# API tokens and webhooks

Administrators open **Workspace settings → Automation & API**. Full reference: [reach-book.com/developers](https://reach-book.com/developers), with Zapier and Make guides.

## API tokens

Click **Create token** and choose its abilities:

* Read prospects
* Create prospects
* Update prospect outcomes

Abilities can't be changed later. A token must expire within one year, is shown only once and starts with `rbk_`. It stops working if the person who created it loses admin access. The API allows 60 requests per minute.

## Webhooks

Click **Add webhook** and pick the events:

* Prospect created
* Prospect outcome updated
* Reply received
* Conversation assigned
* Opportunity updated
* Meeting booked
* Opportunity won

Rules for the receiving address:

* HTTPS on port 443, with no query string. Redirects aren't followed.
* Your service must answer with a 2xx status within 10 seconds.

Each request is signed with HMAC-SHA256 in the `Reachbook-Timestamp` and `Reachbook-Signature` headers, so you can check it came from Reach-book.com. Failed deliveries are retried after 1 minute, 5 minutes, 30 minutes and 2 hours (5 attempts in total). The **Activity** tab shows every delivery.
