We’ve added a new way to control when people can book time with you in Scheduler: Specific Time Availability.
Nylas Scheduler lets your users set recurring open hours and block certain dates. Now, with Specific Time Availability, you can add one-time availability windows that take priority over your regular schedule and disappear automatically once they expire.
Specific Time Availability is designed to support a variety of scheduling needs, such as:
This flexibility helps your users accommodate special events, seasonal schedules, or last-minute availability changes without impacting your regular calendar settings.
With Scheduler Components v2.1.0, you can access Specific Time Availability in two places:
In the ‘Participants’ section of the Scheduler Editor, you can set the Specific time availability for a participant by adding one or more date and time ranges.
Adding these dates in the UI will work in conjunction with setting that participant’s Availability or open hours, but Specific time availability takes precedence.
You can either POST or PUT Specific date availability when creating or updating a Configuration. The specific_time_availability
object has three parts to it:
Here’s a sample request for updating an existing user’s configuration:
Update user’s configuration
curl --request PUT \
--url "https://api.us.nylas.com/v3/grants/<NYLAS_GRANT_ID>/scheduling/configurations/<SCHEDULER_CONFIGURATION_ID>" \
--header 'Accept: application/json, application/gzip' \
--header 'Authorization: Bearer <NYLAS_API_KEY>' \
--header 'Content-Type: application/json' \
