Create (Webhooks)

URL:: https://<root>/services/<serviceName>.<serviceType>/webhooks/create
Methods:: POST
Required Capability:: Access allowed with either the "Geoprocessing" or "Feature layer" privileges
Version Introduced:: 11.1

Description

The create operation allows administrators to create a webhook for either an asynchronous geoprocessing service or a feature service. Once the webhook is invoked, it will deliver a payload to the configured payload URL.

For geoprocessing services, the webhook is triggered when the geoprocessing job is successfully completed, canceled, or fails to complete. For feature services, administrators can specify the event triggers for the webhook, which range from all possible feature service event triggers to being notified if a single event occurs, such as a feature being created.

To configure webhooks for a feature service, the feature service must include the editing capability and have change tracking enabled without sync. These properties can be modified using the Update Definition operation, which can be accessed in the ArcGIS REST Admin Services Directory by modifying the hosting or federated server's services directory URL as shown below, where <folder> and <serviceName> are changed to reflect the location of the feature service that will be updated:

https://machine.domain.com/webadaptor/rest/admin/services/<folder>/<serviceName>/FeatureServer/updateDefinition

To configure webhooks for non-hosted feature services, the data the service references from the enterprise geodatabase must be nonversioned and have archiving enabled. Starting at ArcGIS Enterprise 11.3, service webhooks support services with branch versioned data.

Webhook security

Starting at ArcGIS Enterprise 11.2, service webhooks use signature verification to ensure the integrity and security of webhook payloads sent from ArcGIS Enterprise to a webhook receiver. The input for the signatureKey parameter acts as a shared secret key between both ArcGIS Enterprise and the webhook receiver, which is known, and stored independently by, both ArcGIS Enterprise and the webhook receiver and used to determined if the payload is trusted. When a webhooks event is triggered, the secret key and the payload are hashed using a HMAC-SHA256 algorithm, creating the signature. The signature is then passed in the webhook request as the x-esriHook-Signature header value. When the webhook payload is delivered to the receiver, the receiver uses the secret key and payload to create a signature of its own using the same HMAC-SHA256 algorithm that ArcGIS Enterprise used. If the signature included in the request header matches the recalculated value created by the webhook receiver, the webhook payload can be trusted by the receiver. Otherwise, the receiver may choose to reject the incoming webhook payload.

Request parameters

Parameter Details

Parameter	Details
`name` (Required)	The webhook name. Example Example Use dark colors for code blocksCopy `1 name=Microsoft Flow`
`changeTypes` (Required for feature service webhooks)	Note This parameter is not applicable to geoprocessing service webhooks. Specifies the event triggers that will invoke the webhook. For more information about the supported event triggers listed below, see the Feature service event triggers section. The values for this parameter can be submitted as a string or as an array. Values: `*` \| `FeaturesCreated` \| `FeaturesUpdated` \| `FeaturesDeleted` \| `FeaturesEdited` \| `AttachmentsCreated` \| `AttachmentsUpdated` \| `AttachmentsDeleted` \| `LayerSchemaChanged` \| `LayerDefinitionChanged` \| `FeatureServiceDefinitionChanged` \| `FeaturesPosted` Example Use dark colors for code blocksCopy `1 2 3 4 5 //String example changeTypes=FeaturesDeleted, FeaturesEdited, FeaturesUpdated //Array example changeTypes=["FeaturesDeleted", "FeaturesEdited", "FeaturesUpdated"]`
`signatureKey` (Optional)	A user-defined alphanumerical string. Starting at ArcGIS Enterprise 11.2, the value provided for `signatureKey` is used by both ArcGIS Enterprise and the webhook receiver to ensure the authenticity of outgoing webhook requests. Example Use dark colors for code blocksCopy `1 signatureKey=123456789&ABCDE`
`hookUrl` (Required)	The payload URL where the payload will be delivered once the webhook is invoked. Example Use dark colors for code blocksCopy `1 hookUrl=https://app.logic.azure.com:443/workflows/...`
`contentType` (Optional)	Specifies the media type of the resource. The media type is a string sent with the file indicating the file's format. Values: `application/json` \| `application/x-www-form-urlencoded`
`payloadFormat` (Optional)	Specifies the response payload format. The default value is `json`. Values: `json` \| `pjson`
`active` (Optional)	Specifies whether callbacks will be enabled (`true`) or disabled (`false`) when a webhook is triggered. The default value is `true`. Values: `true` \| `false`
`scheduleInfo` (Optional for feature service webhooks)	Note This parameter is not applicable to geoprocessing service webhooks. The window for cataloging event triggers for a feature service. The modifiable values for this parameter are the `name` property, which allows you to provide a name of the schedule type, and the `interval` property, which sets the value for how frequently payloads will be delivered. For feature services that receive frequent updates, the schedule for its webhook can be modified to send more frequent payloads containing less information by reducing the `interval` value. For feature services that receive less frequent updates, the `interval` value can be raised to send less frequent webhooks that include more event information. The default, and minimum, value for the `interval` property is 20 seconds. Example Use dark colors for code blocksCopy `1 2 scheduleInfo={"name":"Every20Seconds","state":"enabled", "startAt":1670521784506,"recurrenceInfo":{"interval":20,"frequency":"second"}}`
`f`	The response format. The default format is `html`. Values: `html` \| `json` \| `pjson`
