HTTP POST SMS Campaign Builder

Use HTTP POST requests to trigger SMS campaigns from external systems — CRMs, marketing automation platforms, or custom applications. This enables automated campaign creation without manual JustCall dashboard interaction.

How It Works

1. An external system sends an HTTP POST request to a JustCall webhook endpoint.
2. The request includes recipient phone numbers, message content, and sending number.
3. JustCall creates and sends the campaign automatically.

Setup

1. Go to SMS/MMS → Bulk SMS → Integrations or API.
2. Find the HTTP POST Campaign section.
3. Copy the webhook URL and authentication token.
4. Configure your external system to send POST requests with the required payload:

{
  "phone_numbers": ["+15551234567", "+15559876543"],
  "message": "Your message here. Hi {{name}}!",
  "from_number": "+15550001111",
  "campaign_name": "March Promotion"
}

5. Test with a small list before sending to your full contact base.

Use Cases

• CRM workflow triggers — send a campaign when contacts move to a specific pipeline stage.
• E-commerce events — trigger abandoned cart or order confirmation SMS from your platform.
• Marketing automation — connect Keap, ActiveCampaign, or other platforms that support HTTP POST actions.
