For each message sent from the Kommo interface to the chat channel, a webhook is dispatched to a specified address. Upon receiving a webhook, it’s crucial to process it and send a message to the messenger.

📘
Each webhook is sent only once; if the integration fails to process or receive it, it will not be retried.

Response time for the webhook is limited, so it’s recommended to check the request signature immediately upon receipt and handle business logic in the background. For example, you can queue a task for processing and promptly respond to the webhook.

If a message cannot be accepted by the integrated messenger, you should update its status to Error. Then, in an asynchronous mode, you can process the message, execute your business logic, and send the message as needed.

📘
Currently, the response window for the webhook is a maximum of 5 seconds. To consider the webhook successfully sent, your integration must respond with a 200 HTTP code.

The Chat API employs prioritization mechanisms; if the integration takes too long to respond or fails to respond, it may be moved to a slower stream, resulting in delayed webhook delivery. This priority is calculated dynamically based on various factors, allowing the integration to switch between faster and slower queues as necessary.

Additionally, “typing” events from the manager require separate webhook subscriptions for each channel, which can be arranged through Tech Support.

Webhook v2

Kommo sends you webhooks if a message was sent. To get them, you need to specify a webhook URL in "webhook_url" field when registering a channel.

Each webhook contains an X-Signature header, which is generated from the request body using the HMAC-SHA1 method. The channel secret serves as the secret key, allowing you to verify the authenticity of incoming webhooks.

To do this, calculate the hash from the body of the incoming request and compare it with the value in the X-Signature header.
