Status: New | Priority: High, I’m very impatient | Created: 2025-11-12

Hello,
I’ve activated both the “change” and “cancel” triggers in my SimplyBook account, and configured my callback URL to receive updates.

However, the system never sends any POST requests to my endpoint when a booking is modified or canceled. I’ve confirmed:

The callback URL is publicly accessible (tested via curl / ngrok).

My endpoint works fine when tested manually.

I receive no webhook calls from SimplyBook.

Could you please verify if the callback triggers are working properly for my account or if there’s an internal issue?

Company : institutalgovita

Thank you!

Hi, please use any public available webhook test service to see the data we send. There is no problem with webhooks, we have many clients who are using it.

just used three public webhooks
https://hkdk.events/

https://webhook-test.com/

I canceled reservations, edit some and nothing being triggered for the bookings created through the api
but for the bookings created through the simplybook dashboard the callback actually worked

why ???

used this service just to check Webhook.site - Test, transform and automate Web requests and emails - you can see a request there for my test booking with mike@simplybook.me (webhook url is https://webhook.site/5ede06f6-c2f9-4188-9217-18e2c998b884 - now set in your settings)

yes, I’m receiving the create / edit / cancel request but only for the bookings created through the simplybook dashboard
for the bookings created through the API I don’t receive any response

as you can see, I created this booking through the API just now

Hi, you have price for the service.
Please pass
{
handle_invoice: true
}
to the $additional parameter.
Then after you confirm payment you will receive webhook.

email: clientDetails.email,
phone: clientDetails.phone,

SO when i remove accept payment plugin, it works
but i need to enable i could display prices, i found in accept payment plugin this option
“For those who don’t process online payments and only want to display prices, it may be helpful to skip this step.
Skip the payment confirmation step:”
when enabled now the callback don’t trigger

what workaround could i do ?
