Webhook tools and triggers for WhatsApp

Let your AI agent call your own endpoints for real answers — order status, booking slots, account balance — and let your systems start WhatsApp conversations by calling Repli.

Why teams choose Repli

What you get

Webhook tool builder

Describe an endpoint, its parameters and when to use it; the agent calls it during the chat and answers with the response.

Grounded AI replies

The agent uses your data for the answer instead of guessing, and says so when it cannot find a record.

Inbound triggers

Your systems can call Repli to start a conversation on an event you control.

Controlled access

Tools are scoped to your workspace and their calls are recorded for review.

Use cases

Order status

Answer “where is my order” from your own database.

Bookings

Check availability and confirm a slot in chat.

Account queries

Look up a balance, plan or ticket after verifying the customer.

Frequently asked questions

What is a webhook tool?

A described endpoint the AI agent may call mid-conversation, with the inputs it must gather first, so the reply uses live data from your system.

Do I need to write code?

You need an endpoint that returns the data. Configuring the tool inside Repli is a form, not code.

Can my system start a chat?

Yes, through an inbound webhook trigger, subject to WhatsApp’s template and messaging-window rules.

What if the endpoint fails?

The failure is logged and the agent responds without inventing an answer; the chat can be handed to a person.

Is this the official API?

Yes, messaging runs on the WhatsApp Cloud API.

Can a human take over?

Yes. Any conversation can be taken over in the shared inbox and the AI stops replying on that thread.
