Integrations & API
Connect WhatsApp to the tools you already run on
Trigger messages from store orders and payments, notify your team in Slack, and use a documented REST API and signed webhooks to integrate anything else.
What you get
Why teams choose integrations & api in LeadForGrow
Store and payment events
Order placed, paid, shipped or cancelled from Shopify and WooCommerce; payment captured or failed from Razorpay and Stripe.
Event → template
Map each event to an approved template with variables filled from the event, so customers get the right message automatically.
Slack notifications
Post new conversations, captured leads, failed messages, won deals and received payments to a channel.
REST API with keys
Send messages and templates, upsert contacts and track events with scoped, revocable API keys.
Signed outbound webhooks
Receive message, contact, campaign, deal and payment events at your URL, signed with HMAC-SHA256.
Verified, not trusted
Inbound provider events are verified with the provider's signature, and endpoints that keep failing are disabled automatically.

FAQ
Questions about integrations & api
Is there an API rate limit?
API keys are limited to a generous number of requests per minute. The limit is shown in Settings → Developer alongside the key.
How do I verify your webhooks?
Every delivery carries an X-LFG-Signature header — the HMAC-SHA256 of the raw body using your endpoint's secret. The docs include an example.
Can I connect Zapier, Make or n8n?
Yes. Use the generic webhook integration or the REST API from any automation platform that can make HTTP requests.
Where can I see the API reference?
In the documentation, which lists every public endpoint with example requests.
