# Webhooks

Managing subscriptions from code, so your systems learn about a settlement as it happens. [Event Stream](/agents/event-stream.md) holds the event catalog and payload format.

***

## Subscribe

```
POST /v1/webhooks
```

### Body

```json
{
  "url": "https://yourapp.com/hooks/mansafi",
  "events": ["transfer.confirmed", "agent.transaction.pending_approval"]
}
```

### Response

```json
{
  "webhook_id": "wh_2c9f1a",
  "url": "https://yourapp.com/hooks/mansafi",
  "events": ["transfer.confirmed", "agent.transaction.pending_approval"],
  "secret": "whsec_xxxxxxxxxxxxxxxxxxxx",
  "created_at": "2026-07-02T09:00:00Z"
}
```

The `secret` appears once. It is what verifies the `X-MansaFi-Signature` header on deliveries.

***

## List

```
GET /v1/webhooks
```

***

## Remove

```
DELETE /v1/webhooks/{webhook_id}
```

Effective at once; nothing further is delivered to that subscription.

***

## Verifying a delivery

Deliveries carry `X-MansaFi-Signature`, an HMAC-SHA256 over the raw body keyed by your secret. Checking it takes a few lines:

```python
import hmac
import hashlib

def verify_signature(payload_bytes, signature_header, secret):
    expected = hmac.new(
        secret.encode(),
        payload_bytes,
        hashlib.sha256
    ).hexdigest()
    return hmac.compare_digest(expected, signature_header)
```

Anything failing that check should be dropped before it is processed.

***

## Replay

```
POST /v1/webhooks/{webhook_id}/replay/{event_id}
```

For when your endpoint was briefly down and you would rather pull one specific event back than wait out the retry schedule.

***

## Delivery history

```
GET /v1/webhooks/{webhook_id}/deliveries
```

Recent deliveries for a subscription with response codes and retry counts, so debugging starts from the full record rather than a guess.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.mansafi.xyz/api-reference/webhooks.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
