A webhook tells your system that something happened in Orgo the moment it happens. Orgo sends an HTTP POST with the full record to a URL you control, so a CRM, a data warehouse or an automation platform stays current without polling the API. Built for teams keeping another system in step with Orgo. Replaces scheduled exports and “sync every 15 minutes” scripts. Webhooks page listing subscriptions with their URL, subscribed events, status, success and failure counts, last trigger time and per-row test, logs, edit and delete actions

​
Where it lives

Settings → Developers → Webhooks Creating, editing and deleting a subscription requires ADMIN_TENANT. Testing a webhook and reading its delivery logs are available on the same page.

​
Creating a subscription

Create Webhook form with the Active switch, name, endpoint URL, description and the six event type groups
1

Name the webhook

A descriptive name: the receiving system, not the event.
2

Enter the endpoint URL

Must be https and must resolve to a public address. A URL that resolves to a private or loopback address is rejected when you save it, and again at delivery time.
3

Pick the event types

At least one. They are grouped by family (see below).
4

Save, then test

The play button on the list sends a synthetic webhook.test delivery to the URL so you can confirm your endpoint answers before real traffic arrives.

​
Events you can subscribe to

Eighteen events in total. Each delivery carries the full record as it stands at that moment, and update events also carry the fields that changed. Passwords, tokens and connected-account identifiers are stripped before sending. The exact payload envelope, headers and per-event schemas are in the Webhooks reference.

​
Settings reference

Secret, custom headers and metadata sit behind Advanced Options on the form.

​
Verifying the signature

Set a Webhook Secret and every delivery to that subscription carries a signature your endpoint can check, so you can prove the request came from Orgo and not from someone who found your URL. Use a long random string, at least 32 characters, and store it in your own configuration exactly as you typed it here. The header looks like this:
t is the moment Orgo signed the delivery, in Unix seconds, and repeats the value in X-Webhook-Timestamp. v1 is an HMAC-SHA256, hex encoded, over the string t, a full stop, and the request body exactly as it arrived:
1

Read the raw body before anything parses it

Sign the bytes you received. A body that has been decoded and re-encoded to JSON is a different string, and the signature will not match.
2

Split the header on the comma

Take the value after t= and the value after v1=. Reject the delivery if the header is missing and you expect one.
3

Recompute the HMAC

Concatenate t, . and the raw body, run HMAC-SHA256 over it with your secret as the key, and hex encode the result.
4

Compare in constant time

Use your language’s constant-time comparison (hash_equals, crypto.timingSafeEqual, hmac.compare_digest), not ==. Reject the delivery if it differs.
5

Reject deliveries that are too old

Compare t against your own clock and refuse anything outside a tolerance you choose, five minutes being the usual figure. Because t is inside the signed string, nobody can change it without breaking the signature, which is what makes a captured delivery unusable later.
Working receivers in Node and Python are in the Webhooks reference. Two things to know before you set a tolerance. Each retry is signed again at the moment it is sent, so a redelivery arrives with a fresh t and a different v1, and a short window does not cause retries to fail. And because the same delivery can therefore carry different signatures, deduplicate on the payload id or on X-Webhook-Delivery, never on the signature.
The signature format changed in August 2026. Until then the header carried a short non-cryptographic checksum, which could be reproduced by anyone who had seen one delivery. A receiver written against the old value must be updated to the recipe above; the old header is not sent alongside the new one. Deliveries keep arriving either way, so nothing stops working while you migrate, but a receiver still comparing the old value is authenticating nothing.

​
Delivery and retries

Deliveries are queued, not sent inside the request that caused them, so a slow endpoint never slows down the app.
  • A 2xx response marks the delivery successful.
  • Anything else, a timeout or a TLS error counts as a failure and is retried until Max Retries is reached.
  • Retries back off exponentially, starting around 20 seconds and capped at 10 minutes between attempts.
  • Every attempt is logged, including the ones that eventually succeed.
A subscription is never deactivated automatically after repeated failures. Watch the Success / Failed / Total counters on the list, or your own monitoring. Because retries exist, the same event can arrive more than once. Make your handler idempotent by keying on the delivery’s id.

​
Delivery logs

The list icon on each row opens the delivery log for that subscription. Webhook delivery log table showing status, event type, response code, response time, attempt number, delivery ID and timestamp for recent attempts Each row shows the status (success, failed, pending), the event type, the HTTP response code your endpoint returned, the response time, which attempt it was, the delivery ID and when it was sent. The page loads 50 attempts by default and can show more; the API caps a single request at 500. The delivery ID also travels with the request as X-Webhook-Delivery, so a line in your own logs can be matched to a row here.

​
Troubleshooting

The endpoint must use https, the hostname must resolve, and it must not point at a private or loopback address. A local tunnel with a public https hostname works; http://localhost does not.
Check the subscription is active, that it is subscribed to the event you expect, and run the test delivery. If the test succeeds but real events do not appear, the action you are testing may not be one of the eighteen events above.
The request never completed: DNS, TLS or a timeout. Raise Timeout (seconds) if your handler does slow work, or better, acknowledge with 200 first and process afterwards.
Expected. Retries and at-least-once delivery mean duplicates happen. Deduplicate on the payload id.
Three usual causes, in order. Your framework parsed the body before you signed it, so you are hashing re-serialised JSON instead of the bytes that arrived. You hashed the body alone instead of <t>.<body>. Or the secret in your configuration is not character for character the one saved on the subscription, which you can settle by saving a new secret in both places at once.If you are checking a receiver written before August 2026, it is comparing the old checksum format and will never match the new header.
Poll the relevant endpoint on a schedule, or build the flow in n8n. The event list is fixed.
