Well this is weird. Did some more testing and i found that if I removed the / in front of the endpoint and the REST API started working again.
Eg. /info/ to info/

Yes i am in the Asia-Pacific region. From my logs it happened when the outage started.

Hi Simpro Tech Support,

Receiving an invalid route error on endpoint:
?.simprosuite.com/api/v1.0/info/

Note this is also the same for the other endpoints.
Works yesterday and the day before that but not today.

Thanks,

Godfrey.

Hi SimproAPITeam,

I removed the "Includes" parameter and this returns a successful response.

Hello Simpro Support, I use this endpoint to retrieve timesheets: /api/v1.0/companies/{companyID}/employees/{employeeID}/timesheets/ And use this query parameters: StartDate=2025-11-21 EndDate=2025-11-22 Includes=Job,Activity It used to send the correct results for the dates but now is returns this ...

Hi Support Team,

For "/api/v1.0/companies/{companyID}/sites/{siteID}/attachments/files/{ID}":
How would this API list the files in order of date created? In other words, show the latest file first.

Thanks,
Godfrey

Hi SimproAPITeam,

I did some testing and found that the response being returned from the URL is not the correct encoding.
The encoding of the message being returned was still in gzip format and not deflated.
Which then explains why Simpro is reporting a 406 not acceptable error.

Hi,

The header has not changed and there are no restrictions on the type of format accepted as far as i can tell.

Could the webhooks be blocked by the server? If so, what is the IP or URL so it can be whitelisted?

Thanks,
Godfrey.

Hi,

Here is the error message on Simpro showing the 406 response code: Thanks,

Hi,

How do i fix a 406 problem?
I have created several webhook events to a callback url.
And the response code is 406. It started on 13/1/2025. It worked fine before.
Do you know where I should start to figure out how to resolve this 406 problem?

Thanks,
Godfrey.
