Start Node
The Start node is configured to trigger a flow using a channel, integration, webhook, or a custom event. This node allows you to configure the flow trigger in the context of the standard flow configuration. Further, the data from the trigger is available as node-level variables for use in the other flow nodes.
Start Node
While creating a new flow, you are prompted to configure the start node. You can choose either to configure or skip to do it later. Select a trigger and configure the details. Click the close icon at the upper right corner of the page to skip the trigger configuration.

Triggering a Flow on various Channel Events
| Channel | Possible Events |
|---|---|
| SMS | Mobile Originated - MO (Allows you to trigger the flow on an incoming SMS message) On Link Click Refer 'Conditional Trigger in SMS' section if you want to use the 'Trigger only when there are no live sessions option'. |
| Voice | Inbound Call Missed Call Note: Webex Connect offers the ability to trigger the same flow for incoming calls received on more than one phone number by using a routing number option. The mapping of the routing number with the set of phone numbers for dialing is to be configured by the Ops team. Reach out to Ops team if you want to use this feature._ Currently, the routing number feature is supported in the USA and Canada only. |

Trigger Conditions in Start Node
The platform allows selective triggering of the flow only when the conditions set on the trigger event are fully met. The list of variables on which a condition can be set is dependent on the trigger event. For example, conditions can be set on the inbound message or the sender number for an MMS trigger with an inbound message.
Different conditions on variables can be set using the AND/OR operators. When AND is part of the condition, that part of the condition must be true to qualify the condition. When OR is used, the statement is executed if any one of the conditions qualifies.
Inbound SMS with a condition on the text message set as trigger to invoke the flow
One of the several conditional operators that can be used to set conditions are listed below:
- Equals
- Not equals
- In
- Not in
- Contains
- Greater than
- Less than
- Greater than equal to
- Less than equal to
- Equals ignore-case
- Between
- Starts with
- Ends with.
Configure a Custom Event in Start Node
To configure a custom event:
- Create a flow.
- Select Custom Event as the trigger. Or, you can also double-click the Start node and select the trigger as Custom Event.
- Select an existing event or Create a new event based on your requirement. Enter a suitable name and configure the required variables. Provide a suitable name for the new event.
While configuring custom events within the Start Node:
- A pre-selected read-only checkbox is visible on the screen to highlight that it is mandatory to pass service authentication credentials when using Custom Event v1
Custom Event Configuration
- The sample payload is dynamically generated for API request body based on the configured parameters. The event id i.e.,
evtidfor the configured custom event is generated once you save the configuration.
Dynamically Generated Sample Payload
You can start using the custom events in the flows. When you use the custom event node in a flow, the event URL is auto-populated and authentication is mandated.
Conditional Trigger in SMS
Webex Connect allows you to conditionally trigger a flow on receiving an incoming SMS message only if the configured conditions are met. Here's how you can use this feature:
- Double-click the Start node and select 'SMS - Mobile Originated - MO' as the flow trigger.
- Provide the required details like SMS event, Incoming Number, and Keyword.
Conditional Trigger
When the Trigger only when there are no live sessions checkbox is enabled, the flow will be triggered only if no Receive node is waiting with a matching keyword and incoming number.
For example, let us suppose there are two flows Flow 1 and Flow 2:
Flow 1: The Start node in Flow 1 is selected as SMS and the keyword configured in the Start node is 'Help'. The next node is the Receive node with a (anything) keyword.
Flow 2: The Start node is Flow 2 is selected as SMS and the keyword configured in the Start node is (anything).
- If Flow 1 and Flow 2 are in the same service -
When there is an incoming message with the Help, Flow 1 is triggered. With the Help keyword, only the matching flow gets triggered (i.e., Flow 1). We have a Receive node in Flow 1, Flow 1 is waiting at the Receive node. Now, if the next message from the user is 'I need help with a laptop’ then- Scenario 1 - Checkbox is not enabled in Flow 2 and Flow 2 is in the same service as Flow 1.
