Kapso API

Kapso Platform API

When to use

Use this skill for Platform API operations: creating customers, generating setup links, provisioning phone numbers, or detecting WhatsApp connections.

Setup

Base host: https://api.kapso.ai (scripts append /platform/v1)

Auth header:

X-API-Key: <api_key>

How to

Onboard a customer

1. Create customer: POST /customers
2. Generate setup link: POST /customers/:id/setup_links
3. Customer completes embedded signup
4. Use phone_number_id to send messages

Detect connection

Option A: Project webhook whatsapp.phone_number.created

Option B: Success redirect URL query params

Use both for best UX and backend reliability.

Provision phone numbers

When creating a setup link, set:

{
  "setup_link": {
    "provision_phone_number": true,
    "phone_number_country_isos": ["US"]
  }
}

Notes

• Platform API base: /platform/v1
