Step-by-Step Guide to Using External API in SendWo FlowBuilder

Follow the simple steps given below to build your own dynamic WhatsApp bot in SendWo.

Step 1: Create a Bot Flow with a Trigger Word

1. Log in to your SendWo Dashboard.
2. Navigate to Bot Reply and click to Create button.
3. Enter a flow name, for example: HTTP API Test Flow.
4. Assign a trigger keyword, such as httptest.

Step 2: Add an HTTP API Call Element

1. Inside your flow, drag the HTTP API element and connect it to the trigger node.
2. Choose your pre-configured GET request (for example: Product List API).
3. This will fetch your API endpoint and retrieve JSON data — such as product names, IDs, prices, and links.
   

Step 3: Add an Interactive Element

1. Next, drag an Interactive Message element into the flow.
2. Enter your prompt message, for example:
   
   • Text: Here’s our latest product list!
   • Button Label: Choose One...
     
3. Connect this to your previous API call step.

This step helps the bot introduces the list dynamically and let the user to pick from available options.
