# Working in Meter Details
When you've created a Meter, you can open the Meter details page which is designed to help you perform common Meter management and operational tasks:
* [Reviewing Meter Details](/guides/usage-data-meters/working-in-meter-details#reviewing-meter-details)
* [Submitting and Checking Usage Data Measurements](/guides/usage-data-meters/working-in-meter-details#submitting-and-checking-usage-data-measurements)
* [Reviewing Meter Metadata](/guides/usage-data-meters/working-in-meter-details#reviewing-meter-metadata)
## Reviewing Meter Details
You can use the Meter details page to review and manage the Meter set up.
**To review Meter details:**
1. Select **Metering**. The **Meters** page opens and lists Meters by Product for **All products** together with any **Global** Meters.
2. If you want to review the details of a Product Meter, search or filter the page by **Product**.
3. Select the hotlink text of the Meter:
The **Meter details** page opens:
On this panel, you can:
* Read-off the Meter's **Name** and **Code**.
* Use the hotlink text to open directly the details of the **Product** the Meter belongs to. Note that if you've opened the details of a Global Meter, this will be shown under **Product**.
* Read-off the Meter's **ID** and **Copy** this to your clipboard.
* Check the audit data to see who **Created** and who **Last modified** the Meter.
* Review the **Data fields** that have been added to the Meter. These are listed as two types:
* **Measure data fields**.
* **Dimension data fields**.
* Review any **Derived fields** added to the Meter. Note that you can expand a **Derived field** to review it's calculation:
* If you intend to upload a a `CSV` formatted file for usage data measurements ingest for the Meter, use the **Download CSV template** button to obtain a file you can use for this purpose. See the [following section](/guides/usage-data-meters/working-in-meter-details#upload-csv) for further details.
## Submitting and Checking Usage Data Measurements
A **Submit measurements** panel is made available on **Meter details** pages. This facilitates the various ways you can submit usage data measurements into the m3ter platform for the specific Meter:
* [Ingest API](/guides/usage-data-meters/working-in-meter-details#ingest-api)
* [File Upload API](/guides/usage-data-meters/working-in-meter-details#file-upload-api)
* [Upload CSV](/guides/usage-data-meters/working-in-meter-details#upload-csv)
* [Submit usage data](/guides/usage-data-meters/working-in-meter-details#submit-usage-data)
* [Checking Usage Data Submissions](/guides/usage-data-meters/working-in-meter-details#checking-usage-data-submissions)
### Ingest API
The default selection under **Submit measurements** is **Ingest API**:
This option is designed to help you use the [Submit measurements](/api/measurements/submit-measurements) call for the m3ter Ingest API:
* The **Submission URL** is shown for the call with your Organization ID used, and you can **Copy** this to your clipboard.
* Five tabs are available for Meter-specific code samples to use for the call, and you can **Copy** the version you prefer to use:
* **JSON**
* **cURL**
* **JavaScript**
* **Python**
* **Java**
* If you are using this method to submit usage data measurements, please see [Getting Started with API Calls](/guides/billing-and-usage-data/submitting-usage-data/file-upload-service-api) for additional guidance.
### File Upload API
Under **Submit measurements**, select **File upload API**:
This option is designed to help you use the m3ter *File Upload Service API* to upload a usage data measurements data file to the platform:
* You can drag and drop a JSON file here containing an array of usage data measurements for ingest.
* Please review the [File Upload Service API topic](/guides/billing-and-usage-data/submitting-usage-data/file-upload-service-api) if you want to use this method.
### Upload CSV
Under **Submit measurements**, select **Upload CSV**:
This option is designed to help you use upload a `CSV` formatted file for Meter usage data measurements ingest:
* Please see the [File Uploads for Usage Data by Meter](/guides/billing-and-usage-data/submitting-usage-data/file-uploads-for-usage-data-by-meter) topic if you want to use this method
### Submit usage data
Under **Submit measurements**, select **Submit usage data**:
This option is designed to help you submit individual usage data measurements for the Meter and a selected **Account**, **Timestamp**, and optional **End Timestamp**:
* You can use a default **Simple** view and enter values for Meter Data fields or switch to an **Advanced** format and edit the JSON payload of usage measurements.
* Please review [Submitting Test Usage Data](/guides/billing-and-usage-data/submitting-usage-data/submitting-test-usage-data#submitting-test-usage-data) if you want to use this method.
### Checking Usage Data Submissions
If you scroll further down the **Meter details** page, you can use the **Activity** panel to check usage data measurement submissions made for the Meter:
* A *Recent measurements* list for the Meter for submissions made in the last hour and which were successfully ingested into the platform:
* Up to a maximum of the ten most recent submissions made in the last hour are listed.
* A *Measurement counts* chart showing a running count of submissions made for the Meter over the previous 24 hours:
* You can hover your cursor over the chart's hourly data points to read off actual measurement counts.
* Please see [Checking Usage Data Submissions](/guides/billing-and-usage-data/submitting-usage-data/submitting-test-usage-data#checking-test-usage-data-submissions) for more details.
## Reviewing Meter Metadata
On the metadata panel on **Meter details** pages under **Meter metadata** you can review:
**Custom fields**. Any Custom fields created for the Meter are listed, and you can **Copy** the *String* or *Number* value of a Custom Field to your clipboard:
* If the fields have been created only at Organizational-level, then these values will be shown:
* If the fields have also been created for an individual Meter, then the values configured for those created at Organizational-level are struck out indicating clearly that the individual Meter values will be used:
**External mappings**. Any External mappings set up for the Meter are listed:
* The **External system** and **External table** mapped to are shown - such as **NetSuite - Item** in the above example. The **External entity ID** mapped to is also shown.
* If a listed External mapping is linked to an Integration, under **Linked integration** a hotlink text will be shown which you can use to open the Integration.
* Under **Actions**, you can edit or delete the External mapping.
* If the Meter has multiple External mappings created for it, you can use *Search external mappings* to search by **External table** and **External entity ID** and filter the list.
* You can commence a workflow to **Create external mapping** for the Meter directly - see [Creating and Managing External Mappings for Accounts](/guides/end-customer-accounts/creating-and-managing-external-mappings-for-accounts) for an example.
**Integration runs**. If you've set up an integration that synchronizes the Meter with an external system, the date/time and status of the **Latest** integration run are shown. You can use a text hotlink to open details of this latest run or **View all runs**. See [Reviewing Integration Run Details](/guides/integrations/setting-up-integrations/reviewing-integration-run-details).
