#### I am receiving numerous emails regarding authorization problems. How to fix it? <a href="#i-am-receiving-numerous-emails-regarding-authorization-problems.-how-to-fix-it" id="i-am-receiving-numerous-emails-regarding-authorization-problems.-how-to-fix-it"></a>

Meta often invalidates tokens for various reasons, such as traveling, incorrect login attempts, or the addition of new security mechanisms. To prevent any loss of data, we recommend adding a [backup token](https://docs.edgetag.io/channels/meta/configuration#backup-access-token) while setting up EdgeTag. This will bridge the time you need to re-authenticate the Meta channel in our app.

#### How do I confirm that Meta Channel is setup properly on EdgeTag?

There are few things you need to make sure the Meta Channel is setup correctly -

* Verify the events are firing using the validation steps - [refer the documentation](https://docs.edgetag.io/implementation/validation)
* Go to app.edgetag.io and visit the respective site and check events going to Meta on real-time logger. The real time logger is present on EdgeTag Dashboard.
* Verify events in Meta event manager dashboard

#### I am receiving numerous emails regarding authorization problems. How to fix it?

Facebook often invalidates tokens for various reasons, such as traveling, incorrect login attempts, or the addition of new security mechanisms. To prevent any loss of data, we recommend adding a [backup token](/channels/meta/configuration.md#backup-access-token). This will bridge the time you need to re-authenticate the Meta channel in our app.

#### I setup purchase\_NC and purchase\_RC but I don't see these events flowing into Meta.

* You must have a CRM connected to Edgetag. This CRM could be Shopify CRM, WooCommerce CRM, Salesforce CRM or BigCommerce CRM. Refer here for [CRM connections](https://docs.edgetag.io/crm-connections/shopify)
* The plugin for NC/RC should be added in the plugins section.
* For Meta, the NC/RC and FC events are automatically sent to the Pixel. For other Channels , kindly add the channel selection for any other channel in the plugin.&#x20;

#### Can I get first click attribution events sent to Meta?

Yes, you can send first click events to Meta. You will need to add the NC/RC plugin for it on your app/dashboard and enable First Click attribution checkbox on it

#### What access level do I need in Meta Business Manager to setup Meta Channel on EdgeTag?

You need to have full access to Meta Events manager to create new pixel as well as access to the main pixel for other validation and verifications.&#x20;

#### Should I setup Meta Channel on EdgeTag with my Main Pixel from day 1?

We do not recommend that and instead set up EdgeTag with a test pixel initially and until we do not move to the main pixel, we do not recommend running any campaigns on the test pixel.&#x20;

Follow these steps as the recommended best practice : \
\- Run both your existing main pixel and EdgeTag test pixel simultaneously\
\- Compare performance metrics between both setups over 7 days\
Performance Review & Migration After the 7-day testing period:\
Review performance data from both pixels\
\- Compare key metrics like event accuracy, conversion tracking, and data quality\
\- Once EdgeTag test pixel demonstrates better performance, migrate EdgeTag to your    main pixel

#### Do you recommend turning on browser pixel for Meta?

For the B pixel, we would want you to go with only server side implementation so that we have better data to compare. As browser implementation can be blocked by ad blocker or any other reason, which may effect during the validation stages.\
For the Main pixel, we'd recommend to turn on browser pixel so that deduplication can happen.

#### What is de-duplication in Meta?

Deduplication in Meta events (using both Pixel and Conversions API) prevents double-counting, ensuring accurate attribution, budget efficiency, and better campaign optimization by filtering duplicate server/browser signals using a unique Event ID

#### What Meta Channel related Analytics can I see in EdgeTag platform?

On the EdgeTag Dashboard, under the analytics tab you can see the performanced visually charted. You can filter with Facebook in channels section and see the total number of events, the time window can be edited for a 90 Day to an hourly view.\
You can enable real-time logger to see events going to Meta in real-time as well, present again on the Analytics dashboard.&#x20;
