- URL: https://[root]/services/[ServiceName].[ServiceType]/webhooks/[webhookID]/edit(POST only)
- Required Capability:Default administrator role | Feature layer | Geoprocessing
Nota:
Users assigned the Geoprocessing privilege will also require the Publish server-based layers privilege to be added to their custom role.
- Version Introduced:11.1
Description
The edit operation allows administrators to update a previously configured geoprocessing or feature service webhook. Once updated, the changes will be applied immediately. If the payload URL for a webhook has changed or if the event trigger for a feature service webhook has been updated, the new trigger or payload URL will be used when the webhook is next invoked.
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 |
|---|---|
| name (Required) | The webhook name. Example |
| changeTypes (Required for feature service webhooks) | Nota: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 Example |
| 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 |
| hookUrl (Required) | The payload URL where the payload will be delivered once the webhook is invoked. Example |
| 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) | Nota: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, formatted for readability |
| f | The response format. The default format is html. Values: html | json | pjson |
Feature service event triggers
The table below lists the supported event triggers for feature services:
| Event | Details |
|---|---|
| * | Any event is triggered. |
| FeaturesCreated | A feature is created. |
| FeaturesUpdated | A feature is updated. |
| FeaturesDeleted | A feature is deleted. |
| FeaturesEdited | A feature is edited (e.g., insert, update, or delete). |
| AttachmentsCreated | A new attachment is added to a feature. |
| AttachmentsUpdated | A feature attachment is updated. |
| AttachmentsDeleted | A feature attachment is deleted. |
| LayerSchemaChanged | A feature layer's schema is changed. |
| LayerDefinitionChanged | A feature layer's definition is changed. |
| FeatureServiceDefinitionChanged | A feature service's definition is changed. |
Example usage
The following is a sample POST request for the edit operation, editing a geoprocessing service webhook to use a new payload URL:
POST /webadaptor/admin/services/myService.GPServer/webhooks/create HTTPS/1.1
Host: machine.domain.com
Content-type: application/x-www-form-urlencoded
Content-Length: []
name=Microsoft Flow&signatureKey=123456789ABCDE&hookUrl=https://app.logic.azure.com:443/workflows/80fd5c68fcd84b3491b25330680ef1&payloadFormat=pjson&active=true&f=pjsonThe following is a sample POST request for the edit operation, editing a feature service to subscribe to an additional event trigger (FeaturesUpdated) and use a new payload URL:
POST /webadaptor/admin/services/myService.FeatureServer/webhooks/create HTTPS/1.1
Host: machine.domain.com
Content-type: application/x-www-form-urlencoded
Content-Length: []
