Build your SaaS on official WhatsApp Cloud API
WAstarter is a standalone Cloud API platform — the same job as a developer WhatsApp API. API keys, numbers, send and receive, inbox, templates, and webhooks. No Go High Level and no DML CRM required.
Official Cloud API. Use it on its own.
Embedded Signup — not a QR on someone’s phone. Multi-tenant keys and numbers. The same Cloud API stack can also run under DML CRM or the official GHL plugin if you want those later. You do not have to.
Official Meta Cloud API
Uses Meta’s official WhatsApp Cloud API. Customer-owned numbers, templates, and delivery on Meta’s pipe.
Embedded Signup
Connect a WhatsApp Business Account through Meta’s official Embedded Signup flow. Not a QR session.
Multi-tenant keys and numbers
Issue API keys and attach numbers per workspace. Built for SaaS and agency builders who need more than one tenant.
Send, receive, inbox
Send and receive on the Cloud API, and work the thread in an inbox. Live replies sit in Meta’s 24-hour customer-care window.
Templates
Message templates for outbound outside the care window. Meta bills those conversations separately from your WAstarter plan.
Webhooks
Inbound messages and delivery statuses come back on webhooks so your SaaS can react without polling a phone.
From Embedded Signup to your product
Embedded Signup
Connect the WhatsApp Business Account with Meta’s official flow. No QR code on a personal phone.

Send, inbox, webhooks
Send and receive through the API, work conversations in the inbox, and hook events into your own product.

Same standalone Cloud API job. Optional GHL or DML on the side.
Kapso is WhatsApp for developers: official WhatsApp API, send, webhooks, customer-owned numbers, and AI workflows. WAstarter does that standalone job too. Free, $25, and $299 line up closely. We do not claim a price win. Kapso is strong if you want their CLI, MCP, sandbox, Flows, and customer connection links. WAstarter is the Cloud API you can run alone — and you can also plug into the official GHL plugin (WAsndr) or DML CRM if you want that stack. You do not need either to use WAstarter.

Use WAstarter alone, or also plug into GHL or DML CRM
Pick one path. You do not need both. You do not need either. WAstarter is a full Cloud API platform by itself.
WAstarter only
API keys, numbers, send and receive, inbox, templates, webhooks. No GHL. No DML CRM. Built by Jorge / Double My Leads.
Open WAstarterOfficial GHL plugin (WAsndr)
WAsndr is WhatsApp for Go High Level — the QR / session path for GHL agencies. Plug in if you already run GHL. Not a requirement to use WAstarter.
See WAsndrDML CRM
Double My Leads’s own CRM and inbox. Use it if you want that workspace. The DML 7-day trial is that product, not a WAstarter trial.
