Function Version
Function Versions are specific versions of JavaScript Node.js code that execute at a particular domain.
The steps to create Functions are as follows:
- Create a Function
- Create a Function Version (this resource) by making a POST request to
https://serverless-upload.twilio.com
You will need the Function Version SID that the create request returns to include this Function in a Build.
Function Version properties

|---|---|
sid
|
The unique string that we created to identify the Function Version resource. |
account_sid
|
The SID of the Account that created the Function Version resource. |
service_sid
|
The SID of the Service that the Function Version resource is associated with. |
function_sid

The SID of the Function resource that is the parent of the Function Version resource. |
path
|
The URL-friendly string by which the Function Version resource can be referenced. It can be a maximum of 255 characters. All paths begin with a forward slash ('/'). If a Function Version creation request is submitted with a path not containing a leading slash, the path will automatically be prepended with one. |

Create a Function Version resource
A Function Version resource is created by making a POST request to the following, dedicated URL:
https://serverless-upload.twilio.com/v1/Services/{ServiceSid}/Functions/{FunctionSid}/Versions
The following example creates a Function Version resource using the language of your choice (or curl) and an external file, firstfunc.js, which contains the function body.
Note that the Serverless upload endpoint is on a different subdomain from the rest of the Serverless API (serverless-upload.twilio.com instead of serverless.twilio.com), and is not supported by the Twilio Helper Libraries at this time.
The create action accepts these parameters:
| Parameter | Description |
Content |
The Function code to upload as a JavaScript file. |
FunctionSid |
The SID of the Function resource to upload this code to. |
Path |
The path to assign the Function. Must be URL Friendly, without fragments, and the characters ;,?:@+&$()' " are disallowed. |
ServiceSid |
The SID of the Function's Service. |
Visibility |
The visibility of the Function. Can be public, protected, or private. |
