Make HTTP Request
Description:
Make HTTP Request allows you to interact with applications and code that live outside Studio. Use this widget to interact with parts of your business logic not defined in flows or as Functions.
Note: Returning custom TwiML from a Make HTTP Request widget isn't supported. Use the Run Function widget instead, and follow our guide for returning custom TwiML from Twilio Functions.
Required Configuration:
The required fields for this Widget are Request Method and Request URL. The Request Method can be selected from a dropdown, and the URL is able to be set as Automatic.
|
Name |
Description |
|
Request Method |
The desired HTTP method of your request (GET or POST) |
|
Request URL |
The URL you would like to make a request to. Tip: For secure URLs, add your Basic Authentication credentials. Example: |
| Content Type | Content type of the request body, either application/x-www-form-urlencoded or application/json. |
Optional Configuration:
You may optionally decide to declare a request body and HTTP parameters for this Widget.
|
Name |
Description |
|
Request Body |
Text to include as the body of your request. |
|
HTTP Parameters |
Key-value pairs of parameters to pass along with the request. String literals and variables are supported. |
Transitions:
This Widget has two events that trigger transitions.
|
Name |
Description |
|
Success |
A successful return (HTTP 20X) |
|
Fail |
The URL does not successfully return (or has an error) |
Response:
The HTTP response from the URL must return a 2xx status code within 10 seconds, and the response body must not exceed 64kB.
| Response | Recommendation | Notes |
| Status Code | 200 or 204 | 3xx redirection is supported. 4xx or 5xx status code will transition to "failed" in the widget. |
| Content Type | application/json | Content-Type header is not required if Status Code is 204 No Content. Other content types are supported, such as plain text or XML. But only application/json objects (e.g. {"foo":"bar"}) will be automatically parsed into Studio variables. |
| Body | valid JSON | Body content must match the Content-Type header. |
| Response Time | 10 seconds or less | Studio will timeout the request at 10 seconds and transition to "failed" in the widget. |
| Response Size | Maximum 64kb | Studio can only process responses up to 64kB. |
Variables:
Json: If your request returns an object in valid JSON, you will be able to access it via widgets.MY_WIDGET_NAME.parsed. Note that, although an array is valid JSON, if your request returns an array of objects, it will not be parsed.
For example, if you return {"message": "Hi", "person": {"name": "Bob", "age": 40}}, you can reference that in subsequent widgets as:
widgets.MY_WIDGET_NAME.parsed.message
widgets.MY_WIDGET_NAME.parsed.person.name
widgets.MY_WIDGET_NAME.parsed.person.age
For all return types, you will have the following variables:
widgets.MY_WIDGET_NAME.body
widgets.MY_WIDGET_NAME.status_code
widgets.MY_WIDGET_NAME.content_type
