21%24 appearing in my named credential or external credential?
You URL encoded the {!$Credential.Password} or used toUrl on it. Take care to separate the credential from other params, then append it to the request body to preserve it unencoded.

Q: How to convert a UNIX epoch timestamp (in seconds) into a datetime?
Add the timestamp to 1970-01-01 like this: $dt = Datetime 1970 1 1 0 0 $timestamp -gmt
Or like this, for timestamps in milliseconds: $dt = Datetime 1970 1 1 0 0 0 $millis -gmt

Q: Can I access all of the fields on my records?
Streamscript supports all fields on all objects, including standard, custom, managed, platform events, and custom metadata, wherever the running user has CRUD and FLS permissions.

Q: How do I send URL encoded form data in an HTTP post?
Prepare a map of parameters, then use toUrl which converts it to text in key=val format:

# Post form data
$url = 'httpbin.org/post'
$body = {id: '123', type: 'order'}.toUrl()
$headers = {Content-Type: 'application/x-www-form-urlencoded'}
return Http-Post $url $headers $bodyTry

Q: How can my Webhook receive URL encoded form data posted to it?
Read map values off $Webhook.requestParams (the $Webhook.request body will be blank)

# Webhook
return New-Case {
    Subject = $Webhook.requestParams.issueId,
    Description = $Webhook.requestParams.issueSummary
}Try

Q: How do I get nested or parent record attributes in a Record Triggered Flow?
Use a query, or create formulas so that the related fields are availed on the record:

# Streamscript to get parent record attributes
$Contact = Query-Record 'SELECT Account.Owner.Name FROM Contact LIMIT 1'
return $Contact.Account.Owner.NameTry

Q: How do I access the results of script in subsequent steps?
One-line scripts automatically return the result of the expression. Streamscript will set the output variable (num, bool, text, list, record, records) according to the result data type.
Multi-line scripts use the return keyword. For example: return $num or return $list
When returning SObjects, the variable name must be the type, eg: return $Invoice__c
Note flow API names are case sensitive: $name__c $Name__c $Name__C are different.
