Webhooks
Receive signed HTTP notifications when your posts are published, scheduled, or fail
https://post.adaptlypost.com/post/api/v1/webhooksRegister a webhook endpoint. Every webhook receives all post events, signed with its secret.
Body parameters
| Parameter | Type | Description |
|---|---|---|
urlREQUIRED | string | Publicly reachable http(s) endpoint that will receive event deliveries. Private hosts are rejected. Max 10 webhooks per workspace. |
Events
Every registered webhook receives all of the following events. The event name is sent in the payload and in the x-adaptly-event header, so you can filter on your side.
| Event | Description |
|---|---|
post.published | All platforms of the post published successfully |
post.partially_failed | Some platforms published, others failed |
post.failed | Publishing failed on all platforms |
post.scheduled | A post was scheduled for a future date |
Verifying signatures
Every delivery is signed with your webhook secret (whsec_...). Compute an HMAC-SHA256 over "{timestamp}.{rawBody}" and compare it to the x-adaptly-signature header before trusting the payload.
The secret is shown only once
The signing secret (whsec_...) is returned only in the response to the create request — never in list, get, or update responses. Store it securely. If you lose it, delete the webhook and create a new one.const crypto = require('crypto');
const expected =
'sha256=' +
crypto
.createHmac('sha256', webhookSecret)
.update(`${req.headers['x-adaptly-timestamp']}.${rawBody}`)
.digest('hex');
const isValid = expected === req.headers['x-adaptly-signature'];Delivery and retries
Your endpoint must respond with a 2xx status within 10 seconds. Failed deliveries are retried up to 5 times with exponential backoff. Deliveries can arrive more than once — make your handler idempotent.
Auto-disable
After 20 consecutive failed deliveries the webhook is automatically disabled. Re-enable it via PATCH { "active": true } or from the dashboard.Managing webhooks
Webhooks are managed with the following endpoints, using the same API key authentication:
GET /api/v1/webhooks # list registered webhooks
GET /api/v1/webhooks/:id # get one webhook
PATCH /api/v1/webhooks/:id # update url or active
DELETE /api/v1/webhooks/:id # delete a webhook
POST /api/v1/webhooks/:id/test # send a signed webhook.test eventYou can also manage webhooks visually from the dashboard, in the API Tokens page.
OpenAPI specification
A machine-readable OpenAPI 3.0 spec of the entire REST API — including webhooks and the event payload schema — is publicly available. Import it into Make, n8n, or any OpenAPI-compatible tool to scaffold an integration.
