HTTP Request Step

The HTTP Request step lets you connect your CloudTalk call flows with external systems and APIs. In this guide, you’ll learn how to configure and use the HTTP Request step to send requests, handle responses, and integrate external data directly into your call flows.

User level: Admin

Using an HTTP Request Step

The HTTP Request step lets you extend your call flows beyond CloudTalk by connecting to external systems and APIs. It enables data exchange, automation, and real-time decision-making during a call. Whether you’re enriching call data, updating external records, or personalizing customer experiences, the HTTP Request step gives you the flexibility to build smarter, more connected workflows.

Add an HTTP Request to Your Call Flow

From the Dashboard, click Numbers.
In the My numbers tab, find the number you want to configure.
Click + Configure (or the flow name, if one exists) in the Call Flow column.
On the canvas, click the + button where you want the step.
In the step library, under Automation, select HTTP Request.

Configuring HTTP Requests

6. Click the HTTP Request step on the canvas to open its config panel. The following elements are available:

Endpoint

The endpoint defines the URL to be called. Communication requires HTTPS.

Method

The HTTP Request Method, or the type of action the endpoint receiver is being asked to perform. Available options: GET, POST, PUT, PATCH, DELETE.

Request Headers (optional)

Request headers provide meta-information about the request, such as the format of the request body or authorization credentials. Click Add new to define additional headers. The type of headers depends on the external API you’re connecting to.

Request Body

The request body is the payload sent with the request. Click Add new to define key-value pairs as data attributes. You can also click Add contact custom field to insert contact data directly. The request body is sent in JSON format (for example: {"key1":"value1", "key2":"value2"}). Apart from constant values, you can use the following dynamic variables: Call Attributes:

Variable	Description
`#{{call.external_number}}`	Caller’s number in E.164 format (e.g., +10005555555)
`#{{call.waiting_time}}`	Time in seconds between call start and agent pickup
`#{{call.uuid}}`	Unique call identifier
`#{{call.agent_id}}`	Agent ID (only on an answered branch, otherwise returns null)
`#{{call.agent_email}}`	Agent email (only on an answered branch, otherwise returns null)

Contact Attributes:

Variable	Description
`#{{contact.name}}`	Contact name
`#{{contact.id}}`	Contact ID
`#{{contact.title}}`	Contact title
`#{{contact.company}}`	Contact company
`#{{contact.industry}}`	Contact industry
`#{{contact.address}}`	Contact address
`#{{contact.city}}`	Contact city
`#{{contact.zip}}`	Contact ZIP code
`#{{contact.state}}`	Contact state
`#{{contact.type}}`	Returns “contact” or “lead”
`#{{contact.tags}}`	Returns array of assigned tags (e.g., `["Vip", "CampaignA"]`)
`#{{contact.custom_fields["field_name"]}}`	Value of a custom field (e.g., `#{{contact.custom_fields["MRR"]}}`)
`#{{contact.emails}}`	Returns array of contact emails
`#{{contact.emails[0]}}`	Returns the first email from the array

Collect Input:

Variable	Description
`#{{input[step_id].value}}`	Value entered by the caller during a Collect Input step. Replace step_id with the Step ID of the Collect Input step (e.g., `#{{input[389008].value}}`).

Tip: Save your flow before referencing a Step ID. Before saving, steps have temporary negative IDs that may not work correctly. After saving, the Step ID becomes a permanent positive number.

Note: Collect Input can return empty if the caller didn’t enter a value. During initial creation, you can use the temporary ID; it will be replaced after the flow is saved.

Nesting Options

If an external endpoint requires nested objects, use dot notation in the Key field: key.subkey. For example:

customer.firstname = John
customer.lastname = Doe

Results in: { "customer": { "firstname": "John", "lastname": "Doe" }}

Parse Response

The Parse response checkbox defines how CloudTalk handles data received from the external system.

When disabled The call flow continues immediately after sending the request, without waiting for a response. Useful for fire-and-forget requests where the response data is not needed.

When enabled The call flow waits for the HTTP response before proceeding. The returned data is then available for use in subsequent steps.

Retain Data After Call

Check Retain data after call to keep the HTTP response data available after the call ends. This is useful if you need the data for post-call processing or reporting.

Using the Response in Later Steps

When Parse response is enabled, the response body can be used in a Condition Splitter to route calls based on the returned data. In the Condition Splitter config: 1. Select HTTP Response from the Property dropdown. It will show the endpoint URL of the HTTP Request step (e.g., “HTTP Response - https://api.example.com/customer”) so you know which request it references. 2. Enter the JSON path to the response property using dot notation. Example: If the response looks like:

{
  "status": "success",
  "error": {
    "code": 200,
    "message": "OK"
  }
}

To reference the top-level property status, use: status
To reference the nested property error code, use: error.code
For indexed (list or array) properties, use dot notation with the index number: status.0 for the first item, status.1 for the second, and so on.

3. Define the desired condition (Operand and Value) based on what you need to match.

With this setup, every time a call reaches the HTTP Request step, it sends a request to the external system. The response data then determines the call’s next routing path, allowing each call to be handled dynamically using the most up-to-date information.