The second message 'I need help with laptop' will trigger Flow 2 Start node and Flow 1 Receive node times out. - Scenario 2 - Checkbox is enabled in Flow 2 and Flow 2 is in the same service as Flow 1.
The second message 'I need help with a laptop' will resume only the Flow 1 Receive node.
- Scenario 1 - Checkbox is not enabled in Flow 2 and Flow 2 is in the same service as Flow 1.
- If Flow 1 and Flow 2 are in different services -
When there is an incoming message with the Help keyword, Flow 1 is triggered. We have a Receive node in Flow 1, Flow 1 is waiting at the Receive node. Now, if the next message from the user is 'I need help with a laptop’ then- Scenario 1 - Checkbox is not enabled in Flow 2 and Flow 2 (with keyword) is in a different service from Flow 1.
The second message 'I need help with laptop' will trigger the Flow 2 Start node and Flow 1 Receive node, and both get resumed. - Scenario 2 - Checkbox is enabled in Flow 2 and if Flow 2 is in a different service as Flow 1.
The second message 'I need help with a laptop' will resume only the Flow 1 Receive node.
- Scenario 1 - Checkbox is not enabled in Flow 2 and Flow 2 (with keyword) is in a different service from Flow 1.
Illustration
Let us look at an illustration to understand this clearly.
| Service 1 | Service 2 |
|---|---|
| Flow 1 - Start node configured with Help keyword followed by a Receive node with "*" as the keyword. | Flow 5 – Start node configured with "*" as the keyword followed by a Receive node with "*" as the keyword. You need to disable Flow 3 to enable this flow since Flow 5 is in a different service, you need to disable Flow 3. |
| Flow 2 - Start node configured with Help keyword followed by a Send SMS or any other node. | Flow 6 – Start node keyword configured with Balance keyword followed by a Receive node with "*" as keyword. |
| Flow 3 - Start node configured with "*" as the keyword followed by a Receive node with "*" as the keyword. | |
| Flow 4 - Start node configured with Loan keyword followed by a Receive node with "*" as keyword. |
The behavior of the flows is illustrated in the following table:
| Conditions (Trigger message and receive) | Checkbox status in different flows | Behavior |
|---|---|---|
| Message 1 – Help Message 2 - Loan | Enabled for Flow 1 Disabled for Flow 2 Enabled for Flow 3 Enabled for Flow 4 NA for Flow 5 Enabled/Disabled for Flow 6 | Message 1 triggers Flow 1 and Flow 2 Message 2 will be received by Flow 1 and Flow 2 receive node |
| Message 1 – Help Message 2 - Loan | Enabled for Flow 1 Disabled for Flow 2 Enabled for Flow 3 Disabled for Flow 4 NA for Flow 5 Enabled/Disabled for Flow 6 | Flow 1 and Flow 2 get triggered when Help is sent Message 2 triggers only Flow 4 and does not trigger Flow 3. |
| Message 1 – Total Message 2 - Loan | Enabled for Flow 1 Disabled for Flow 2 Disabled for Flow 3 Disabled for Flow 4 NA for Flow 5 Enabled/Disabled for Flow 6 | Message 1 triggers Flow 3 Message 2 triggers Flow 4 as the checkbox is disabled and will be received by Flow 3 Receive node |
| Message 1 – Total Message 2 - Loan | Enabled for Flow 1 Disabled for Flow 2 NA for Flow 3 Disabled for Flow 4 Enabled for Flow 5 Enabled/Disabled for Flow 6 | Message 1 triggers Flow 5 Message 2 triggers Flow 4 as the checkbox is disabled and will be received by Flow 5 Receive node |
| Message 1 – Total Message 2 - Balance | Enabled for Flow 1 Disabled for Flow 2 NA for Flow 3 Disabled for Flow 4 Enabled for Flow 5 Disabled for Flow 6 | Message 1 triggers Flow 5 Message 2 triggers Flow 6 as the checkbox is disabled and will be received by Flow 5 Receive node |
| Message 1 – Balance Message 2 - Loan | Enabled for Flow 1 Disabled for Flow 2 Disabled for Flow 3 Disabled for Flow 4 NA for Flow 5 Disabled for Flow 6 | Message 1 triggers Flow 6 Message 2 triggers Flow 3 and will be received by Flow 6 Receive node |

Flow Trigger Behaviour in Digital Channels
Note
This section is applicable to all the digital channels: WhatsApp, RCS, Messenger, Apple Messages for Business, Email, and Mobile and Web.
As an example WhatsApp is shown in the images.
Webex Connect allows you to trigger a flow on receiving an incoming message only if the configured conditions are met. Here is how you can use this feature:
Illustration
Let us look at an illustration to understand this clearly.
Scenario 1 - within Same Service
| Service 1 |
|---|
| Flow 1 - Start node event type (Postback for channel). Receive node waiting on ‘Incoming Message’ as event type. |
| Flow 2 - Start node event type (Incoming message for channel). Receive node waiting on ‘Incoming Message’ as event type. |
| Flow 3 - Start node event type (Inbound Webhook for channel). Receive node waiting on ‘Incoming Message’ as event type for channel. |
The behavior of the flows is illustrated in the following table:
