Due to the critical and confidential nature of the data being exchanged, all clients must adhere to the stated rules for implementing a webhook to eliminate potential risks.
Webhook Requirements
Your webhook should meet the following minimum performance requirements
- Must be an HTTPS endpoint
- Respond to all webhook events with a
200OK - Respond to all webhook events in
5seconds or less
Security Requirements
The HTTP request will contain an X-Hub-Signature header which contains the SHA1 signature of the request payload computed using the HMAC algorithm and the secret_key shared in advance, and prefixed with sha1=.
Your callback endpoint should verify this signature to validate the integrity and origin of the payload.
Error Handling and Recovering
If any of the below 3 conditions are observed by Haptik Systems when:
- We cannot connect to your webhook
- Your webhook takes more than '5' seconds to return the response
- Your webhook returns non 2xx status code
then
- We will retry the request 6 times over the course of
60 minutes(Retry intervals: 5 seconds, 25 seconds, 125 seconds, 625 seconds, 1410 seconds, 1410 seconds). - If the repeated webhook call are unsuccessful even after the last attempt we will automatically disable the webhook.
- Once the webhook is disabled, then new requests will be queued for a max duration of
60 minutes. Once the webhook is enabled by you, then we will attempt to deliver the requests. - You can visit the Haptik Dashboard or use the REST API to activate the webhook if it is disabled.
Note
There can be multiple delivery requests within a short time span and it is the client's responsibility to maintain ordering and QoS in case of failure to accept messages.
