When you integrate your 3rd-party external systems with the m3ter platform, entities and fields in external systems are mapped to m3ter entities and fields. External Mappings are created and act as mapping reference lookups for which entities and fields have been mapped across two or more systems. You can review these mapping references on the External Mappings page under Integrations where they are listed. When you are working to set up your Integrations and want to test or troubleshoot your implementation before going live, you might need to create External Mappings manually and, at a later date, edit or delete them. You can also create bulk mappings for specific mapping types. If you want to create multiple separate integrations for an external system, you can create external mappings for each separate integration, and these external mappings are then linked to the specific integration they were created for. This topic explains how to create and manage the External Mapping needed for the integrations with external systems you’ve set up for your Organization:Documentation Index

Creating Single External Mappings
From the External mappings page, you can create a single mapping of a specific mapping type. To create a single External Mapping:- Select Integrations:

- Select External mappings:

- Select the external system you want to view the external mappings for:

- The external systems available for creating external mappings for their integrations with m3ter are shown across the top of the page.
- If you want to view external mappings for another system, select it’s icon. The icon will be highlighted as the selected system.
-
For each external mapping, you can read off:
- Entity type. The m3ter entity the mapping is for.
- External table. The external table in the external system for the entity that is mapped to.
- Linked integration. If you’ve created the mapping as a linked external mapping, which means it can only be used for a specific integration for the external system, then the name of the specific integration is shown and you can select the hotlink text to open the integration’s details page directly. See Creating Linked External Mappings below for more details.
- m3ter ID. The id of the m3ter entity the mapping is for.
- External entity ID. The id of the external system entity that is mapped to.
- Select Create external mapping. To create a mapping, you must complete a two-stage workflow and the Create page opens ready for you to complete Stage 1.
- Enter External mapping settings:
- Use the Entity type drop-down to select the m3ter entity type you want to use to create the mapping type.
- Use the External system drop-down to select the 3rd-party system referenced.
- Use the External table drop-down to select the table in the selected 3rd-party system that you want to use for the mapping type:

- In this example, we’ve chosen to create an Account <> Contact mapping for m3ter <> Xero.
- When you’ve completed the mapping type set up, select Next. The page adjusts to allow you to complete Stage 2.
- The Entity type, External System, and External table you configured for Stage 1 are shown.
- Linked integration. Note that because you started the create external mapping workflow from the general External mappings page, this mapping will not be linked to a specific integration for the external system.
- On External mappings details:
- Use the m3ter entity drop-down to enter the specific m3ter entity of the type you’ve selected in Stage 1 - in this example a m3ter Account - you want to create the mapping for.
- In the External entity ID field, enter the ID of the external system entity you want to map to.

- Select Create external mapping. The Create page closes and the new external mapping is shown on the External mappings page for the external system:

- Note that if you select the hotlink text for the m3ter ID, this will open the Details page for the m3ter entity - in this example the Clean Graph Customer 1 Account - where the new external mapping will be listed under Account metadata. You can start a Create external mapping workflow for the Account from there - see Creating and Managing External Mappings for Accounts for more details:

Creating Bulk External Mappings
From the External mappings page, you can create mappings in bulk for a specific mapping type for an external system: To create External mappings in bulk:- Select Integrations:

- Select External mappings:

- Select the three-dot menu button at top-right of the page and then select Create in bulk:

- Enter External mapping settings:
- Use the Entity type drop-down to select the m3ter entity type you want to use to create the mapping type.
- The External system drop-down field will be preselected for the external system - in this example Chargebee.
- Use the External table drop-down to select the table in the selected 3rd-party system that you want to use for the mapping type:

- In this example, we’ve chosen to create Account <> Subscription mappings in bulk for m3ter <> Chargebee.
- When you’ve completed the mapping type set up, select Next. The page adjusts to allow you to complete Stage 2:
- The Entity type, External system, and External table you configured for Stage 1 are shown.
- Linked integration. Note that because you started the create bulk external mapping workflow from the general mappings page, none of the mappings will not be linked to a specific integration for the external system
- On the External mappings panel, select Add. The page adjusts to add a row for the first mapping:
- Use the m3ter entity drop-down to select the specific entity in your Organization you want to create the mapping for.
- In the External entity ID field, enter the id of the external system entity you want to map to.
- Select Add again and repeat up to a maximum of 20 mappings of the selected type:

- In this example, we’ve added four mappings of the selected Account <> Subscription mapping type for m3ter <> Chargebee.
- Select Create external mappings. You are returned to the External mappings page for the external system where the bulk mappings of the selected type are now listed:

Viewing and Managing External Mappings
From the External mappings page you can view and manage the external mappings created for your integrations with external systems and edit or delete them: To view and manage External Mappings:- Select Integrations. The Integrations page opens.
- In the sidebar, select External mappings.

- Select the external system you want to view and manage the external mappings for:

- If you want to edit a mapping, select Edit:

- On the Edit page, make your changes and select Update external mapping.
- If you want to delete a single mapping, select Delete:

- If you want to delete multiple mappings, check those you want to delete and click Delete selected:

Creating Linked External Mappings
If you intend to set up multiple integrations in m3ter with an external system, it’s a good idea to create separate external mappings for use with each separate integration. You can do this by creating linked external mappings from the details page of each of the integrations you’ve set up for an external system. For example, you might have your Xero system set up for two invoicing locations for your end-customers - UK and Europe. To serve this kind of use case:- You can set Xero Integration 1 for Bills outbound to your Xero UK invoicing instance and then create any required external mappings for the integration as linked to Xero Integration 1.
- You can set Xero Integration 2 for Bills outbound to your Xero Europe invoicing instance and then create any required external mappings for the integration as linked to Xero Integration 2.
- Select Integrations:

- Select the external system you want to create a linked external mappings for:

- On the Configurations panel, select the name hotlink text of the integration you want to create a linked external mapping for:

- Scroll down the page and on the Linked external mappings panel select Create external mapping:

- Enter External mapping settings:
- Use the Entity type drop-down to select the m3ter entity type you want to use to create the mapping type.
- The External system drop-down is preselected for the external system.
- Use the External table drop-down to select the table in the external system that you want to use for the mapping type:

- When you’ve completed the mapping type set up, select Next. The page adjusts to allow you to complete Stage 2:
- The Entity type, External System, and External table you configured for Stage 1 are shown.
- Linked integration. Note that because you started the create external mapping workflow from the Integration details page, this mapping will be linked to the specific integration for the external system and cannot be used for any other integration you’ve set up with that external system.
- On External mappings details:
- Use the m3ter entity drop-down to enter the specific m3ter entity of the type you’ve selected in Stage 1 - in this example the m3ter Account - you want to create the mapping for.
- In the External entity ID field, enter the ID of the 3rd-party system entity you want to map to.

- Select Create External mapping. The Create page closes and the new external mapping is shown on the Linked external mappings panel for the integration:
