Potential recently introduced bug on Create Webhook call? (POST /webhooks)
Our Smartsheet integration has occasional need to create a webhook before it knows the ultimate URL for the callback. For several years, we have done this by supplying a dummy URL to the CreateWebhook (POST /webhooks) API and then before we verify that webhook, we update the URL with the POST /webhooks API and set it to…
How can I pull reports data from Resource Management connect to Power BI?
I'm not a developer and my knowledge of APIs are limited. I'm working on getting data from the resource management tool to power bi. I was able to pull all data, except for reports.

Test bed for new deprecations?
Hello, with the substantial API deprecations that were announced last week, will there be a test-bed on which we can test our proposed changes to ensure we have caught all possible deprecated access attempts before the main production service URL enacts the deprecation? If so, when (ish) and how might we access the test…

(exact same behaviour for querying folders…

Does a view-only user need a license to use the API?
Hello everyone, I will need to use Smartsheet API to ingest data from Smartsheet to an object storage. To do that, my client will create a view only account for me.
