With webhooks in Picqer, you can get push notifications when certain events happen in your Picqer account. With these webhooks, you do not need to poll the API anymore to see if a picklist is closed. You can just 'subscribe' to this event with our webhooks.
New to webhooks?
Receiving and processing webhooks is really simple. To give you a head start as a beginner, view our PHP example of a 4-line script that receives and processes a webhook.
We have a couple of events you can subscribe to. If you need an event we do not support yet, please let us know.
|orders.allocated||Triggered when an order is allocated|
|orders.closed||Triggered when you process an order|
|orders.status_changed||Triggered when the status of an order changes, e.g. from concept to processing or from completed to cancelled|
|orders.completed||Triggered when an order is completed, this is when all products are shipped to the customer|
|orders.notes.created||Triggered when a note is added to an order.|
|picklists.created||Triggered when a picklist is created|
|picklists.closed||Triggered when a picklist is closed|
|picklists.shipments.created||Triggered when a shipment is created on a picklist (can happen 0, 1 or multiple times per picklist)|
|picklists.snoozed||Triggered when a picklist is snoozed|
|picklists.unsnoozed||Triggered when a picklist is unsnoozed, either automatically or manually|
|products.changed||Triggered when a product is added or edited|
|products.free_stock_changed||Triggered when the free stock of a normal product is changed.|
|products.stock_changed||Triggered when the real stock of a normal product is changed. (Do not use this for tracking of free stock changes. Use free_stock_changed for that information.)|
|products.assembled_stock_changed||Triggered when the virtual stock of a virtual assembled product is changed.|
|purchase_orders.created||Triggered when a purchase order is created|
|purchase_orders.changed||Triggered when a purchase order is changed, like added or removed products|
|purchase_orders.purchased||Triggered when a purchase order is marked as purchased|
|purchase_orders.receipts.created||Triggered when a purchase order receipt is created|
|returns.created||Triggered when a return is created|
|returns.changed||Triggered when a return is edited, products or replacements are added|
|returns.status_changed||Triggered when the status of a return is changed, or when a comment/note is added|
|returns.products_received||Triggered when returned products for a return are received|
|movements.moved||Triggered when a movement is moved and the stock is changed|
When an event is triggered, you get a POST request on the given address. In the POST data we give information about the trigger and all data about the object involved. An example of the request we send you:
We expect you to give a 200 OK status code as a response. We ignore the content you send us. You have a maximum of 10 seconds to process the request, otherwise we also see it as a failure and we will retry.
Failures and retries
When we do not get a 200 OK status back from you, we consider the call as failed. We will retry to send the message 15 times in 24 hours. After 15 retries we delete the call from our queues.
Important: If a webhook fails too many times, we inactivate the hook. You can only reactivate the hook by registering a new one with the steps below. So make sure you handle possible errors on your side properly. Perhaps ignore a call and give a 200 state if you cannot process the request after multiple tries.
Registering your hooks
Adding and removing your subscriptions to these events, or 'hooks' as we call them, is only possible via the API. Below you find the documentation for managing your hooks.
For easier debugging, you can see details about recent deliveries for registered webhooks in your Picqer account. Go to Settings > Webhooks to see the webhooks. On the details page you see the recent deliveries Picqer made for this webhook.
|idhook||integer||generated||Unique Picqer reference|
|name||string||required||Your own reference for this hook|
|event||string||required||The event you want subscribe to|
|address||string||required||Your full endpoint for this hook, for example http://www.example.com/triggers/picqer-stock-change|
|secret||string||optional||If you provide a secret key with your webhook, we will use it to sign every request so you can check the sender, see "Validating webhooks"|

Deactivate a hook
To deactivate a hook you can use this delete call. This call will not actually delete the webhook, but it will deactivate the webhook. The webhook will be hidden from the API but can still be found in the Picqer web interface.
If you provide a secret while registering the webhook, we will sign deliveries of the webhook with a X-Picqer-Signature header.
The signature is created with an HMAC hash, using SHA256. We use the whole body of the request as the signed content.
For example, in PHP you can check the signature as follows:
$webhookPayloadRaw = file_get_contents('php://input'); $checkingSignature = base64_encode( hash_hmac('sha256', $webhookPayloadRaw, 'your-provided-secret', true) ); $isSignatureValid = hash_equals($checkingSignature, $_SERVER['HTTP_X_PICQER_SIGNATURE']);
