Also known as “ER2ER”, "DAS2DAS", or “EarthRanger to EarthRanger”, event sharing allows you to share events and subjects between two EarthRanger sites.

Event Sharing

I. Audience

• EarthRanger Support Team.
• Deployment Partners.

II. Prerequisites

Source Site

• Permissions. Create a user with permissions to read the event categories that will be shared with the destination.
• Authentication Token. Create a session token for this user. 
   

Destination Site

• Permissions. Create an EarthRanger user (e.g., “er2er_event_sharing”) with the “Gundi Service Account” permission set to allow the integration to create the necessary event categories and event types.
• Authentication Token. Create a session token for this user (e.g., “er2er_event_sharing”).
• Event Categories and Event Types. Although you can let the integration create the necessary event categories and event types, you may also choose to create them manually. 
  If you choose to create these manually, please read the section “Destination Event Schema” within the “Additional Technical Documentation” section in this article, and configure update_schema to false in Gundi.

IV. Configuring Gundi v1

Go to Gundi v1.

Go to the Inbound Integrations and select Add Integration.

Follow the steps below to configure the integration:

Follow these steps to complete the form:

Name: Provide an appropriate name for this connection (e.g., ER Site 1 to ER Site 2)

Organization: Select the relevant organization.

Type: Choose “ER2ER”.

Endpoint: API endpoint of the source ER system.

Token:  Token for the user session token on the source ER system.

State:  

{
   "days_to_sync":{{number}},
   "delete_unmatched_events":{{boolean}},
   "dest_endpoint":"{{site url}}/api/v1.0",
   "dest_token":"{{string}}",
   "prepend_system_to_categories":{{boolean}},
   "prepend_system_to_event_types":{{boolean}},
   "prepend_system_to_event_titles":{{boolean}},
   "source_system_name":"{{string}}",
   "source_system_value":"{{string}}",
   "update_schema":{{boolean}},
   "within_featuregroups":[
      "{{string}}"
   ]
}

{
   "days_to_sync":10,
   "delete_unmatched_events":false,
   "dest_endpoint":"https://sandbox.pamdas.org/api/v1.0",
   "dest_token":"0Kfl3LOh0bIgKwcYVoGVWknLMxjh6h",
   "prepend_system_to_categories":true,
   "prepend_system_to_event_types":true,
   "prepend_system_to_event_titles":true,
   "source_system_name":"VCC",
   "source_system_value":"vcc",
   "update_schema":true,
   "within_featuregroups":[
      "2b2b7728-c215-434c-bf01-a9796d5e9a7b"
   ]
}

Click Save.

V. Configurations in the Destination site

a. Manual Event Schema Updates

Important:

When update_schema is set to False, the following fields need to be added manually to each event type schema. These properties need to be added to the Properties section, but not to the Definition section. 

   "er2er_src_id":{
      "type":"string",
      "title":"Event Type Serial Number from Source ER System"
   },
   "er2er_src_system":{
      "type":"string",
      "title":"Name of Source ER System"
   },
   "er2er_src_serial_number":{
      "type":"string",
      "title":"Serial Number of Source Event"
   },
   "er2er_src_service_root":{
      "type":"string",
      "title":"Service Root of Source Event"
   }

b. Adjusting Permissions (Required Step)

Important:

• After the initial successful run of the integration, the destination site will contain a copy of the event categories and types from the source site. However, the integration does not automatically grant the necessary permission sets to the EarthRanger user (e.g., “er2er_event_sharing”) on the destination site. You must manually assign the permission set(s) named after the event categories created by ER2ER during that first run.
• While you may remove the “Gundi Service Account” permission set from the user after the initial integration, ensure the user retains permissions to read, add, update, and delete event types, especially if update_schema is set to True in Gundi.

Troubleshooting 

In Gundi (v1), the Inbound Configuration is constantly updated with two dates that are helpful for troubleshooting:

last_run indicates the last time the integration ran, whether successfully or not. 

last_successful_run indicates the last time the integration ran without errors. This date is also used to specify the time window for pulling events from the source site. If this date is not present, the integration will set the start date based on the number days_to_sync.

In case of errors, the Inbound Configuration “State” will include the errors that blocked the integration from running successfully, and the Inbound Configuration will be flagged with an “Error" label, allowing users to find it when searching for inbound configurations with errors.
