Applies to: Dynamics 365 Organization 9.0+ with Field Service Solution 8.8.x version or Universal Resource Scheduling 3.8.x version
In this blog post lets talk about how to call the msdyn_SearchResourceAvailability API to return available resources.
At a high level, you pass the details of a single requirement (not a requirement group) to the API and retrieve a list of available resources and timeslots.
This is helpful for self-scheduling scenarios where a resource may want to query his or her availability, or for portal scheduling scenarios where a customer may want to view availability of desired resources from a web site or app.
To use this API, quick glance input and output parameter below and understand details below.
Input
- ResourceSpecification
- Preferred Resources
Output
- Time Slots.
- Time Slot Resource Characteristics
- Time Slot Availability Intervals
Input
| The version number of the API. See Version section more details |
|
The requirement to get availability for.
See Requirement section for more details.
|
| Settings for the request. See Settings section for more details. |
| Resource specification for the request |
Version
The version number identifies the version of the API that should be invoked. The version number is a semantic version number of the format major.minor.patch. The request does not have to contain the complete version number. See below table.
| Version number specified in request |
|
Invokes the highest minor and patch version available for the specified major version.
If we had versions 1.0.0, 1.0.1, 1.1.0, 1.1.1, 1.1.2, 2.0.0 2.1.0 and 2.1.1, the invoked version in the first example would be 1.1.2, because it is the highest version number available under major version 1. In the second example, the invoked version would be 2.1.1.
|
|
Invokes the highest patch version available for the specified major and minor version.
Using the same available versions as above, the invoked API version in the first example would be 1.0.1, because it is the highest available version number with the major/minor version 1.0. In the second example, it would be 2.0.0.
|
| Major.Minor.Patch version |
| Invokes the exact version number as specified. |
As of this writing, the highest and only version number available for this API is 1.0.0.
If no matching implementation for a version number specified in the request is available, the API will return an error.
Requirement
The requirement specifies the resource requirement to retrieve resource availability information for. This is expected to be a msdyn_resourcerequirement type entity.
This would typically be a requirement that is stored in the database, but it does not have to be. You can specify the details of the requirement in the entity without having a database record id. The intent is to call the API either using an existing requirement or construct one on the fly with the necessary constraints.
The entity should contain all the specifics that are relevant for your scenario. Below are some of the important attributes to populate.
| The remaining duration in minutes |
| The total duration in minutes |
Settings
Beyond the solution version and requirement details, you can pass along Settings for more filtered results such as retrieving available resources within a specific distance radius.
Settings are specified as attributes in an entity bag. The type of does not matter, you can specify any entity logical name.

|
| Specifies if the real time location of resources should be used when computing potential time slots. |
| Specifies the maximum travel radius for a resource to qualify for the requirement. See Travel Radius section for more details. |
| Specifies the sort order for the result. See Sort Order section for more details. |
|
MaxNumberOfResources
ToEvaluate
|
| Defines a limit on the number of resources that are considered for the request. |
| Resource Availability Retrieval Limit from schedulable entity definition |
Travel Radius
The maximum travel distance can be defined in an Entity. The type of entity does not matter, you can specify any entity logical name.
| The distance unit. See msdyn_distanceunit option set for possible values. |
Sort Order
The sort order can be specified using an entity collection. Each entity in the collection will represent one sort criteria. The type of entity does not matter, you can specify any entity logical name.
| The sort direction (0 for ascending, 1 for descending). |
ResourceSpecification
Resource specifications are defined as attributes in an entity bag. The type of entity does not matter, you can specify any entity logical name.
| The preferred resources. See Preferred Resources section for more details. |
| The restricted resources. See Restricted Resources section for more details. |
| The Id for the Retrieve Resources query. |
| The default Retrieve Resource Query Id. |
| The resource currently booked on the requirement |
Resource Types
Resource types can be specified using an entity collection. Each entity in the collection will represent one bookable resource type. The type of entity does not matter, you can specify any entity logical name.
| The option set value that represents |
Preferred Resources
Preferred resources can be specified using an entity collection of bookable resource entities. Each entity in the collection will represent one preferred resource.
| The bookable resource Id of the preferred resource. See the resourcetype attribute on the BookableResource entity for possible values. |
Restricted Resources
Restricted resources can be specified using an entity collection of bookable resource entities. Each entity in the collection will represent one restricted resource.
| The bookable resource Id of the restricted resource. |
Constraints
Additional constraints can be specified through attributes in this entity. The type of entity does not matter, you can specify any entity logical name.
Please review the Retrieve Resources Query on the schedule board settings to identify which constraints might apply. By default, it includes the following
| A collection of characteristic Ids that a qualified resource must have. |
| A collection of role Ids that a qualified resource must have. |
| A collection of territory Ids. A qualified resource must be assigned to one of the territories. |
| In combination with the Territories constraint, specifies that a qualified must be assigned to one of the territories or no territory at all. |
| A collection of organizational unit Ids. A qualified resource must be a member of one of the specified organizational units. |
| A collection of team Ids. A qualified resource must belong to one of the teams (implies that the resource type is a system user). |
| A of collection of business unit Ids. A qualified resource must belong to one of the business units (Implies that the resource is a system user). |
In each of the above constraints (with exception of the Boolean UnspecifiedTerritories attribute), the assigned value must be an EntityCollection where each entity in the collection defines one Id.
Use the logical name of the entity that the constraint refers to and the primary key name as attribute name.
For example, when defining a constraint on organizational units, the entity collection should be a collection of entities with the logical name msdyn_organizationalunit. Each entity in the collection should have an attribute with name msdyn_organizationalunitid. The value of that attribute should be a Guid that identifies the record.
